No, getting a little better than that since I never fill my tank. I always leave a little room at the top. Old habbit from my chopper that would leak out of the cap breather if I filled it too far. I get right about 50mpg. 3 gallons more or less at fill up.

I learned all I need to know about life by killing smart people and eating their brains.
