I've always been using Castrol 4T, Yamaha lube 4T, Havoline 4T and other convention motorcycle oil. Since the price of the M 1 15w50 $2 a qts at AZ, I may try. Before doing so, I want to see if others have used this oil on an air cool cruiser and works ok.......I know it does not have JASO certification.
