What is the best oil for a Honda 160cc OHC engine on a lawnmower? The owner's manual says to use 10W30 oil although 30 weight oil can also be used. The oil that came with the lawnmower was some forgettable cheap oil in a 20 ounce container (SB rated I think).
I heard a story somewhere that synthetic oil is not recommended for these Honda engines. I have been using Valvoline 10W30 and 30 weight oil. I changed the oil today. I could not find 30 weight Valvoline so I used Castrol 30 weight.
