i recently fill my tank up and i got 250 mpg mostly city and about 20 percent highway is that about normal?? its a 92 ls

 

Stock '96 GSR and I get 30mpg. half and half as far as city and highway.

 

250 mpg?

Assuming you mean 250 miles to the tank, that seems rather low. You should be around 350-400 miles per tank. Have the spark plugs, spark plug wires, distributor cap/rotor, fuel filter, and air filter been replaced at the proper scheduled intervals?

 

I get about 320 miles to a tank. almost all city.

 

Yea, I was getting close to 350 on my GS-R before mods. Now im around 275, heavily modded.

 

26-27 MPG on a 2000 stock gsr

 

I have a 99 GS-R and I get about 270-280 on a full tank not driving hard on half city half highway. If I drive it hard on vtec on most of the tank ill bearly reach 200 maybe.

 

yeah i changed the spark plugs and wires but i also have a 2000 ls head i dont know if that makes a difference. and how do you know when to change your fuel filter?

 

I think i get around 250 miles per tank. Not changing the spark plug wires or distributer might have something to do with it. Injectors seem to have rust on the outside of them, maybe its time to really deep clean since i assume the inside is fairly gunked up too.

 

I got around 19mpg when I had my Integra, it also had about 190k on the clock. That thing ate gas worse than my mother's Explorer.
