If your not racing, or putting the engine under an extreme load for a long period of time and don't mind the smoke, then the stuff your using will be fine. People who aren't "in the know" about two-strokes use the stuff all the time in two-stroke outboards and watercraft. Talk about earning your keep, I doubt I'll ever run the banshee as hard as someone out on the water all day with a jet-ski. Those poor sumbitches hafta work hard to keep movin in the water, and I don't ever see any just blow up causa the oil.
Personally I choose to use Maxima 927, but I've also got over $2000 invested in my motor and don't want something as piddly as oil ruining my motor. If I had a stocker and didn't do anything but trail ride with an occasional friendly drag race, it wouldn't bother me a bit to use cheaper oils.
I know a lot of people that use Castrol 2 cycle oil, yes, the lawn mower shit (even gots a lawn mower on the bottle) and their bikes run just as good and last just as long as anyone elses.
Damn, im gonna get bashed for this.
