I am yet to be an i30 owner...

The CRDi is ruled out due to no particular filter [I consider it a 'dirty' vehicle] so we are considering a 2.0 petrol automatic wagon instead

We have based our ownership cost figures over 10 years and also based on urban/city cycle of 10.3L/100 as I feel that better respresents our suburbian driving. At 10.3 I don't consider the i30 economical especially compared to say a VW Golf TDI that does 5.7 ! [but costs $10K more]

1. What have peoples experience being with 2.0 auto economy in suburban driving conditions with no climate control/AC ?

2. Did economy improve with 98 E10 ?

1. What have peoples experience being with 2.0 auto economy in suburban driving conditions with no climate control/AC ?

2. Did economy improve with 98 E10 ?

i have a petrol auto hatch. i am mainly highway driving with semi town and have done one lot of city driving in it so far. i'm averaging 8.5 currently on the highway and when i travelled down the city i peaked at 10.9 i think from memory. actually it may have even hit 11 briefly but then came back down again pretty quickly. with town driving i may push up to say 8.8 and a few days of highway can drop down to as low as 8.2. i can get it into the 7's if i constantly drive around 90 k's or so with no stopping/starting/revving but this is hard on both the highway and in town traffic

i have never used standard unleaded in the car just either premium 95 or premium 98. to be honest i have found little difference between these two and a woolworths/caltex 95 can give me an average of 8.6 while the more expensive shell 98 can give me a 8.2. but somehow the shell 98 just 'feels' better.

i always use the air con, to be honest i'm not sure you save much by not using it, especially if you climate control it. i do live in hot hot queensland though so need it in summer.

and i wouldn't use E10 if you paid me

Snowcherry thank you for the reply

Our driving pattern would be described as follows: 5 days of 2 short surburban return trips and 2 weekend days of 2 medium return trips into the city and 2 short suburban trips. I have this feeling [hoping] I would get somewhere between city economy of 10.3 and combined 7.7 therefore 9L/100 ?

How come you won't use E10 ?

[Surferdude]

I'm getting 7.6 to 8.2 per tank in my 2.0 litre manual.
Aircon is always on and as I'm an old rally driver I drive reasonably hard.
Most tankfulls are around town (Sunshine Coast) with occasional trips to Brisbane mixed in.
Got 8,000 klm up now and there has been a gradual improvement.
I have to say, it's better than I hoped for.

Thank you too for the reply.

A manual does slightly better economy [0.3-0.5/L100] than the auto but your figures are very good especially if you have A/C on all the time

I wonder what type of driving is needed to average 10.3, mind you all our short trips involving going up hills and I noticed hills send the economy right up

I bought the manual for two reasons. Firstly for driving pleasure and secondly for economy.
Also have roof racks (cross bars) so they would have a slightly detrimental effect.
BTW. Hills send the economy "down". But fuel consumption "up".
Sorry. Get anal sometimes.
Also, was the VW you quoted above the diesel? Can't imagine that good a consumption figure from a petrol engine.

[Duckman]

Surferdude, methinks it is the diesel, quoted as Golf TDI.

Anywho, I average about 7,2l/100km, although I do mainly freeway driving. As with surferdude's comments, I average the same when I drive local areas.

Basic efficient driving will get you the posted average readings by Hyundai (actually, add a litre or two considering they drive like nannas!). The highest recorded reading for my 2.0l petrol was 10l/100km, although, after 50,000km, I can't seem to push it much above what my average is now at 7.2l. Amazing little engine we have here!

[snowcherry]

How come you won't use E10 ?

it's all personal choice, my father swears by using E10 in his 6 cylinder Ford Ute and says it does better economy than using premium 98. but from what i've read into it premium 98 is a cleaner fuel over the very long term and is kinder to your engine [no personal experience in the matter though]. as i have no idea whether i'll keep my SR short term or maybe 10 years i'd rather be as good to it as i can be.

my driving also i may add does include some hills. i think if it was all flat around here my economy would improve. i also do overtaking and driving at 100 or so definantly pushes the economy up vs sitting at a granny'ish pace of 80-90. if you have a lot stop/start driving and hills then yeah you might be in the 10's but if not you may even see your car go lower than that.

2. Did economy improve with 98 E10 ?

Economy will drop with E10 because energy per unit volume is lower than petrol.

It does however promote a higher octane rating which, if useable, is an advantage but it generally ends up being cost neutral compared to normal petrol. Essentially: cheaper to buy but doesn't go as far. It also has negatives for "normal" engines and is the reason it is limited to 10% mix. Not sure I'd want run it in my engine long term, particularly as any advantages are debatable.

I assume your interest in using it is because it is presumed to be environmentally better: 1) Being produced from renewable crops and 2) less polluting.

The renewable crop thing worries me. Even if it is made from the waste from edible crop production, for instance cane sugar, I'm not convinced that it might not also be made from purpose grown crops which I think would be better used to grow crops that feed us instead. It's the same problem as using plant derived oil in diesels.

The pollutants from burning it in cars may or not be better. Here's just one simple to understand site offering more information.

Me, I'll stick to drinking my ethanol.

i did not mention it earlier but another reason i don't 'personally' use E10 are some concerns about this supposed "green" factor. there is a lot of negative press about how it takes as much , if not more, fossil fuel to make E10 than to just use the fossil fuel directly in the first place, meanwhile using extra crops and water on top - presuming not using waste materials only. so until i guess i see some concrete evidence that there are no negatives in the process as far as the environment goes i'd just rather steer clear of it.
but maybe i'm just falling for the doomsday hype

 the use of ethanol based petrol in our cars WILL void our warranties.

Obviously I haven't got this concern with my i30  but I doubt E10 would void your warranty...

I haven't studied the manual that closely but I would have thought the i30 Petrol would have been engineered to cope with that level of ethanol (unlike some older cars...)

[2i30s]

in our oz owners manuals it states not to use ethanol based petrol and bio diesel.!

[agentr31]

hyundai state, and i quote "do not use ethanol containing more than 10% ethanol, and do not use petrol or ethanol containing any methanol" (section 1, page 3)

im assuming they mean pertol containing more than 10% ethanol... its a bit unclear there

i hate ethanol blend fuels... ive never used them they are just bad news... alcohol is bad for rubbers and plastics and thats what your fuel system is made from, plus ehtanol has a higher oxygen content, thus making your o2 sensor think there is less fuel being injected and it "richens" the mixture up to compensate, creating the "more fuel used" problem with blend...

ethanol also absorbs moisture so your now adding an agent to the tank that will draw moisture into the fuel system... dont belive me get metho and add it to water, give it a stir and its mixed in...

it says we can use bio-diesel BUT in concentrations at less than 7% refer to section 1 page 5 of the owners manual.

bah just stick to standard fuel and you will be alright

In NZ Hyundai allow E10 under warrenty

The NZ Govt did a detailed study on the Sustainability of Brazilian Sugarcane Ethanol and this found that despite shipping and growing it was sustainable and better for the environment not to mention employing millions of farmers in Brazil. It does not use rainforest areas or compete for food. However there are some concerns about workers conditions. You can read it here http://www.eeca.govt.nz/sites/all/files/sustainability-brazilian-sugarcane-report-08.pdf just read the executive summary

ahh cheers for that - interesting read (well breeze through)
i didn't know about the brazilian industry and it certainly does look sustainable. i had a quick google as well and saw a few comments saying something like its the 'only true green' industry or similar.
kudos for NZ looking into that then.

[SergeyAU]

Still on my first tank of petrol from buying 2009 2L Auto... Got to say, its a different experience from my previous car (Ford Laser 2001).
Only 130km traveled - 1/4 tank gone! Don't really like the gauges  on i30. Arm on the gauge is fat - hard to tell where it is at... 10.5/100 so far - waiting for my obd2 to get more precise figures... Mainly suburban driving with little freeway

[Pranav]

Mini is a 2 Lt Auto Wagon. Done 3000 Km's

Am getting around 8.5 to 9 litre per 100 Km's

Driving has been a mix of 80 % Highway and 20 % City.

Am not too happy with the figures, hoping it improves as the engine gets roused with some more use.

[Ralph1]

We have a 2010 i30CW 2.0 auto with 9,000 ks, we are currently getting aroung 9.5 around town, we use E10 as I think they say not to use a mix of over 10%, E10 is 10%, but I may change to normal 95.

We used to have a 2004 Corolla 1.8 auto and got 7.8 ish around town.
 
cheers

[SandRsSR]

Our 2.0 Auto SR has been getting somewhere in the 8s arround town, maybe 9 at the worst. Our last trip to Dunsborough gave us 7.3 mostly highway driving. These figures are from the computer but any measurement I have done to calculate manually has backed up these figures in the past.

My opinion:

The Golf will be a nice vehicle but troublesome to maintain.

I get fantastic economy from my 2.0L petrol, I run it on 95.  I used to own a Ford Fiesta with the dual clutch auto, and Ford were always going on about how much more efficient this was than a regular torqu converter setup.  Truth is, I get better efficiency out of this than I did from the Fiesta, and the hyundai is a heavier car with a bigger engine, and the regular auto.

The diesels are really quite tough fantastic cars.  I couldn't afford one or I would have bought one, filter aside.  You could always look into an after market one.

All diesel hyundai i30s I've seen on the road don't spew out the black cloud a lot of volkswagen/audi/toyotas do though...  They don't sound like a tractor either.  Nice vehicles.

you should bear in mind you are driving a wagon which is a bit heavier than the hatch version.  I'd be happy with those figures although you are right, the engine might still have some loosening up to do.

My Fiesta got similar/worse figures and it was a tiny car with a 1.6 and an automated manual box.

Manufacturers get their fuel figures from dyno tests and the like, real world will always be very different.

It also depends on how you drive and how you treat your car.  Put the right fuel in it, avoid short trips, don't floor it when it's cold etc will all help.
