slick 50

[Neil and Lorna]

Anybody use it and if you do what do you think?

I wouldn't put that anywhere near a modern engine. It is unlikely to bring any benefits and "could" void your warranty if something like a blown gasket ever happened.

Personally, I would only consider using it on an old car that was on it's last legs just in case it helped it limp along a little easier.

As Ken says, never ever, never ever use any so called special product on an engine that requires synthetic oil.
All the seals and gaskets in the engine are maunfactured in such a way that there is no reaction to the special oil our Mini's adore
