What I found that got me the best mileage on the interstate, and didn't p.o. too many people, was to run rather quickly up to 81 mph (dash gauge showed 17 mpg @ a steady 81 mph) then back off the pedal just slightly (dash gauge showing 69-99 mpg) and let the car slow to about 62-65 mph and repeat. I bought the car new for my then gf and the mileage and performance just got better as miles were put on it. Sold it in 91 after we split, but I still have the 87 305 tpi Firebird Formula I had bought her earlier, but I never checked mileage on that one.
