You must be one of those young whipper snappers g
I very well remember back in the late 50's early 60's 13 to 14 was not bad
some of the guys in HS were driving chevy's with 4.56:1 and 6.17:1 rear
ends that were lucky to get 6 mpg.

Agreed! Even my 1977 Trans Am only got 8 - 12 mpg when I was driving it.
Of couse at 16, the throttle was either ON or OFF.

Back then the best economy cars were
luck to get 20!
