Which Model 5500 do you have? 5.5HGJAB, or the older 5.5BGM? Both have low oil pressure cut off switches. If you have later model (HGJAB) you can use the status light in start-stop switch to help diagnose. Anytime set shuts down and you did not push stop switch, it should give a fault code (series of light flashes) to tell what system is malfunctioning. Also, Onan oil filter P/N is 122-0836. Napa can cross ref. if you dont have Onan supplier near-by. Factory ships units with 15w-40 oil, and works well if your climate is warmer than Alaska North Slope
