Re: ZINC IN OIL & ZINC ADDITIVES
I thought that they had taken much or most of the Zinc out of the Rotella?

Re: ZINC IN OIL & ZINC ADDITIVES
I buy the Zink additive from Edelbrock and throw it in with my Valvoline 20W-50.
I just order a few bottles from Summit so they are here ready for my Oil Changes for my classics.
