Hi Everyone
I've just used up the first tankful for my CRDi 1.6 i30. Mileage was at 598 miles when the DTE changed from "30" to "---" and I drove a further 13 miles before refilling (52.88l or 56 quids worth). Well chuffed! :D
I zeroed the "av mpg" after filling up and was amazed to see a peak of 79.6mpg while tootling through the 30mph zone for the first mile or so!!! Is this a record??? :eek:
-
... and was amazed to see a peak of 79.6mpg while tootling through the 30mph zone for the first mile or so!!! Is this a record??? :eek:
No :P
I once zeroed the mpg meter while on a run down the M6 on a downhill section. It read well over 120mpg after half a mile, but then again I wasn't using any accelerator :lol:
Anyway, stop cheatin
-
"...It read well over 120mpg..."
Well. There's a challenge if ever there was one. The gloves are off matey! :lol:
-
Got a "98.6" today. Getting closer!
Second tankful lasted 667miles (1073km) before "---" started. Car's a gud'n.

That's a Gr8 result for just your 2nd tank full :-)
-
Yes, that's what I thought.
Then again, I have been driving like an old biddy.
I'm becoming obsessed with driving economically, am I ill?
Shambles is "a doctor" perhaps he can help me!
-
iThurT.. In my opinion you need to do some spirited driving while running her in or she won't perform at her best...
It's not an illness (most of us on here do it from time to time) but don't forget to enjoy the torque occasionally :-)
-
I found that when I drove ultra-conservatively everywhere that the economy got worse. I also found that the other end of the spectrum, driving like I stole it, gave worse economy as well. I get the best economy when I mix it up with both spirited driving and sedate driving. This is years of empirical evidence speaking because I noticed the same with my previous car (V6 petrol).
-
on my third tank, sitting on 500 odd km and its probably still 2/3rds full still.
yaaaaaay! i love that its run in now and im getting the mileage out of it now!
-
Yes, a new engine should be given some work. Although I have been occasionally 'letting her rip', perhaps I should be doing it a bit more often.

As much as I think this sounds nuts, I actually agree with you.. Molly Coddling it does NOTHING.
-
More agreement here too.
I don't believe in "thrashing" engines, but they should perhaps be subjected to a little bit of "pressure," especially when running-in. It does them more good than harm I've found to have to work a bit rather than be molly-coddled(?)
I've just gently expanded the rev-range on my crdi since new, stretching its legs, never caning it, but not consistently driving for economy either and it is freeing up nicely and the economy is starting to improve too.
In my previous life, I've run-in numerous pursuit cars and the dealerships always said that the police cars that worked really hard from day one, were always less troublesome over their life and performed better than the average Joe Citizen's car, but then what it does to the longevity of the engine I'm not sure.
-

Like, every other gear maybe????
I just can't help it !
-
Fist off, are we all used to diesel's? or are you talking about petrol motors?
as the too are a lot different to run in.
diesels you put a load on them, get them to pull lower rev's in top gear, this pushes the rings out to wear a sealing.
diesels don't like high rev's.
i ran my motor in below 2,000, and was getting good economy from low k's.
a lot of people that have always had petrol cars and move to there first diesel rev the motor too hard all the time.
diesls won't last as long if you rev them hard all the time. but its good to give them the boot once a week or so just not give them a high rev, i think that variable vane primary stage in the turbo would need to move regularly to stop it carboning up.
mine seemed to perform better after 30,000k it is performing strongly now and still gets good economy, but i think it always got good economy as i never fill up till after i've traveled at least 1,000k that is unless i'm planing to do a realy long tip. i don't like stopping for fuel.
-
My fuel economy is almost 4 months the same. I reset it once in a while and it usually stops at 5,6-5,7 lit/100 km.
Hm..what do you guys understand as high rpm? Regarding the fact that 1.6 CRDIs unfortunately don't have 6th gear, you have to drive it at 3,000 rpm (at those rpms it goes 140kph) all the time.. I usually drive on highways (every day 80-100 km) and normal travel speed is as I mentioned around 140 kph. That means you have to drive it between 2,800-3,500 rpm in fifth.. The i30 is great, but it would be really perfect if it just had 6th gear - for longevity of the engine and fuel economy :rolleyes: But okay, it isn't that much of a problem.
-
what is the tacko red line on a crdi. :question:
-
what is the tacko red line on a crdi. :question:
5500RPM (I think - from memory)
accim .. few of us in Aus would spend much time driving our i30 at more than 120kph (most highway limits over here 100 or 110 Kph..) and lots of speed cameras...
If we drove at 140kph all the time we would want 6th gear even more...
-
3,000rpm is starting to get at the point you are reving a diesel too high, i know they feel ok, but they won't last as long. i try to keep mine below 2,500 if i'm on a trip, for short bursts it won't hurt, but over 3,500 is a waist as they don't seem to excellerate hard after about 3,500 as tq falls off. but everyone is free to do as they please :wink: cheers
-
Yeah I taught so. Well I try to drive around 130 kph (which is the speed limit on the highways) but it's much more "comfortable" (because you fit in) if you drive 140 kph. Even the cops find that speed normal, because the cameras are mostly set to "over 140 or 150 kph". Mostly every one drives with that speed and if you go slower they get frustrated very soon. Well some do drive also 160-200 all the time, but that's their problem. I also like to push it over 180 kph sometimes but really rarely, because I feel bad for the engine. Oh well enough about that..back to fuel economy.
I see quite some of you have managed to drive 1,000 kms+ with one tank.. I still haven't managed to do that, my record was 950 km I think. But considering the fact I drive with speeds around 140 a lot of time, that also sounds like a good accomplishment. Ole for the i30's CRDI :wink:
-

You are probably not taking an extra few minutes to squeeze in an extra 5 litres or more either .. (which I only do sometimes...)

Sometimes I used to squeeze in some extra 3-5 litres, but then I stopped doing that, because I heard some people had problems later with filters (they got "flooded" or something like that??) I remember one guy had that problem with Santa Fe. Still, I find approx 920-950 km a good result.
Interesting, I'm just watching this interview on the TV and it's about this guy from Slovenia, that went to Australia in 2002 and has been living there since.. Very interesting things I've heard :wink: One of the things he mentioned was also, how he admires that when the speed limit is 110, people really drive 110 kph (most of people), or some 120 kph and not like it's here, that people drive 160, 180.. hhh. Don't know exactly which part of Australia he said he was from, but I know he said something about the "golden beach" ? Ok, it's time to go to bed slowly and I keep posting offtopics..sorry :rolleyes:
-
Hi Accim, well that is partly true, mostly if you are around City's here there will be fixed speed camera's. state to state the laws change, but generally maxium speed nationaly is 110KPH but in Northern Territory they have a higher maxium speed, but they never used to have a speed limit out of the towns.
That guy would be in Queensland state on the Gold Coast, that's the southern part of Queensland queensland state is about 1,500k to 2,000k long and about 800k to 1,000k wide.
but if you are way out in middle of no where here you don't see anyone and you don't see many police so your on your own, problem is it's a long way between service stations where you buy fuel and if you drive really fast you could run out and depending were you are you might be on your own for days.
cheers

I have been looking everywhere for this information - what economy will I get at 130-140kms.
I am in Oz, but where I drive I see a cop maybe once a year at most and that is on the sealed roads, which is about half of what I drive on.
I have been looking for this info for ages and very happy I found this!
I also wish that they had a 6sp Manual as this would be perfect.
Interesting to read some comments from people about the diesel. I havent event got mine yet, but not pushing it too hard doesnt sound like much fun!
The Kia Rio I have at the moment is about 4yrs old and has done 115K. Never missed a beat and that has been hammerred from Day 1. Unfortunately the fuel economy at about 140 is around 9.5L/10KMS and if you push it hard it can be above 11L/100KMs. Be interesting to see how the new i30 goes, although I probably will be a little nicer and not do say, 5k RPM for 200km of backroads, when I am running late ;-)!
-
At that speed (130-140 Kph) Nat you should still not go over 6 LPH..(especially in flat old WA) It would be pointless to ever rev the diesel to 5000rpm. When in a hurry you will find changing at even 3500rpm will send you rocketing forward..
-
Interesting notes from the i30 owners manual -
No special break-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
• Do not race the engine.
• While driving, keep your engine speed (rpm, or revolutions per minute) between 2,000 rpm and 4,000 rpm.
• Do not maintain a single speed for long periods of time, either fast or slow. Varying engine speed is needed to properly break-in the engine.
• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.
• Don't let the engine idle longer than 3 minutes at one time.
• Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
Most interesting is its recommendation to keep RPM between 2 and 4k. This seems to be very different to what other here have been doing. They don't seem to recommend anything different for petrol or diesel engines.
-
Hi marvy and welcome to the club :wink:
Nice little reminder there.. thanks..
Us diesel owners tend to keep between 1500 and 2500 if trying for best economy but perhaps wouldn't have laboured the motor too close to the 1500rpm mark very often when the car was just new...
-
OK, seems like appropriate thread to post my "first tank" data:
Poured in 47ltr to the first click when trip computer was showing 50km to empty. Took the readings when there were ~30km to empty.
Results:
Distance traveled: 841km
Average consumption: 5.5ltr
Average speed: 40kph
Conditions: semi-urban, trips <30km, average temp most probably few degrees below 0C.
-
Last week we did the first longer trip with our i30CW.
280km to one direction. About half of it motorway (120km/h limit) and most of the rest 100km/h limited road. Drive through one town. Two persons and the luggage. Speed limits were followed with the normal +5 km/h police tolerance taken into account.
Average consumption on the whole 560km was 4.9 liters per 100km.
Not bad, since there is only 3500km on the meter and the car is still noticeably "stiff".
We btw. tested the accuracy of the speedo with both the GPS navi and some speed display boards on the way. Quite a surprise, as I have been accustome to the fact that speedos generally are always quite optimistic, showing around 5% too much.
Not so with i30, the speedo is accurate within it's physical readability between 50km/h and 120 km/h. That is police patrol car class accuracy!

That is interesting penak (several of us Aussies have done the same thing with Korean made cars...) and the concensus here is between 5 & 8% optomistic depending on who you ask...

Agreed. 5% at best. This is an odd observation when you consider we are talking about the same units (kmh). Maybe they fixed it!
-
Both my 09 and my current i30 show 2-3mph optimistic at a GPS measured 70mph (< 5%) and maintains a similar percentage above and below this speed. As accurate as anything I've ever seen and as good as you can reasonably expect. Then again, the GPS could be miles out! :-[

I did some experiments with speedo and my GPS, here are the results (km/h):
| Speedo | GPS |
| 40 | 36 |
| 50 | 47 |
| 60 | 57 |
| 70 | 68 |
| 80 | 78 |
| 90 | 88 |
| 100 | 98 |
| 110 | 108 |
| 120 | 118 |
At lower speeds the speedo seems to be less accurate, but at higher speeds accuracy is very good indeed.
-
Hi saunaman,
Again that is different to my findings over here .. from memory..
about 5kph overreads at 60kph (GPS says around 55kph) and by 120kph (GPS says something like 113kph)
Not that I find it a problem as i have a fairly large speed readout on my MIO GPS and use that on longer trips :cool:

We both have 6-speed Czech-made I30's. Are you using 195/65-15 too?
The speedo will get more optimistic with tire wear, but with ones used for only ~2000km (on the first 1500, the car was on studded M+S tires) it seems to be accurate.
-

I'm having the standard 195/65-15 set of Hankooks, driven about 3500 km with them. I'm noticing slight increase in noise from tires touching the road surface, thus idicating some sort of tire wear.
Generally, I am happy with speedo accuracy - it is the most accurate one I have ever had. My previous car (Mazda 6 -07) had 6 km/h lower actual speed at 100 km/h mark on the clock.
Still waiting for slightly better fuel consumption figures, currenty I'm doing about 5.3-5.7 l/100km figures at 65-70 km/h avgerage speeds. 70% of my driving is at speed limit ranges 80-120 km/h and 30% at ranges 40-70 km/h. My record figure was 5.1 l/100km with winter tires and lower winter speed limits.

I have just filled up my new UK (Czech made) CRDi Comfort automatic for 2nd time. Having driven it gently as it is so new - including a longish 180 mile run collecting the car - I have only got about 440 miles on the 1st tankful. I reckon that is about 40ish to the gallon. Thats not bad but it is a bit "son-in-law" (ie I had hoped for better!).
I know its a torque converter auto etc, but should I expect better? Do CRDi's improve with a few miles under their bonnets?
Anyway - its a very nice car, does its job well, is good to drive and quite agile.
-
Do CRDi's improve with a few miles under their bonnets?
My manual Crdi has stayed fairly consistent with her fuel useage but quite a few other CRDi owners on here report fairly significant improvements over time...
-
mines on its 3rd tank of fuel... first got around 900, 2nd got 970 (with a touch more to go) hopefully this one cracks 1000 then i will be truly stoked with this little car!

how many litres did those tanks use?
-
52L
-
the reason i say a touch more to go... the light hadnt come on yet and the gauge was still above empty by about a needle width if that makes sense to you

Because Tassie is so hilly and I just drive "normally" I usually only just crack the 1000 km mark if I fill her up close to "chockers" :wink:
On my recent trip I went Devonport to Hobart drove around all over the place in Hobart including 3 or four trips to Howden which is probably 25kms south of Hobart (where my Auntie lives) then came home via Launceston (did some tripping around there too). I then had a hurried :wink: trip via Frankford (nice winding backroad) and then still had enough to go to Burnie yesterday to do some relief work... still no light on :eek: (reckon I could have got to Burnie and back again today without running out but decided to get a refill in Devonport last night..
Did well over 900 with 2 adults and lots of luggage most of the time... It's worth looking at a map of Tassie to see where I went (it really hits home just how "convenient" these little CRDi's are :mrgreen:
-

Nice! That's about 5.3L/100km. I wish I could get to 1000km. My last tank was something like 880kms, my trip computer was flashing -- saying I had no km til empty but when I filled I only put in 48L. This tank is filled right up so I'm gonna try push it further even if it says --. Oh and the needle was below the empty line..
-
if, my fuel light is on for say 30k & i fill to the top, 57L is about it so you boys have 1,000k plus per tank don't be shy.
cheers
-
if i changed my driving style a bit it would probably also help...
meh im happy with what i does... its f#*&ing unbeliveable...
-
Yes i guess if you shift at below 2,500 to 3,000 it helps, but i drive mine how i want and i use the Torque & the boost for the thrust it gives, and i go over 1,000 per tank, unless i'm about to do a trip and have to fill up b4 leaving. they seem to feel even better 30,000k & up. but economy for me has always stayed the same it's more to do with how i drive. but still 1,000k per tank is easy. 1,400 takes more self control & needs to be in rural area, & on longer trip so motor is @ runing temps
-
Another pertinent question is which fuel do you both use? This is also an important factor. I have been using Shell diesel this whole time...
-
shell diesel...
-
i use Caltex vortex diesel, but have used BP, Shell & Mobil. i have never noticed a gain in economy useing Vortex, just motor feels more responcive.
-
The economy of the CRDi is impressive I agree. On my second tank at the moment and I am estimating I'll get just over 800km at 5.7l/100km. Considering I have been driving a Ford Territory with an average consumption of just over 13l/100km I'm feeling pretty happy with my snappy i30.... :D

I am currently looking at an upgrade to something bigger (after more than 2 years with my CRDi manual ...) and won't even consider anything that does worse than 8 LPH..makes the list fairly short...as I have already dropped a few for other reasons (too ugly, poor resale etc..)
-
hybrid camry??? you have to admit they do look pretty nice!!

Dazz what about a SV6 Comodore with the new motor? my brother in Law got one about 3 months ago and loves it say's gets good economy, i think they shut cylinders down if you drive slow or cruise or idle, he gets 8L/100k he say's. he got it to tow his boat but has not towed yet as too cold for the boat.
-
put that very same commo in heavy trafic in stop start conditions... i doubt it would get that sort of economy... i30 on the other hand...
-
hybrid camry??? you have to admit they do look pretty nice!!
I had a Hybrid Camry recently for a whole day did something like 130 kms and averaged under 7 but felt fairly unresponsive for 140kw and a little bit bland in the styling for me and over 40K on the road for the lesser model... (think I can do better for that money)
Hi John,
Would be surprised if the new SIDI commodore would average 8.0 or less feedback i've heard is closer to 9 average and more if you give them a bit of stick (I could be wrong) They are good value at the moment around 35K with 18" alloys and leather :eek:

well, with larger cars, and small motors you can't expect excitement. bro in law has driven everything, as he has a dealers & wholesalers licence but just about retired now, still he has good contacts and he is impressed with the way the commo performs and how good economy is. me i don't like the look of the rear . especialy the wing on the boot, they look square & fat from the rear. but there is not much choice. i drove my V8 ute 70 k across syd & back yesturday and trip computer showed 9.7 average per 100k, used the M7 motorway for part of the trip but was in traffic.
my Ute does not shut cylinders down, like the commo so when i idle i have 8 cylinders taking fuel & firing. the way the new V6 & V8 commo's work the 8 can be in 4 @ idle the 6 can be on 3 @ idle so in traffic idling they could surprise you. but for me you can't tell me your doing it to save money Dazz LOL.
go and buy an Audi.
cheers
-
Of over 25 cars I have had only one 6 Cyl and one very thirsty 2.4 Magna most of the rest have been very good on fuel....(I inherited tight genes)
I like the look of the new Commodore and Falcon for that matter and they are both good value but couldn't live with that fuel economy..
I like to keep my overheads down.. Getting quite self sufficient on our two acres (tank water and seweridge...nice veggie garden etc...)
If I keep my fuel economy low might be able to chuck my job all together... :mrgreen:
-
you could make your own fuel. :rolleyes: :lol:
-
thats great Dazz. good for you too, we have a vege patch & fruit tree's too. & large rain water tank .
will be good to see what way you go, with new car.
cheers
-
you could make your own fuel. :rolleyes: :lol:
Don't know about that, however...my Brother has just built a new house in Kingscliff (N.S.W.)and is generating more power than he can use :eek: Unfortunately in Tassie the rebates etc.. are far less attractive (or I would be doing that too...)
We ar going to put in a small orchard :D
Sorry for the off topic.. :-[

we went out in a mates VY last night... sitting at 100 for about 80km then 20km of city driving then the return trip... it got 8.2l/100km effing suprised the hell out of me

Gosh! Are you sure that you do not have punctured an extra hole in your tank..? Is that an actual fuel consumption figure or just a reading in the display?
I'm currently doing 5.0-5.5 l/100km average figures, calculated after each fill-up (have 8500+km on the clock).
In mid-july I am going to put my i30cw into a real test - heading to a holiday drive to Lapland and northern Norway. That'll make about 3000km in 6 days, longest single distance driven in a day will be 850 km from southern Finland to the arctic circle.
It will be interesting to see how the consumption figures develop during the trip. I believe that especially the driving in norwegian fjells and mountains will take the figures up, otherwise I do expect record-low numbers 5.0 or less.
-
LOL, its the dodgy trip computer... didnt thing about how cr@p they are at the time
-
I'm halfway through my first tankful and have clocked up 482kms - all city driving (inc a heavily congested freeway to/from work).

My first tankful came out at 49mpg with the computer reading 52.5mpg. Not brilliant so hoping for better as time goes on.
I was revving the engine higher than I would normally due to the bit in the manual stating to try and keep the revs between 2,000 and 4,000 for the first 600 miles. Now got 850 on the clock so will see what this tankful gives me.
-
... keep the revs between 2,000 and 4,000 for the first 600 miles...
I think your manual has the same misprint as mine (rev range quoted for petrol instead of diesel :eek:). You wouldn't want to rev a tight diesel engine that high so early in its life.
-
Well I just got 1076kms from 62L which equals 5.7L/100km. Computer said 5.4L/100km and 48km/hr average. Using Shell diesel.
I think if my average speed was higher I'd get more kms out of the tank.
-
Mine seems to be getting better with the 2nd tankful.....
-
I think if my average speed was higher I'd get more kms out of the tank.
Strange as it sounds that seems to be how it works .. my best economy seems to relate back to an average speed of 50 to 70 kph (which requires a good % of highway driving)

Yeah, you can obviously tell I sit in quite an amount of heavy traffic and the highway driving I do isn't enough to compensate.

Hi Mutley, i've never got 62L into my tank yet, most i've got was 57L. HOW Many K's did you go with fuel warning light on?
-

Hi Lakes,
The tank + piping all the way up to the top can fit 64L. After the light came on I think I went another 130kms. You can get 100km after the DTE goes to --- but no more. I go about 80km after this and because of this I was left with 2L in the car.
Also currently on this tank I have done 500kms and have 3/4 of a tank left. Computer says 5.1L/100km.
-
thats good to know, i get about 500k @ 3/4 and about 700k@ half
-
for my new i30cw auto 1.6L diesel, first tankful :
843km, 46.09 litres = 16.53km/l or 6.05 l/100km
This is for 98% driving on country roads, hopefully will get down to around 5.5 l/100km once it is well run in.
I don't know if the auto can manage 1000km to a tank, need to get down to 5 l/100km.
Have any auto diesel drivers achieved 1000km to a tank without seriously overfilling the tank?
At what point on the fuel gauge is the indicator pointing to when you run out of fuel?
-

2 needle widths past empty is when you have no more diesel left lol.

843 km on 46 litres is a great result at this early stage..
I can't remember an auto owner posting a 1000km result on here (although I guess it is technically possible)

Ummm.....it's one of those running jokes. Also if you click my original post it takes you to a whole thread about how you can add ...."that's what she said".....to most comments.
So in context to the joke, it wasn't aimed at the poster, but at the comment itself.

I'd like to revise this statement. 1.5 needle widths is empty hehe. I would say once you have a full needle thickness below empty you have about 50kms MAX to go so really I wouldn't go much further after you have a full needle thickness below empty.

I've heard that it's very bad to run a tank to empty (apparently more so for diesels than ULP)?
Any truth to this - or do we need Mythbusters?

I don't think petrol models are any concern. I've heard that it's possible to suck up water from the bottom of the tank but I can't see why that's any less likely with a full tank. The pickup is at the bottom anyway.
Diesel will require priming at the fuel filter but again I don't see that as a big deal and probably reduces the amount of cranking to get the fuel through, which is a good thing.
-

I certainly wouldn't try and do it ...but by my understanding the diesel has a very effective bosch filter (it should be as it retails for over A$100) so I think the risk of damaging the motor with contaminants is minimal..
Feedback on here is that if you completely run out it takes a bit of priming but no real drama..

That's right :wink: No drama at all...if you know what you need to do.
If you run out just put about 10L in, take the top fuel line off the fuel filter and prime it by pushing the big silver button up and down until fuel flows out. Connect the hose and away you go!

I have never really understood it. Given that you use a car regularly, there will come a time when you end up pushing it to the limit as far as driving with a near empty tank. At this point all the accumulated dregs at the bottom of your fuel tank will be sucked into the fuel line but hopefully filtered properly.
So is it so bad for the fuel filter to take a big hit of dregs every year or 2 or is it worse if it happens a few times a year?
-
well it depends LOL if the fuel filter is almost blocked it might block it up
i would be more worried about water in the system! water and engines dont mix... even more so for a diesel!
-
people always say there will be dirt in the tank, but they are just guessing, also most tanks take the fuel from the top not the bottom they use fuel pumps not gravity feed.
my nephew drove his new common rail turbo diesel over to show me a few years back. when he went to leave. it would not start was out of fuel. he had 24 hour nissan assistance. they told him the system self primes. was same as the i30 CRDi had the button on to of fuel filter. we went got 5Lt's of diesel put it in the tank. still would not start. phonned nissan they asked if it was parked on level ground. it was on a hill facing downward so we moved it to level ground and a few turns it firred up ran sweet. no problems kept it three years sold to his mate , just got a new diesel, he loves the diesels now like i do.

Lakes, please explain in more detail.
If the fuel is taken from the top of the tank, what happens when you use some. How can it pick up fule if there is air there.
I haven't pulled a tank apart for many years but it seems logical to me that the pick up will be at the lowest point of the tank, regardless of the age of the car.
-
obviously the pick up is at the bottom... about 1 cm from the bottom, its actually in a swirl pot... well sort of a swirl pot just 2 bits sitting up to help prevent fuel starvation durning cornering...
infact most petrols have an intank filter!!! usually its just really fine wire mesh or in my maxima's case a "sock" that fits over the intank fuel pump!
if we were guessing that fuel was contaminated/dirty then there would be no need for an inline fuel filter...
-
i just ment the fuel line comes from the top of the tank not the bottom. like agent said petrol have pump in the tank.
i have always filled my tanks to the top and run to the fuel light, unless i'm going on a long trip then i fill right up b4 i leave.

So you agree it doesn't matter how far down you run your tank.
My wife won't let hers get below a third before she fills up - learnt from her father. My argument is that fuel is cleaner these days and fuel filters more effective so it shouldn't be an issue.

I agree, especially with a new car. The only way filth would get into your tank is if you put it in there.

Well i have never had a problem yet and over 40 years & millions of K's travelled so i'm not about to change. i think its easier to find good fuel @ a good price in the city as higher turn over, so i like to be able to fill up in city drive out country & return on same tank. sometimes i do 1,200k b4 i get back to city.
the good thing about your wife keeping tank up is she won't run out of fuel, some people cut it too fine.

filth gets in your tank from every other tank the fuel had been in since it was refined!
it has a chance to collect dirt ect ect from the minute its made, the pipes it travles in, to the storage tanks its stored in, then the pipes its sent to load out in, then the truck that its loaded in, to the storage tanks at the service station, then in the bowser and finally your tank! dont forget all the tanks are probably mild steel that the fuel is stored in, then water gets in there, condenses at the top of the tank, causes rust that inturn falls into teh fuel so there is another contaminent...
just think if 1 grain of dirt got in for every 50L (say an average car fuel tank) and at every stage its handled then thats a lot of gunk over the course of the life of your car...
-
^^^
Thanks for that.
Good stuff from someone in the know. :cool:
-
well im not exactly in the know! just know a little!
-
Well yes. But I think where you work might give you an advantage.
:wink: :cool:

Tanks Ian.. very logical case you put there :mrgreen:
-
All ian said would be true, But in this day and age we have some very good filtration systems. i'm sure the big three would filtrate there fuel.
also for petrol, everytime fuel is pumped or poured it looses octain. the octain rating we see at the bowser in Australia is Refinery octaine Number not what the octain is at the pump. in the USA they get pump octain number so our 98 octain would be more like the american 93 octaine. i buy race fuel when i race at that has a motor octain number, the designations are RON,PON or MON.
the servo i get my Vortex has a large externat filter on the diesel bowser
-
almost lakes!! it doesnt quite loose octane because its poured or pumped!
Good quality gasoline should be stable almost indefinitely if stored properly. Such storage should be in an airtight container, to prevent oxidation or water vapors mixing, and at a stable cool temperature, to reduce the chance of the container leaking. When gasoline is not stored correctly and is left for a period of time, gums and varnishes may build up and precipitate in the gasoline, causing "stale fuel"
basically being exposed to the atmosphere for a long time will make your fuel stale! its the better parts of the fuel (benzine and tolulene) "evaproating" that ruin petrol
octane rating can be confusing, i cant explain it properly so... wikipedia will for me LOL
Research Octane Number (RON)
The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.
[edit] Motor Octane Number (MON)
There is another type of octane rating, called Motor Octane Number (MON), or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load as it is done at 900 rpm instead of the 600 rpm of the RON[2][3]. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally, fuel specifications require both a minimum RON and a minimum MON.[citation needed]
[edit] Anti-Knock Index (AKI)
In most countries, including all of those of Australia and Europe the "headline" octane rating shown on the pump is the RON, but in Canada, the United States and some other countries, like Brazil[4], the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI, and often written on pumps as (R+M)/2). It may also sometimes be called the Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2.
[edit] Difference between RON and AKI
Because of the 8 to 10 point difference noted above, the octane rating shown in the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel. See the table in the following section for a comparison
i really should ask my bosses if they can line up a tour of the refinery for me one day... im sure i could learn quite a bit from it
*agent puts on some nomex overalls in hope of this ever happening*

Almost Agent!! The word you were both looking for is: "lose".
:rolleyes:
-
i only learnt that from an industial chemist i raced with he used to mix his own fuel told me every time you pour or pump fuel it looses some octaine. specialised race fuel surplier told me the same.
but for the average motorist would not matter.
now tell me about Nitro BP dopn't make that
cheers

yer i guess lakes! because you are mixing air into it, and thats bad for fuel! (as we both know)
nitro!!! what do you race? im interested!!!!

In mid-july I am going to put my i30cw into a real test - heading to a holiday drive to Lapland and northern Norway. That'll make about 3000km in 6 days, longest single distance driven in a day will be 850 km from southern Finland to the arctic circle.
It will be interesting to see how the consumption figures develop during the trip. I believe that especially the driving in norwegian fjells and mountains will take the figures up, otherwise I do expect record-low numbers 5.0 or less.
It's been a while since my last visit to this forum, so I have a bit catching-up to do... But anyway, I did that trip I advertised above, somewhat 2900 kms alltogether.
The average diesel consumption figure for the whole trip was 4.8 l/100km, but for my surprise I got the lowest figures whilst driving in the northern side of arctic circle - stunning 3.8 l/100km. I would have expected that going hills up and down would have taken the figures up, but quite the opposite happened.
I was able to keep good average speed and stressless driving whilst up in the north. Coming down to south took the figures back up to my regular level, driving here is more "busy" and requires frequent slow-downs and accelerations...
At the moment I've got 15 500 km on the clock, the car works still like a charm.
-
Good average for that type of terrain saunaman .. I have traded mine on a larger car a Toyota Camry Hybrid and I use about 1 LPH more on average but it seems to be similar to the i30 CRDi as to what makes it go up and down (but sometimes no rhyme or reason..) :rolleyes:
-
Well for the first time my computer calculated correctly. It said 5.6L/100km and thats exactly what I got. Of course it took 14500kms to get there though!
Also found out in order to get 4.7L/100km or around that you need an average speed of above 70km/hr. About 68km/hr will get about 5L/100km.
Service on Monday 4th Oct......5months after picking it up :)

thats some deacent KM's you have done there broham!

indeed, will slow quite considerably start of november though....work from home...awww yeah :lol: :cool: :D
