Marks RV Mailbox - RVs Sitting Idle

Question:  When we are not using our RV, this could be for several months at a time, should I start the engine every week or so?

Mark’s Answer: I always add a fuel preservative to the fuel tank when our unit will sit idle for more than a couple months at a time. I run the engine and the generator long enough for the preservative to get through the fuel system. But, I still think it’s good to start and run the engine and generator at least monthly when in storage. It allows the oil to lubricate the dry components of the engine. When you run the generator be sure and run it with at least a half rated load on and if try to run it for at least an hour. You should be able to find the load ratings in the generator owners manual.

Happy RV Learning,

  1. What do you suggest for an RV stored inside for up to 6 months, where the engine/ gennie cannot be run?

    1. I would recommend using a marine fogging oil if it is not a diesel engine. Fogging oil is designed to protect internal engine components for long storing periods. Make sure you follow the directions listed on the fogging oil.
