Combined, I'm getting somewhere in the neighborhood of 17.5 - 19.5 mpg.

 

I used to get about 19 miles per gallon, but recently it has dropped down to around 16. This is all city driving (with a HEAVY foot, I love the redline) and very little, if any, highway driving. I'm not sure why it's running a little more rich now, I've had bigger issues to worry about.

Car is a 84 GSLSE, K&N cone filter, RB cat replacement pipe, and a little mild tinkering here and there. Dynoed at 125 RWHP.

The other car...gets 21 to 22 MPG city, or 32 MPG highway. Of course, it's a Miata.

 

I consistently get 26 mpgs on my '82 GSL, when it was stock, and now that it has a custom exhaust.

I did get 34 mpg once, that was an experiment and it wasn't worth it. The experiment was called, "what happens if i don't let my motor go over 1500 rpms" I cruised around at 35ish mph for one tank of gas.

 

i get about 18 or 19 mpg average.
