Re: Ran out of gas for the first time....
It may be pointless to talk about miles per tank because there are 4 sizes that are popular now. Somewhat under half gallon, half gallon, 3/4 gallon, and full gallon (rarer).
Better to know what tank you have and talk about MPG.
I get about 110mpg and after leaning out to the danger point on recent trip (gray plug) almost double that. 50:1 BTW.
