My 317 manual doesn't mention the Onan P218G replacement engine. I put in SAE30 dino at my baseline change when I got the tractor in May. I want to change the oil to synthetic for winter. What weight oil should I use?

Just changed my oil today on my 455 for winter. 5W-30 synthetic . Expensive but peace of mind.

I don't use synthetic but I do use 5w -30 year round
