Do you run your chain saws, lawn mowers, cheap motorcycles, and string trimmers at max rpm for hours on end? If not then any TCW oil will work. Now, if you were like me and ride an Aprilia RS50 (modded to 80cc) to work then it will be 3 hours at > 12,000rpm per trip. I run Red Line TC 2T oil so I don't have to rebuild it every weekend.
In Europe people ride 2T motorcycles 50-250cc to commute on the highway and some of those motorcycles worth about 200 lawn mowers. You either pay now or pay later.
Many people run 2-cycle, air-cooled leaf blowers at full RPM for hours on end.
I'm not "arguing" anything here, I just want to understand how a product with a well-respected name from a major corporation could make fraudulent claims that could damage or destroy an engine (based on what those here have said).
