Hhen I don't beat on it, I usually get around an average of 22.5 mpg with half highway and half back road driving. However, when I beat on it for the ladies and all that stuff, I've gotten it down to 15 mpg. My Father has got it up to 29 mpg with all highway driving, but he was really feathering the gas the entire trip. Oh yea, I have the T56 by the way. It's all in the way you drive. Starting in 2nd and skipping to 4th or 5th (depending on the road grade) works best for me on saving gas.

Ive come to notice that unless your a freqeunt Highway driver your not going to get to good of MPG with an LT1 period. I garuntee if everyone on this forum with an LT1 posted about MPG it would average 12-17 MPG thats it for town.

I'm getting 180-200 miles on a full tank in my '97 T/A. Hardly any freeway driving though. I hate how fast the guage goes down after half tank!!

that's pretty much what i get. I dont' take long enough highway trips to see what my highway mpg is. Well I do sometimes, but there's always morons on the highway that cause me to use excessive gas pedal

Before mine got tore down, with the M6 and stock 3.42 gear I was getting 22-23 mixed driving with about 300+ miles out of a tank. Only mods were CAI, shorties, Flowmaster muffler, no cat, MSD Digital 6. Now 12 all highway is about as good as it gets.
