An item that most miss is that racing oils were designed for people that race. As such, some of those oils do not contain much in the way of detergents because the people that use them get inside their engines on a very frequent basis, taking care of various things in the process. Great lubricants and cooling agents but not the best for long term, unattended use. People serious about their two stroke engines might be getting inside them and making adjustments to components after every run or two.

The average R/C two stroke user will be lucky to see the inside of their engines only once during the entire use and ownership period. Many will never see the inside of their engines. Lazy, fear, short of time, doesn't matter, they don't get involved. They prefer that caring for a mechanical product be an automated process. So there's no one miracle oil that's suitable for everyone. You have to learn something about various products to determine what will work the best for you. However, some oils are pure garbage over the long run, with the long run being more than only a couple hundred hours.
