Some detractors will say auto oil containing moly will cause slip in the primary. Mobile 1 15W50 oil does not contain nearly enough moly to cause this to happen, and can be used in all three holes of your Harley Davidson with superior performance. Word of warning - Some service managers may use this as an excuse to void your warranty, so if your Harley is under warranty it is probably best to simply use Mobile 1 V-Twin 20W50.
