i've been reading about fuel varnishing, a gummy build up in the generator when the gasoline in the motor home engine sits for a long period of time. The manual says it can happen in as little as 30 days, and that you should run a tank of gas through your motor home each month. Yikes! I'm still working so I won't be out in the motorhome every month. Do you all run a tank of gas through your motor home every month? If I have to, then of course I will.
The manual also says, "one way to prevent fuel varnishing is to treat the contents of the tank supplying fuel to the generator with a fuel preservative and to exercise the set. Cummins Power TM Generation has developed a fuel preservative and stabilizer, OnaFresh, specifically formulated for Cummins Onan generators. We recommend adding this preservative to the fuel, especially on infrequently used RVs." Do any of you use a fuel preservative and stabilizer?
