Average highway fuel econy of a Fiero

[Here4u2hate]

I have a 1985 Fiero SE with an Iron Duke in it. Im looking to drive it on about a 800 mile trip soon just wondering what kind of gas mileage I can expect to see out of her?

If it is tuned and running good you should get around 28 mpg with an auto trans and around 30-32 with the 5-spd manual typically. Of course the mileage/wear/tune of the engine will affect the mileage.
