..."farmed" Samlon you don't put catsup (or "Ketchup", if you prefer) on?
You can call it snakeoil if you wish: definitely don't use it if you don't believe it works. 100% your choice.
It would seem that others don't necessarily agree, mostly those for whom it has worked. There are certainly ongoing debates about whether an engine that has been run on 100% synthetic for years even needs to be cleaner than it already is... probably.
Debate is good.
The fact remains that many have seen this product work with their own eyes, felt the material loosened and trapped by the oil filter with their own little fingers, and enjoy the benefits (presumed?) of having a cleaner engine. Some have seen elusive seal leaks go away, there is a substantial history of oil analysis, before, during & after.
Don't buy any if you don't think you need it. Don't try any if you don't think it works.
