Used Cummins Diesel Questions
Thinking about buying an older motorhome (100K miles or less) with Cummins but not sure something(engine) won't be masked at purchase to be a problem after writing the check. Internet sites list a lot...

For those of you that put 4-5K miles a year on your Cummins DPs, do you change oil every 2-3 years, or annually? Does it hut a Diesel to sit over a winter with 4-5K miles on it when it can go 20K between oil changes? Thx, Jeff
OK I change the oil every year with around the same mileage as you are forecasting (I have around 55K miles on a used unit). It sits from around October to May over the winter (I do not start it or run the generator during this time) plugged into a 30 amp service and check the batteries on a regular basis (now). I also add an additive to keep the fuel from gelling in cold (up to -40 F/C the same at this point) in case I need to use it during the winter.
I don't think I need to change the oil this often but I bought an extended warranty and want to ensure that I comply with the recommended intervals in case something does go wrong.
