That's the best time (so far) w/ the mods on the car.

The way it runs on the highway, I am sure it has better than a 12.9 in her, but I'll be damned if I can get the tires to stick well enough in cold weather to prove it vis a vis track times !!

yeah I was talking about per tank, not MPG. Although I went from about 14 mpg to about 20 mpg around town. Haven't figured out freeway mpg.

I have driven once on an all freeway trip and got 24 mpg... why isi that you guys can get so mucm more than us? is the bolt ons and mods you've done... cuz mine is stock except for slp d/d...

Maybe you should try this stuff then. It really helped me. Only cost $9

Yeah mine has only come on when i put the car in acess or when i mash the pedal and shift at redline, will it say check guages. I ddint know it was also a fuel indicator?

But i am due for an oil change so we will see how this works. I use mobile 1 synthetic. Is that what u used when u did this test?

That's 17.7 mpg!

I get 25mpg on mine, 30mpg on the highway. 400 to a tank, I have an 02 so my gas tank holds another gallon or so more though.

Actually I'm getting 20 mpg around town. 270 miles on a 13.5 gallon fill-up. Also, the 98's only had a 15.5 gallon tank. 99 and up has 16.8, another reason you would get more miles out of a tank. I don't do a lot of freeway driving anyway. I was getting like 13 mpg, so I'm REALLY happy now.

that was the average for my LT1 car
