ZDDP Plus Oil Additive 4 fl. oz

Product Review (submitted on January 12, 2010):

With the higher working tappet pressures of high compression '60s - '70s engines and cam profiles on non-roller cams and the Feds removing or radically reducing this from all modern oil due to CAT and EPA/CAFE concerns I have wipped out more then one cam due to this problem. Even Rotilla has dropped levels of Zinc Disolphate to marginal levels at best. Add a bottle of this to your oil change and rest assured it will have enough ZDP to eliminate cam and lifter scuffing. Great product, thanks for offering it!
