.... and if you really care about your engine, add a small amount of RedLine Break-in Additive to your mix. It contains zinc, and phosphates that greatly enhance wear charcateristics and works like having castor oil in that it thoroughly coats and 'sticks' to the mating components and creates a very good boundary layer between the two parts - much more so than straight 2 stroke sythentic can & will alone. Use it at least until you use up the first bottle of it, then maybe once in a while thereafter. Kind of like when you buy a new car - and you would traditionally run it on a castor based oil, then switch to synthetic after a certain mileage.
