I got 22.4 MPG on my drive to Indiana in my '85 a couple of weeks ago. Not bad for the old L98 and a 3.33:1 rear end.

A well tuned V8 with a low drag coefficient (believe the C4 is around .32) pays off at modest speeds. My 90 gets better gas mileage at 75mph than my 1973 VW did at 55mph. I like that.
As a note, the C5 (believe the Coefficient of Drag is under .30) typically gets better than 30 miles per gallon. Again, a well tuned V8 with even lower drag.
Nice cars all.
Next time out I will try to stay at the posted speed limit and see what it gets.
Keep the greasy side down.
