Thanks. You could have just said MoleKule's post was in this thread.

You have to remember, as others have said, that ther are components in a synthetc oi that are polar and may interfere with the ARX esters. For example, in Mobil 1, they use Alkylated Naphthalenes, along with a small amout of ester, as "polar solvents," in addition to PAO. In Redline, the POE's would interfere as well. Same way with Amsoil and other full synthetics.
If the base oil contained only PAO, then there wouldn't be a problem, but as stated above, there are no PAO only PCMOs or HDEOs.
Per this, no PAO oil is suitable for an A-Rx treatment. On the other hand it is commonly accepted lore that the small maintenance dose will be effective with any PAO.

So follow directions and use a GroupI,II, or III oil for the ARX Cleaning/Rinsing regimen.
This implies that Group II and Group III oil never contain any PAO, or at least not any PAO with "polar components," and means that All Group II and Group III oils are, without exception, usable with the full benefit of A-Rx.
