Is there any opinion on the effects of non zinc oil on high performance cam wear. I have read that modern motor oils do not offer protection for solid lifter/cam.
Does or has anyone used "Oil Extreme Concentrate" in their motor???? I have read that this product offers the same wear protection as zinc. ![]()
