"AMSOIL is the Best Lubricant made, the standard to which all others are judged."

During AMSOIL's 30th anniversary convention in the summer of 2003, Bobby Unser got up on stage and told about how his race car differentials could not survive more than one race up Pikes Peak without needing to be rebuilt, until he started using AMSOIL. Then his differentials went all race season without needing to be rebuilt. This experience in Bobby's early years of racing began his long relationship with AMSOIL in all his race cars.

Bobby went on to say that: "AMSOIL is the Best Lubricant made, the Standard to which all others are judged." states Bobby Unser three time Indy 500 Winner, 35 overall Indy Car wins, & 13-time Pikes Peak Hill Climb Winner.

Bobby Unser explained to us recently how AMSOIL was responsible for the complete absence in gear box related failures. "When you walked in the garage you may have seen a container labeled as Valvoline, Texaco or whoever the sponsor was but that's not what was in the bottle, It was AMSOIL" - Bobby Unser Sr in the new "A.J. Amatuzio - An American Success Story (the 1.5 hour film on the history of AMSOIL). "Every single synthetic oil company today copied AMSOIL! They Copied AMSOIL! But they will never have the quality and performance AMSOIL has because they can't" - Bobby Unser Sr.
