So what actually is the best small engine oil?

What I use and all my mowers are a few decades old...

I mean if this is the oil they run in 100k top fuel engines making 10,000 hp, it ought to give any air cooled vtwin the ultimate protection. Haven't posted in a while and figured this would be a good starter.

I absolutely love Maxima oils for my motorcycles but for my aircooled engines I have always run a full synthetic 5w-40 or 5w-50 depending on the engine.

My zero turn kawasaki runs hard and hot and I run schaeffers s9000 5w-50 leftover from a motorcycle trial. It didn't shift well, so I stopped using it and had a few gallons leftover.

Generators, power washers, chipper, push mower etc get 5w-40 M1 turbo diesel truck or rotella T6.

For the price I don't think a good HDEO can be beat. I always go with synthetic to help fight coking and sludging from the heat of aircooled engines.

I don't think I have actually purchased or used a conventional oil in decades. No reason when synthetic is only a few dollars more.
