oh, now i got ur point liao...I'm afraid that the tufoil will break the chemical bonds in the ester base oil and make it less effective than before adding. That's what troubling me. Else, I won't have an issue with it.
from wat i know, Ester is an additive for add more protection &
Lubrication in Base Oil. most of branded engine oil will add some additive into it. thats why most branded engine oil so good & so expensive. it won't break the bond, but if in theory, it will well mixed into it. PTFE is the most lubricated mol that mens ever made... PTFE is mostly known as Teflon for us....
another simple theory, Ester + Base Oil= Ester Base Oil, Ester + PTFE + Base Oil= PolyComplex Ester Teflon Base Oil...hahahaha... u'll get another protection...
