Has anyone had any experience of SLICK 50 oil treatment? Meant to be very good but wondered if there was real a benefit?

apparently, I have heard that people swear by it. I just don't understand why you would need to add an additive to your oil. I would rather spend the money on synthetic oil instead.

The magic ingredient in Slick 50, Liquid Ring, Matrix, QM1 and T-Plus from K-Mart is Polytetrafluoroethylene. Don't try to pronounce it: call it PTFE.
PTFE is a solid which is added to engine oil and coats the moving parts of the engine.
However, such solids seem even more inclined to coat non-moving parts, like oil passages and filters. After all, if it can build up under the pressures and friction exerted on a cylinder wall, then it stands to reason it should build up even better in places with low pressures and virtually no friction.
This conclusion seems to be borne out by tests on oil additives containing PTFE conducted by the NASA Lewis Research Center, which said in their report, "In the types of bearing surface contact we have looked at, we have seen no benefit. In some cases we have seen detrimental effect. The solids in the oil tend to accumulate at inlets and act as a dam, which simply blocks the oil from entering. Instead of helping, it is actually depriving parts of lubricant".

Jus. Many thanks for the good post - will not be using Slick 50! Like so many things - if it seems too good to be true, etc, etc. Will stick (excuse the pun) to synthetic oil.

you simply can't beat a quality oil change and clean filter
