Cummins onan oil change
I have brand new toy hauler with new Cummins onan 4000. Is the first oil change at 25 hours then every 100 hrs thereafter?

If this really is a "brand new" RV, there should be an owners manual for the generator in there somewhere. If not, see your dealer.
I think both my Onan's have had a 150 hour service interval.
