This thread is a little old, but I just stumbled across it. I thought it was worth mentioning that I just bought 12qts of 20/50 Mobil 1 V-Twin at Pep Boys for $9.89/qt. They only had 3qts on the shelf, but it only took them a couple days to get more for me.

Rocket Rob recommended Mobil 1 20/50 for V twin 3 yrs ago due to its high zddp and my engines are happy.

I'm running V-Twin in both of my cars. So far so good.

Just switched from M1 V- Twin to Joe Gibbs DT50 (developed for air cooled motors) Better base stock than any Mobil 1 product.
