man mine is slow to 1/2 too and then divebombs... the damn fuel light comes on a little under 1/2!! Cant trust it! :director:

https://www.nopistons.com/forums/pub...IR#>/blush.png By the way, I always fill, and rely on the trip to calculate how much gas I have left, and the gauge of course, cant be to safe when you put as little mileage on the car as I do ( 2000 miles last year )

oh good i thought i was the only one getting ultra $h*tty mpg. full tank is like 180 miles. 16 gallon tank? barely 10mpg. but yea its really quick to half. my tanks reads 1/2 after only like 60 miles. i thought i was getting 120 per fill up and got REALLY scared. but it slowed down. maybe im driving like crap? what is most efficent way to drive/shift? always below 3k? hey what if i went rite into 4th after 10mph? i mean i dont accelarate fast, but im only using like 800rpm. hehe.

I dont evenpush my hard right now. I keep it at 3 grand and shift. And thats the kind of shitty gas mileage i get.

My friend once had his fuel pressure regulator go bad, and it was holding way too much fuel. If there aren't any leaks then it's got to have something to do with the regulator, pump, injectors, etc. If the motor has low compression then it's possible to get poor gas mileage. One time the wire on my O2 sensor was coming loose, and after I fixed it the car ran better. Are you SURE there aren't any leaks? You may have a leak in a hose under the car.

I ended up gettig about 265 miles out of my full tank. That is really good for my car.

I shift between 4k and 7k depending. Never before 4k. and I am getting 21mpg. I would definitely try the easy stuff. O2 sensor can get you really poor mileage. Plugs, wires, fuel filter. All the normal stuff.

I was always getting 19 mpg average and 23 mpg on a long road trip before I remove my cat (it was partially clogged). Last weekend I went on a long trip 1100 miles and I got 27 mpg, it means about 350 miles for a tank. :thumbs-up: I always shift between 4k and 6k, I shift down as soon as I need to accelarate when it is under 3k. https://www.nopistons.com/forums/pub...IR#>/happy.png

ok today i was on empty and my trip odometer read 220 miles to a full tank of 87 octane gas. my car is the 88 gxl. the car isnt even turbo!!!!! my gas milage sucks ass,i havnt repleced the o2 sensor yet or the fuel filter yet,i need some more money. i have the racing beat down pipe and presilencer which i havnt installed yet,(i work way to much,lol im still in hish school on y 14 more days and i done forever!!!!! just thought id share that) anyways i should get about 300 miles to a tank and i completely checked the car for any gas leaks and theres none, so the fuel pressure reg could also cause bad gas mialge? gonna have to replace that too. i do not push this car hard it only has 70,00 miles on it now and its gotta last me 2 years thorugh college! ive raced a couple people but im done doing that until i have some $$$$$ to fix crap in case i break something. i always shift at 4 - 6 grand. 220 miles to a full tank is not good espeacially for being stock!!!!! help!!!!!!! https://www.nopistons.com/forums/pub...IR#>/mecry.gif









waste ricers,all of them!!!!!!!!!!!!!!! god damn it feels to do drive a 7!!!!!!!! legends and sevens never die, rotaries dont get whipped like piston crap!!!!!!!!!!!! die piston motors, die die die die die die die....................yeah im really tired right now. piece

220 miles is not too bad, almost 14 mpg. If I fill up my tank, and just do a lot of city driving I'm lucky to get 200 miles out of a full tank. Last night I put $5 of gas in my vert (87 oct. @ $1.35 a gal.) I've put 24 miles on my car, and need to get gas before I go to work tomorrow. But most of that 24 miles was with my foot into it, and that burnout didn't help. :teufel:
