I use this stuff with flat tappet cams....with any oil you want to use.

I just ordered a 3 pack off of ebay. I'm going to try this in my other Duster. I have VR-1 10w-30 in one of my Dusters.

Just a side note, I use Lucas break-in (high Zinc) oil additive when I break in a new cam. It's 18 bucks, but I feel good breaking in a new cam with it......
