Things to consider before purchasing

Before buying an Onan 4000 Generator Oil Change Kit, here are some factors you should consider:

  • Your usage: If you use your RV and generator frequently, it’s recommended to change the oil every 100-150 hours or at least once a year. For occasional use, an annual oil change is sufficient.

  3. Determine where to add new oil: Locate the fill cap on top of your generator’s crankcase. Remove it so you can pour in new oil later.
  4. Determine where to replace old filter with new one:
