Running 1oz of 2-stroke per gallon of gas will cause the cat to clog and fail more rapidly. Besides 1oz per gallon is overkill for a street car, we run 1oz per gallon in our race cars but that is because we run the cars no less than 7000 rpm during a race. Recommended usage of premix for a full emissions equipped exhaust should be no more than 6 oz per tank. I myself have had to replace my cat because of running 1 oz per gallon...not cheap! As for which kind of 2-stroke to use, I use Redline Racing 2-stroke, Royal Purple 2-stroke is nice too.

To the OP, oil type will always be up for discussion...I alternate between Redline 50WT and 10w40 Castrol Syntec in the summer and 5w30 in the winter...have never had a problem.
