Quantitative info needed. Considering gas is 2 bucks a gallon and you filled it a little under half, you may have put in 6 gallons if that much. You didnt' tell us how many miles it is to work and how many gallons you put in the car. Have you performed a tune up lately?

what are your mods to your car and how many miles on your motor? When was your last oil and filter change, when were your injectors cleaned? Factory fuel pressure regulator? is it working properly? Do you smell excess gas? When was the last time you changed your fuel filter? Try changing it.

How is your compression? Any CEL? Your O2 sensor could go bad and throw your gas milage way off.

95 Gsr With CTR Pistons and Stage 2 cams and I can go 280 to 300 on a full tank. Sometimes the needle doesn't read accurate don't judge it by that. Mine will move slow then fast then slow around half and then fast to 1/4 and then stay on E for a while. It is wierd but I always clear my mileage to check.

yeah good info right there....

u need to get a new cat and o2, then a tune up, run some injecter cleaner through it, and don't give it hell... also it seems to me u only got about 3 or 4 gallons in it which isn't much..plus u said a 25 min commute one way so thats another 25 back, think about it.

I have a 99 LS just swapped into a 5 spd (Best mod ever), everything else is stock. I fill my baby up Aprox 9 gallons of (87 - Cheapest) and it gives me Aprox 240 miles. is that ok, or is it low? if it is low what could be causing it? Mind you I just had the car tuned-up 2 weeks ago!

Cheers,

last time i filled up, i went 310 miles on a 10 gallon fill up. i'm pushin 180k miles.

About ur car though, u said u filled up a little under the half way mark. I've noticed that the gas needle is not linear, so it goes to E faster from half way than it does going from full to half. do you remember how many gallons you filled up with? and how many miles you might have driven? there might not even be a problem

well lets see, the owner that had it before me had done a tune up in november.
Current mods as for right now are a K&N filter, Exedy St. 1 clutch and 12lbs flywheel. When I got it I did a fuel injection service cleaner, and cleaned out the throttle body with some b12. On sunday i put 10 dollars of gas which down here gas is at 2.24 for premium gas, but i dont really check the gallons and stuff I know i should start keeping count from now on. But damn i can be driving slow and then i punch it for a fun pull and see the gas needle and it goes down Im like wtf. What im thinking is maybe the fuel lines or something i dont know.
