RE: Two Cycle Oil for Air Cooled Engines
There are two specifications for two stroke oil. One is for low temperature applications, specifically outboard marine engines (TCW-3) and the other is for higher temperature-high performance applications(API-TC or JASO). The term synthetic is just for markerting and generally has little value. All of these types have proven to work well in model engines so it makes little difference what you choose. One thing is for sure, whatever oil that Im using is the very best and nothing else will work.
