I'm hate to admit this but I've only owned my '01 Mobius for about a month and have already run out of gas once. I'll tell you what I'm doing now. I totally ignore the guage and just keep track of my time. With 5 jerry cans in the tank...I know I'll have 4 to 5 hours of running time. and the 2 1/2 gallon "easy on the ego" emergency can is always stowed away in the back locker.

Hey great participation fellow Moomba owners!! Great site.
