NiceA few people here have contacted Castrol directly and asked if they still get the “intelligent” Magnatec molecules if they buy the higher tier Edge product. Castrol always comes back with a solid yes, Edge in a similar grade has all the good Magnatec stuff plus some extra Edge only stuff (their fluid strength technology - whatever that is, it doesn’t generate nearly as many threads).
Bottom line, Magnatec isn’t the “best” oil in the world for every application, but it is probably one of the best bang-for-your-buck oils that most of us can easily find and afford.
