Recomended oil for Onan 4KW generator
Hi We have an Onan model 4KYFA26100K 4 KW generator in our Class C and were wondering what is the recommended oil type for it? Thanks.

I used to buy nothing but Onamax which then was 15-40..I bought it by the case and have some left over but it is so old that I decided not to use it so I took the bottle down to the parts store and matched the services and got 10-30 which I think Onan is recommending now.
