The Stovebolt Site Forums The Shop Area General Truck Talk 7.8 miles/gallon, sound right?

I don't have any idea what kind of mileage I get on my 216 with a 4.57 diff, because the stupid speedo gear in my tranny is shot.

Grandpa claims he'd get as much as 20 out of it, depending upon what he was doing with it and how heavy his foot was. He also says that it averaged around 16-17.

He also says that when the 235 came along they were more expensive to run.

Now, this is from my grandpa, so there's the BS factor to think about.

However, based on its performance thus far, I'm guessing that I get at least 15MPG with my truck, and that's with the carb set a little on the lean side and me not fooling with the advance at all.

7.8 seems a bit low to me.
