synthetic oil in Onan

[robert m fukumoto]

Has anyone tried or used any synthetic oil in their onan generator? Will
this be beneficial or will it cause problems?

I have not put it in mine yet but plan to do so this weekend. There is no
doubt in my mind that it is cheap insurance and will extend the life of the
motor. I have used it in my cars for many years and could always tell by
the way the engine ran that mobil 1 was in it.

I use Castrol Syntec in my 4.0 Onan. It definitely cranks better and
appears to run cooler and with more power. I also added a flap on the
lower to prevent hot air from recirculating while camped to help with
the cooling.
