Quick question about oil changes

I have 2015 Winnie on E350 chassis. We live in southern California and only use our RV 2-3 times a year. We drive a total of less than 500 miles a year.

Question is: is it ok to replace oil every 3-4 years? I know some people think oil needs to change periodically regardless of how many miles you drive, but I don't see any differences whether oil is stored in my truck or in the bottle on the store's shelf waiting to be sold. There are many "rumors" "suggestions" and "theories" about oil. Any scientific evident that says we need to change oil even if we don't drive?

    Just a question mind you. IF the oil is sealed in the engine, with no leaks, and no way to get air in. Does it still condensate?
  • Use synthetic oil. It will not break down over time.
