I have been researching this lately. All sorts of info out there. This is from Toro's website: "The recommended oil for all Toro 2-Cycle snowthrowers is Toro 2-Cycle oil. Acceptable substitutes are: NMMA TCW III or ISO E GD." There seems to be a LOT of great oils. I ran across Royal Purple 2 stroke oil, it's nice but pricey!! I still think the Toro brand is best at least for the initial break in. It may snow tonight! But too warm for it to stick.
