RE: Synthetic or Mineral Oil
Sam Adams Alpine Spring.... you gotta try it before it goes out of season...
iv'e broke in 3 DLE engines synthetic all the way... Stihl Ultra HP..... the DLE 55 i broke it in on my "everyday use" oil ratio 40:1
my 20cc and 30cc i broke in at 28:1 Stihl Ultra and have switched them over to the 40:1.... it beats haveing to carry one more gas can around
i have a buddy who breaks in all his engines on Amsoil 80:1 even his DLE30 [X(].... now thats extreme.... when i was young, i did the lawn girl/amsoil thing... i ruined a motor on a lean run at 80:1...
