Okay, so I’m reading about oils in Snowbum’s discussion about oils for Airheads and he lists popular brands with Zinc and Phosphorus and their ppm ratings. And low and behold in the list is Mobil 1 20/50w for V twins with 1600 ppm Phosphorus and 1750 ppm Zinc, with an official rating SJ. Which is what I have been running in my 2001 Harley Electraglide and 1999 Harley Sportster 1200 engines for the last 21 years with no problems. It would be handy if I could run Mobil 1 for V twins in my 1986 BMW R80RT that I acquired from a friend last summer.
So I’m guessing that Snowbum lists this oil because it is okay to use in airhead BMW engines. I have run it in my Harleys which are aircooled engines hauling me, my wife and our gear on the Electraglide which adds up to almost 1000 pounds including the bike, going 80 mph on our highways in Wyoming including mountain passes, and the bike has never missed a beat. Why wouldn’t it work in a boxer twin? Does anyone else use Mobil 1 for V twins in their airhead Beemer? Thanks Bill
