@Road_Clam I meant no disrespect for your experience. I am relating what lubrication companies have told me for a very long time. I know nothing about motorcycles - I just use machines that have lasted a long time without (much) wear. Frankly, any oil is better than none, clean is better than dirty, and getting the perfect match for a lubricant comes after these....
I have talked with lube guys a lot, as I've heard a lot of guys talk about different lubrication strategies with polar opposite opinions, so then I call up Shell or Exxon and talk to one of their lube specialists to get a clarification...
