I started with Husky XP oil. I’ve been running the Lucas FD 2-cycle oil in my saws the last 3 years. Only one is a modern auto-tune saw. So far (knock on wood), no problems. But when I look at the insides, they are getting black build up, and they do seem dry.
I have some Amsoil Saber, but don’t trust their 100:1 ratio suggestion.
I would like to have something that actually keeps the inside clean, and keeps a saw running for years, so I’m going to seriously consider the Schaeffer’s 7000 based on Scott’s advice. Even though it’s rated for water cooled engines and Ben just explained why that isn’t ideal for air cooled OPE.
I do wonder if it would be weird to blend my own oil? With some Schaeffers 7000 for its cleaning ability, and some K2, Motul 8000, or Yamalube for the ester oil protection.
