Checking Generator oil question
Hello! I have an onan 5500 gas generator in my motorhome. A question that has always bugged me, when checking oil, when I unscrew cover and look at level it's always lower than when I screw it back on...

My 5500 Onan behaves exactly like Mr. Steve's. Both my 4000 Onans show way overfull when you initially pull the dipstick. Maybe because the 5500 has an oil pump and the 4000s are splash lubed?
