I have used Brad Penn SAE30 oil for breaking in the last two engines I've have done. No flat cams
I got the oil from LN Engineering, Super service !!! But I have heard from other "big guys" in the VW
racing world saying that Brad Penn oil is the worst oil ever
Now I am confused..... I will order more
Brad Penn SAE30 oil soon because the cam did'nt go flat even that one of the last engines I made was
equipped with pretty strong valve springs(only outer springs was mounted when breaking in the engine).
Brad Penn oil is cheap in USA, but shipping to Europe is expensive
because it's considerd as
dangerous goods.
