I hear that. Seems to happen that way to me too. Of course I think I only get 50mi or so out of 1/2 gal for some reason.In riding my bike, I find that 20-30 miles go past before I know it. I have run my 1/2 gallon tank out a few times by mistake because I'm enjoying riding and dont realize just how far Ive travelled since last fill. Luckily the few times I ran out I was within a mile of home and managed to make it back home easily.
