I would go FULL SYNTHETIC for the price difference between a FULL and a SEMI-Synthetic lubricant.
My personal preference is ASMSOIL. Have been using it in everything I own/have owned with "0" problems.
I presently have AMSOIL in my following items since new:
1979 Gilson Snow Blower - Model 5148 (Engine, Geer Box, Tranny) (Bought from original owner who never used it)
