Yup - I know that. We don't have user data that proves POE is a key factor in stopping ticking, I think - based on what I recall from the tick tester crew. But my short term memory is bad.
@Burla - if you have time to comment, please do so.
I'm pretty sure the additive package is critical to stop ticking.......heavy dose of antiwear additive that plates out on metal surfaces, specifically the lifter roller and needle bearings, and cam lobes.
I'm not sure if the type of antiwear additive matters, MoDTC (Moly) or ZDDP (Zinc phosphate), or both. We know for sure a heavy dose of both (Red Line) work. But would heavy Moly OR Zinc only work? Not sure. There is evidence heavy Moly only works when people have had success adding LubeGard (Moly only) to various base oils, but don't recall if this blend stopped ticks, or if only ticks didn't develop.
I am unsure if the surface clinging effect of the polar POE base oil matters much - i.e., whether an API Group V base oil is critical in tick extinguishing, or if Group IV (PAO) and III (Cat Cracked Hydrotreated Crude or GTL) work just as well as just a high quality additive carrier.
