I use this in my Onan 5500, have been for the past 10 years in both generators. (from my previous Class C) . Hummin along. I also replace the fuel filter ever other year. I drop the oil every 50 hours and the filter at 100. (every other change) I was told it is very good oil, has lots of detergents in it to keep the engine running clean. I also use it in all my lawnmowers, etc at home too.
