Does chemical composition of oil effect ARX?

[Gebo]

I am trying to choose which conventional oil to use with ARX? I don't want to be too technical but as I look at oil analysis from PQIA I find some major differences in the additive packages.



Havoline is higher in Moly and Mg with a touch of Boron. Mobil 5000 is high in Moly and Calcium. Pennzoil is high in Boron and Sulfur and no Moly. Quaker State is very high in Boron with a slightly high Moly. Note, these numbers are relative comparing Castrol GTX, Exxon, Citgo, Havoline, Kendall, Mobile 5000, Pennsoil Yellow, Quaker State, Shell, and Valvoline.



So, my question is this. Does Boron, Mg, Cal, Moly enhance or inhibit ARX's ability to perform?

during rinse-phase: use a motor oil that is the least polar in composition than that of AutoRx(ester, which is polar) in order to obtain maximum effectiveness.

It's the polarity of AutoRx that attacks/encapsulates the dirt in your engine; and during rinse-phase: a relatively less polar oil will reverse the ester's direction of "pull" into the oil and along it takes the dirt along with it(AutoRx).

That explains the reason why rinse phase of AutoRx typically calls for conventional oil, such as Castrol GTX, etc. to perform the work and not something polar.

additives has little to do with how AutoRx works, so long as it bears little in oil's relative polarity.
