Overall Assessment

Customers highly recommend our product for its proven effectiveness in extending the life of camshafts and its top-notch formulation from a respected company. They praise the additive's functionality, particularly for breaking in new engines and maintaining small block Chevy motors. Reviews affirm it as indispensable for every oil change and superior to other offerings on the market. It's noted for its great quality and excellent pricing. It's the go-to choice for bringing back the zinc into non-roller engines, which is seen as a clear advantage over competitors.

This product should be used in all non-roller engines

Use it when installing a cam or breaking in a new engine with new cam, then add new bottle with each oil change. They made the oil manufacturers take out the zinc. You put the zinc back in!
