28 MPG

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!

Re: 28 MPG

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.

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