The "check oil" light came on. I checked the oil after a ride and it was low but above the "Add oil" mark. The next day I started the engine and let it run until I felt hot air coming out of the muffler. Probably 2 minutes. I then started adding oil until it was to the top mark. I guess about 12oz. Next day I want on a ride and checked the oil per the book. WOW. The oil was a half inch above the full mark. I siphoned out the excess - 8oz - and after another ride the oil is right at the full mark. And I found during the siphoning process that I don't like the taste of BMW oil Anyone know how much oil is between the Low and Full marks?
