I think I've read every piece there is to read on motor oil and the debate will never cease. Virtually e-folklore now, cannon fodder for all the motorcycle discussion boards. It's like talking about chain lube. There isn't a "best" - only folks' preferences.Anyone read that stuff?
Plain jane dino oil, so long as it meets service grade and viscosity index as prescribed by the OM, will serve most folks just fine. The compulsive changers, racers, special app guys (say, built motors, turbos, etc) and LDR types who extend change intervals might be better served by one of the super-premium full syns, but who really knows for sure.
Day-in, day-out riding, touring, garden variety street flogging, perhaps a trackday once in awhile? I think the last thing you need to worry yourself over is what sort of oil you've got splashing around inside the cases. There simply aren't oil related engine failures to point to as proof one oil should be avoided and another should be embraced.
