Oil is an exciting topic on forums, that is for sure! I very much agree that any synthetic oil made in the last 15 years is all excellent stuff, go by the rating required to pick your flavor.
Anyway, I live in hot climate, often hits 45 degrees Celsius everyday for a hundred days a year - 20W oil works pretty well here. Never had the occasion to start a motorcycle when it was below 10 degrees Celsius ever. As an engineer I wonder what would you say of the - relative to other available brands - high phosphorus and zinc content of the Mobile 1 V-Twin oil (for RED BIKES! ) in an older motor with over 30,000 miles that has flat tappets vs rollers?
