I am gonna take it in for a tune soon and was wondering what I could do to get even better fuel economy. Is it just the 02 sensor that you need to replace to get better fuel econ? I have never replaced the 02 sensor so I was wondering if it would be worth it.. I can get around 12 litres/100kms now I was hoping to better it.

That fuel consumption sounds about right, I can only get below that on very long highway trips.

Yeah. My best was just under 12 I think. That was half highway half city. Do you think the 02 sensor thing is alright tho like worth the money?

It sounds like everything is okay, prolly not worth it.

what is the best way to test it, just clock your k's and then divide it by the L's you put in next time until full at the bowser?

damm 12L per 100k damm thats bout 500 a tank right damm, before i got my engine rebuilt i was lucky i mean very lucky to get 270 froma full tank of 60L now afters its been rebuilt i only get 360 outta full 60L i have a auto N/A and was wondering if anyone has anyideas why this is? Hoon

Around the city absolutly caining the car I will get around 400km's from a tank, and on the highway I have got well over 600km's, atm I am averaging 500, thats half highway with aircon on full and half city caining it.

Hoon Mine used to only get just over 300kms per tank. I got it fully serviced and tuned, ran optimax with injector cleaner through it a few times and now its pretty good on fuel. To test my kms/L I let the tank run really empty like so I'd only have a few more kms in her then put $10 in ( about 12/13 litres) then kept driving till it was really empty again then looked at the kms. I got 102 kms the first time (mostly city) then 114 kms the second time. ATM I have $25 in her and I'm up to 200 km mark and I recon I can get about another 60 kms out her easy.

i get 11.2 litres/100km(or about 9kms/litre) but thats in a manual running optimax.

I am currently getting 400k's Suburbia/city driving outta my CALAIS N/A runnign either Optimax or BP Ultimate Car has 220,000k's Some original photos have not been recovered yet.

well my engine is completly rebuilt running ultimate and still only gettin around 30k the injectors have been cloeaned and serviced no probs there the only thing i can think off is the o2 sensor or something like that. Hoon

Yeah sounds like o2. im gonna replace mine soon. I ll let ya know how it goes.

Why did you use injector cleaner if you are using optimax?? Optimax cleans your injectors... Quote: Mine used to only get just over 300kms per tank.

Well now they r really clean aint they Some original photos have not been recovered yet.

I replaced my leads and plugs, air filter oil filter and oil. Drove from Brisbane to Byron Bay and back on half a tank. I know soulds like codswallop but dats what the guage says. Now my guage only works when it wants to.. does that mean i need a new tank?

Ummm when you guys test your fuel economy it sounds like you drive it too hard...I usually get MORE than 550 km out of a tank...the best figures I ever got was 8.6 L per 100 km.

FastEHHolden ,Thats Xcellent Fuel Economy dude ,I am only getting 400k's outta my Calais N/A and thats not even caining it Some original photos have not been recovered yet.

I asked this is another section with no answer. I got 312 from 29lt's on the way to xmas holidays filled up then got 560 from 49lts on way back, not the same way of course, and i've done 490 on 53lt since then around town work and back. that's with the S/C fitted manual trans no A/C and heaps of **** in the car.

Just got my car serviced/tuned. Had to get a new fan clutch, fuel filter and oil filter. Before Service/tuning I was getting 450-500k's per tank Now I am getting 600-700k's per tank. I am not driving like a granma, I give it the workout it needs. lol Kingy
