Anybody use Slick50 oil treatment? I've heard it coats cylinder & other high friction areas & good for high mileage cars. Put Royal Purple 5w-30 in this week & SLICK50 does make a formula for synthetic oil users I could add. I recall putting this in my cars about 10 yrs ago (don't have them now).

What about their ATF SLICK50 product? Also for high mileage cars.

Fuel System Forumula? Supposed to clean deposits.

My VX has 64k miles and I have no service history records on it.
