Just for what it's worth -- I was in Wally World yesterday and came across this oil for Motorcycles. It was by "Quicksilver" and located in the boating section by their 2-cycle outboard oils. I believe "Quicksilver" used to be associated with Mercury Marine and made very good quality stuff. This is full synthetic 20-50 for big V-Twin Motorcycles. I am not endorsing this but just putting the info out as I had never seen it before yesterday. Price at WM was 7.95 per qt. On another shelf was the Mobil 1 V Twin for 9.95 per qt.
