what is your guys mpgs at? My 94 lt1 seems to only get about 220 miles to a tank and that seems to me to be about 40-50 miles too low.

What octane gasoline are you running? I get about that if I run 89 octane. If I use 91 (that's the highest we have here), I seem to get better.

Under normal driving I get about 20 mpg on a full tank.

My car is bone stock w/ a cutout. LT1 6-spd.

If I'm playing around I get about 16-17 on a tank and my best ever was 25 on a trip.

has your local gas station switched to 10% ethanol blend? if so, you'll notice about 1-1.5 mpg loss. atleast i did and several other people i know.

If your subject is "Mpg's", then give us your MPG, not how many miles you get to a tank.

Well, I get anywhere from 14-24, depending on driving habits. But generally I get about 20, give or take, and that includes a good amount of playing around, and about 75% highway. I have an LT1 M6.
