Just a little enthused, my '92 Z28 (LB9, 5 Speed) has always gotten really good gas mileage since I bought it back in february. Well I finally calculated the mileage and got 28 mpg on my last fillup!

This is with about 1/3 street driving and 2/3 highway driving, and yes I stepped on it every now and then too. So 30 mpg is deffinitely possible in this car. Just wanted to share my results!

 

That's really good.

About 5 years ago on a trip to Las Vegas I got 27 going, and 27 on the return. I haven't been able to duplicate it since though, usually get about 24 maybe 25 on the road.

 

that must be nice, highest i ever recorded was 22, with an average of 18on high

 

i have a 87 IROC with the same motor and a 700r4 and on the way back from buying it in tennesse i got 24mpg and after i gave it a tune up i got almost 27.

 

Still havent given this thing a tune up, and I'm sure it could use it.

EDIT: Oh and current mileage: 228,xxx

 

damn, best i have gotten was 16 but that was with 2.73 gears, now i have 3.42 so it will probably be even worse
