I think the aftermarket ZDDP Plus additive is cheaper. Also, it may be less expensive to just use and oil like Brad Penn Racing Oil that has the zinc in it, if you have it available to you. Check with your local machine shops or engine builders.

Yeah, I hear ya on the race oil. I was limited due to time and some other factors or I would have.

I hadn't bought the stuff in a while but I swear last time I got some it was around $10. For $26 I thought the guy would drive over and pour it in for me!
