Zinc.....

[mykal41]

Amsoil 15w40 heavy duty + marine with lucas zinc break in additive. Is this a good break in combo? I though I ordered zinc from you with the cam, But I forgot.

Im going to install this week and just want to be prepped.

If it is a used engine this will work but if it is a new engine, synthetic oil and lucas will not allow your rings to seat in the cylinder bore correctly.

I always use Rotella and a bottle of our zinc additive on street cams and two bottles on our radical cams.
