cure in a can
Back in the early 80's I've used Slick50 as per advertised, looking back didn't really make any difference,especially now Synthetic oil.
It's Big Business, if people want to try them go ahead! But don't dxpect a drastic change or a perceived advantage of extra protection!
I am not an engineer, just talking from experience.. Now if Porsche recommends and back them up, then this will Totally be a new discussion and I'll leave it at that.
