I get ~25 MPG on long trips, even with the 4.10s. Im convinced that my in-town mileage is in the single digits though.

Default Mpg

Hi, when I first bought my 2000SS in December 2001, I was averaging 240-260 a full tank. That's an average of 14.28-15.47 around town. With all of the mods, I'll average 160 full tank which is 9.52 mpg. For our cars to average 20-25 on highway, a full tank would give you 420miles total. The manufactors estimate of total mpg is 374. Somehow, these numbers don't match. The best I got from when my car was fully stock was 320-340 total on driving to California from Las Vegas at around 75-85mph. That's 20.23mpg@16.8, which is our tank size. When I had my 1980 Honda Accord Hatchback, I would get 300 on a full tank@27.77mpg. If you do the numbers, my tank size was 10.8 gallons. Later

Driving habit and tuning does help but also the tranny. My Formula bone stock actually got me 30mpg on a trip from Lafayette, LA to Indy, but I was only going as high as 65mph. City was about 20-22. I haven't recorded the gas mileage on the H/C combo, but I know it got worse. With the 402/F1-R, I will be happy to hit double digits. This TA I just bought with an auto only got me a best of 24-25 on the German highway.

But here is the thing most guys asking these questions are missing. You don't buy a V8 car to get gas mileage in the 30s and if you are modifying you car for more power you are not really worried about gas mileage. I saw a 2mpg drop just changing the gears from 3.42 to 3.73. If you want to play, you got to pay....the oil man.

Hi Gold Phoenix, you got that right("If you want to play, you got to pay"). I just can't get more than 160-175 a tank out of my beast in town. Thanks, Kevin.

I've put 2 tanks of gas through the car on the current mods. I got 17.1mpg the first time, and today got 17.45mpg. And since the mods are new, that's with a lot of playing and 6200+ RPM WOT runs.

so you are saying that you ran your car completely out of gas and then filled up? otherwise your math is skewed. general way to get apprx (very close) mpg is miles, divided by # of gals put into the tank. its not exact, but its very close.

26-27mph...hwy if I do about 72mph the whole way, and in the city I get about 240-250 miles on the odometer before I have to pull in and fill it back up, so city is about 16mpg. IF I don't play alot. If I play its literally like a windshield wiper blade on the gas gauge. Or if I do like 80mph+ on the hwy it also goes very fast.
