Hello I have a 1976 anniversary edition 4108, I rebuilt the engine and installed a cast iron sleeve. And an early 80’s 6211 that I engine swapped an opposed 19.5 hp Briggs into. Both run great and use very little oil. I was just wondering what you guys use for oil. As for me I use Phillips Victory 20-50 aviation oil. It’s my reasoning that they both (piston planes and mowers) are air cooled and run near redline most of the time. Anyone have any other options?
