Default Post your gas mileage!

Oh my gosh gas was 3.69 for me today!!! (for premium)

So today I actually calculated my gas mileage using my trip/odometer and the amount it took to fill the tank. I was getting 19.58 MPG with mostly city driving and about 6 miles of freeway round trip on the way to work. Oh and BTW I was driving like a GRANDMA. In about 250 miles I gave it more than 50 percent throttle maybe 3 or 4 times.

My car is a 2002 Z28 with a manual transmission. I have the SLP lid and cold air and KandN filter. For exhaust I have long tubes and high flow 3 inch cats and 3 inches out the back with a single exit.

So post your gas mileage because I'm curious! Include your car and what you've done to it and how you were driving if you could please...

I do quite a bit of highway driving. If I drive pretty calmly I get about 270 miles to tank, or go as low as 250 if I drive like I want to. So average of about 18

typically get 18.5 mpg ish (american gallons) so actually not too bad for mainly town driving etc with all mods in sig, maybe including a few full throttle moments

on a motorway run i get upto 26 mpg so im pretty happy, it'll be even more soon when i sort the tune out too, just waiting on my MTX wideband

I average across a tank about 28 MPG in the summer. That is with 85% highway driving. In the winter it falls off to about 26. I used to hit 29-30 across a tank but my high percentage was more like 95%. Stick 3800’s Rule when it comes to mileage

I have gone 350 miles on a tank but I do not like running the car that low on fuel.

Last time I calculated MPG it was driving from VA to PA. So mostly highway I got about 25 MPG. 02 Z28 automatic, only mods are SLP lid/K&N filter and Flowmaster catback. Used cruise control and did only about 5 over the speed limit due to speed traps all over Delaware.
