2 stroke oils

Snowmobile oil is designed to stay mixed in colder weather more or less, which is important of course, especially with ethanol containing fuels. Generally speaking it won't or at least should not be harmful to a bike motor. Personally I'm finding high performance synthetics to be the best thing on these funny motors.
 
Snowmobile oil is acceptable.
Injector oil is designed to stay thin at low temps.
I am finding these engines work and survive best with old fashioned castor oil a 24:1, followed by synthetic at 32:1.
Marine 2 stroke oil is the worst to use. No heat tolerance.
