Yes, I was considering calling/emailing Lake...

I've seen all the oils mentioned above, but I assumed those are brands people would be using, I have used Castrol and Royal Purple personally, but that was long ago and always in a roller application.

As I am considering building a flat tappet motor in the future, I am quite curious about the current issues and how to avoid those problems.

Do these oil companies have specific oils formulated just for the flat tappet motors?
Or do I have to add additives, and then here we go with the amateur chemist act.
