Fuel economy of new 1.6 CRDi

THE i30 · **November 14, 2012, 05:15:10**

My new i30 has just clicked over 3000km and my last tank of fuel filled brim to brim with 45 litres of fuel returned 970km, that's 21.5 km per litre. That was around 30% around town and & 70% on the highway with cruise control set at 110km/hr and even towed a light trailer for 125km on the highway during the tank. I think that is awesome figures for a new diesel they tell me it will keep getting better until 10000km

So nice you got 6 speed manual.

Phil №❶ · **Reply #2: November 14, 2012, 05:26:42**

Well done

THE i30 · **Reply #3: November 14, 2012, 05:44:48**

Yeah it's the 6 speed manual, just love it the ratios are perfect for the torque range of the engine

Good economy that. So the 2012 i30 has a 45 litre tanks whilst previous models had the 54 litre tank? or is it just the diesel that has the smaller tank?

Phil №❶ · **Reply #5: November 14, 2012, 06:36:03**

I don't think the tank was near empty Lester. It just took 45 litres to brim it.

Doggie 1 · **Reply #6: November 14, 2012, 07:18:57**

It should be 53 litres but I usually put 58 litres in, sometimes 60 +.

i30sean · **Reply #7: November 14, 2012, 18:30:05**

Thats 602mls in UK figures I regulary fill up on 525-550mls and have 80mls till empty but don't like to let the light come on I normaly get between 50-52 litres in

Thanks mate, just call me a Dummy.

No, let me call you a cab instead

THE i30 · **Reply #10: November 20, 2012, 22:34:50**

Yeah it only used 45 litres for the 970km it has a 53 litre tank so still had heaps to go by the gauge it was just under a 1/4 of a tank left.

Lakes · **Reply #11: November 30, 2012, 21:12:20**

Good result!

The fuel gauge is not 100% I've owned two i30 CRDi's from new & both fuel gauges same.
When I filled all the way up to top, just below the 3/4 mark is the true half a tank @ that point if you fill to very top you get 30L in at least I do. But I have ran it too bottom mark never ran out but the most I've managed to get in is just over 58L furthest on one tank for me is 1,320k but could have managed at least 60k more just I always like to use the one servo so filled up. On average it's easy 1,100k for me

AlanHo · **Reply #12: November 30, 2012, 22:57:16**

With my 2012 i30 CRDi the most I have managed to get in the tank on a fill was 60.73 litres.

The biggest range I have got on a tank was 752 miles = 1210 km.

On my previous i30 the most I got into the tank was 58.04 litres

The biggest range on a tank was 621 miles = 999 km

EDIT

Typo correction. 752 was 652

652 miles only equals 1049 Km

(did you mean 752?)

That must have been bitterly disappointing.

It would be like batting for two solid days and getting out on the last ball of the innings for 99.

Well spotted - it was a typo - 752 it is.

I have amended my original post accordingly

I've just ticked over 4000km on mine, and I get an average of 900km highway, and 700km city - although, I haven't got the balls to let it run empty. I always chicken out when it gets to 1/8 full. Usually when i refill, it takes about 43L

At 43 litres you are certainly refilling before it is empty.
Hyundai reckon 53 litres but I've had over 60 litres many times.

SPman · **Reply #18: December 06, 2012, 06:27:24**

Yesterday, showing about 1/8th full, we squeezed in 53 litres, in a CW, so 60l probably sounds about right.

Lester · **Reply #19: December 07, 2012, 00:02:13**

So with the FD Petrol, how many litres of go juice do we have in our tanks then when the fuel warning light comes on?

Does anyone know that equation?

Might I add you blokes (and sheilas) in the CRDI's are getting some magic economy. Lubberly Jubberly.

AlanHo · **Reply #20: December 07, 2012, 08:36:58**

My warning light comes on with 80 miles to empty. It then counts down until it reaches 35 miles when the numbers disappear and are replaced by 00
I got 60.7 litres into my tank after the distance to empty would have read 28 miles (I refuelled 7 miles afer the trip figure changed to zero).

I am not willing to run it any closer in order to refine the figures - I was sweating enough at the time.........

Doggie 1 · **Reply #21: December 07, 2012, 08:43:58**

That is really good info and I have to admit I've never really worked it out.
If you know you have a good 50-60 kms left when the dreaded _ _ _ pops up on the DTE, then that's pretty good.
Once I get to know my car more I'll be a bit more confident in pushing the envelope a bit.

AlanHo · **Reply #22: December 07, 2012, 10:42:24**

I would be concerned if anyone should assume that my figures are gospel for all i30's. I have little doubt that the measuremnt of fuel level in the tank may not be consistent in a particular car or apply to others. I have noticed my fuel light come on when there are 2 bars (Out of 12) still showing on the fuel gauge - but sometimes it waits for only 1 bar to show.

Doggie 1 · **Reply #23: December 07, 2012, 10:43:44**

No worries, AH, all care no responsibility.

AlanHo · **Reply #24: December 08, 2012, 12:44:04**

It so happens that I had to refuel today. The fuel warning light came on with 85 miles to empty with 2 bars showing on the fuel gauge. At 40 miles to empty the fuel gauge showed one bar and at 30 miles to empty the trip distance to empty changed to -- -- and the single bar in the fuel gauge started flashing. I ran the car for a further 16 miles before refuelling (theoretically 14 miles to empty) and managed to squeeze a record 62.3 litres into the tank.

Without boring you with the maths - using the data from this fill indicates the tank plus filler pipe volume is 63 litres.

I also did the maths on the previous fill when I got 60.73 litres into the tank with a distance to empty of 28 miles. This again resulted in the tank plus filler volume working out at 63 litres.

On the previous tank, fuel economy was 57.3 mpg (4.9 l/100km) – distance travelled 752 miles (1210 km)
On this last tank, fuel economy was 52.8 mpg (5.35 l/100km) - distance travelled 710 miles (1140 km)

Brim to brim calculations
There were 3 DPF regenerations for each tank.

I guess the increased fuel consumption can be attributed to the sudden change to really cold weather over the past 3 weeks and a slightly higher proportion of city driving (bloody Christmas shopping!!!)

Doggie 1 · **Reply #25: December 08, 2012, 12:58:42**

Excellent.
So I'' work on 63 litres then and send you the towing bill if I run out.

Lester · **Reply #27: December 09, 2012, 00:03:22**

Excellent work Alan. I have the 'needle' fuel gauge (FD) I would probably get 100 km with the warning light on, but I am one who keeps his car half full, not so much damage at the bowser @ AU$1.55 for unleaded premium 95 which I use.

**Reply #28: December 09, 2012, 19:32:53**

Hi.

How on earth do you achieve these figures? I just run mine for 5000 km and if I do my very best I get around 20 Km/l, but normally I get around 17-18 Km/l. I mostly do around 90 km/h on highway and 130 on freeway's.
But then Again I never top off the tank when I fill it, I think I will do this the NeXT time. Oh it's a 2012 1.6 CRDI

So that is between 5 LPH and 5.5 LPH which is not too bad and should improve as you get more kilometres up....
