The "NOT SO GOOD" gas mileage thread

[Supra-Man18]

Yes the title states all.. Anyone else on here getting less than 175 miles per tank ! I got 145 miles to my whole tank the other day :aigo: This is kickin my ass. And thats Not drivin like an ass 24/7 either lol

 

[TLDriver]

hmm lucky! I am getting about 12 mpgs on decent driving. Well it's in the truck because my differential is shot on my SC300.

 

[tlo86]

hrm i got way better mileage thats for sure.

 

[GotTurbos?]

I also have always got shitty gas mileage. My friend with almost the same setup got like 27mpg and I am fully tuned getting like 19, I don't get it. I did get 23 once, oddly enough it was on the caravan to 2k9 where we were all cruising about about 90. I guess thats the sweet spot for my car lol.

Damn guys. Are any of you running widebands to see what A/Fs you're pulling? I know I was getting 20 city, 24mpg highway before I dicked around with my A/Fs and leaned it out and now I'm getting 24city/26highway

Also depends on how much boost you're running. More boost/air requires more fuel. I have great gas mileage when I had the twins boosting not more than 11psi but with single and boosting 18-22psi the gas mileage is way different.

Damnit.. lol Why the hell is my 1j so thirsty !!

I get about 16mpg in the city and about 22 mpg on the highway. This is driving nicely. Spirited driving I am usually getting around 12-13mpg.

This is with a 1JZ, big single, cams, 22psi, 500whp ect.

 

[OneJArpus]

i get 140 to 150 at half a tank.

Weird part is when i dropped the tank and install the FP it was bone dry. When i put 1 gal in and filled up it only went to 13/14 gallons total. Not 18.5, i get about 20 MPG roughly.

 

[WeDgE]

Crazy.

With my 7M and T78 I would get ~28-29mpg on the highway. Big turbo = easier to stay out of boost.

 

[foreverpsycotic]

With my stock twins, I used to get ~14, but was hardly out of boost unless cruising.

 

[SupraMario]

I got 350+ a tank driving to Alabama a month after the car was finished. Stock Twins 2jzgte.

 

[Supra-Man18]
