We highly recommend Valvoline VR1 or an oil with a similar zinc content. Adding a zinc additive to your oil is not the same thing. Proof of using high zinc oil is required for all warranty claims.
Note: Cores with damaged shafts or bearing housings may not be eligible for core refund. To avoid $400 core charge simply ship your turbo in advance, with wastegate actuator installed. Core Return Form required for credit. See Core Notes.
