What mileage does your slant six powered ride get?

Not sure what you are saying. What do you agree with and what do you think I'm lying about?
Not everyone drives the same. or have the same road conditions. i drive 160 miles a day.just bought a 76 dartlite. i'm testing these theories. owner claimed 30+ mpgs.
Not doing anything to the car 1 st. trip was 28 mpgs at a steady 1900 rpms. i will do a tread soon. all the adjustments tire pressure, size,etc.. to see what i can achieve.
Not all cars are the same either. owned 12 neons, 2 got 36 mpgs others Not so much. same motors. go figure!
