Brad Penn has the correct amount of zinc and is cheaper than using an additive.




Not even close, Lucas $15, 3 servings per container, so it works out to $5/oil extra per change.

Try to find Brad Penn for less than $7/qt not including shipping.




I get it for $6 a quart at a local Penn dealer here in the Great White North. Should be cheaper in the US.
