Oil for the Onan

I really don't feel like driving to the dealer for Onan OmniMax oil if it is safe to use any other quality motor oil
Sugestions
Synthetic? Blend or just good old Penzoil?
Thanks

Synthetic?
Blend?

I use 10 w 40 Penzoil Platinum full synthetic. But then again, I use synthetic in every piece of equipment that has an engine, and all my vehicles.

Check your book, don't they call for straight 30 weight oil? Can be modified for harsh climates. Any certified oil will work (mfg's)

10-40 synthetic.
Do a yearly pm.
Oil, oil filter, plugs, air filter, fuel filter, clean slip rings if accessible. Always add fuel stabilizer and if you have access use gas without ethanol.

I have read that synthetic in an air cooled engine is not preferred but I run Harley Syn 3 in the air cooled Harley
Would this be a safe option?
There is no way on earth that Genset is working harder than the Bike especially in Southern heat.
But there is obviously a big difference in these two engines
I just don't want to screw something up and then hear,"You should have used Onan OmniMax oil like the manufacturer suggests and now you voided your warranty

You asked the same question in another post also 6 minutes before this one. I think that would be double posting!

Similar posts merged into this one and moved to electrical, charging systems, and solar subforum so the OP may hopefully get their question satisfactorily answered.
