I used to have a ‘66 GTO, and I sometimes managed to get 20+ MPG on the highway.
I also managed to get 10 MPG on the highway, too, if I was really getting after it.
My brother left me his 1974 Cadillac Sedan de Ville. THERE was a car, 6,000 pounds of Detroit steel, 500 Cu inch engine, 8 city, 11 highway. You could actually see the gas gague needle move down on the highway. Man, was it safe. Once I month I had to scrape the Corollas and Hundais out of the wheel wells. It was so big I had to look through the steering wheel to see. I miss it.
