Do you exercise your generator in the winter?

How many of you exercise your generator monthly during the winter? Obviously this only applies to those who have to winterize and store your unit...

I bought my first RV right at the end of the season last year, and figured I'd winterize the engine and generator the same way I've done every other gasoline engine I've owned (including, ironically, generators). Fill the fuel tank, add fuel stabilizer, run for 30 minutes, park it, then pull the batteries to store indoors. In spring, charge and re-install the batteries, start, and run until warm. Never had a problem leaving something sit unused for up to 6 months with this approach.

Now every time I read that generators are supposed to be run every month I feel that I'm not taking proper care of my stuff. Unnecessary cold starts in the dead of winter can't be the best for engine longevity either. What does everyone else do?

  • Yup, once a month, turn on the 1500W heater, the two lights that I have left that haven't been converted to LED, the TV & DVD, put in a movie & occasionally put a bag of popcorn in the microwave, and kick back. The dog loves it. ( Or maybe it's just the popcorn he loves) :B
  • I do what you have always done. 5 years now with onan gen. Run with Sea Foam
    in the fall prior to storing, leave it sit for the whole winter. Have not had
    any problems in the spring with it.

  • No.

    If it's parked in Alaska, it's up near Fkbs and it puts more wear and tear on it in that cold to try and start it every month than it's worth. If it's in the States, it's in storage and a long ways away from me. It's never parked more than three months at a time and while I'm using it, it gets several hours on it every week.
  • I do, I run my with a 1500 watt heater plugged into it to put some load on the generator. I have a 3200W diesel gen so the 1500W heater puts some load on it. I also start the MH and take it for a couple of hour drive up the road and down. I want drive it enough so I can get a regen in if it needs it also, as it is diesel also.
  • Yes, I exercise my generator each month while in storage. Usually run it for 1 1/2 to 2 hours with some kind of a load on it. Have always done this.
  • YEP......
    But my generator is also used as 'back up power' for house (fridge & lights)

    Generators like to be run.....good for stator, good for rotor and keeps carb clear.
  • Yep. Every month. Per the Onan manual they want you to run it w/ some load for 2 hours a month if its not really used at all.

    Which is basically what I have to do since I ONLY really NEED to use it when I'm underway to keep the fridge cold. I always camp w/ full hookups.
