Average MPG for a '77?
Any 1977 owners test their miles per gallon, or know what it should average. I'm getting 16 mpg in combination highway and city driving. I don't know whether that's right, or really low (meaning I need an engine adjustment).
Thanks.

I know this probably won't help you much, but my '81 gets about 20-22 mpg average city/highway miles. I also run with premium gas though. I don't know if it would make a huge difference, but I have always heard that you should always run Vettes with at least mid-grade gas or better. Better for the engine, and better mpg.

Re: Average MPG for a '77?
I have a 72 350/4 sp/3:36 and since Lars rebuilt my carb and distributor, my first two tanks of gas averaged almost 16 MPG city driving. I expect highway driving will yield 18-20 MPG. I am so happy with Lar's rebuild.

Re: Average MPG for a '77? (RickP)
With typically an 80%/20% mix of highway/town driving on 87 octane, I average between 15 and 16 MPG.
Sounds like you're right where you should be without any engine mods.
FWIW, Motor Trend Magazine averaged 16.6 on their test track for their 1976 review of the '77 Corvette.
