Best HM synthetic oil?? the verdict

[txtruck]

after the many debates on whos works better... which one is gona really work better in a high mileage engine? i heard going back to a full synthetic after an auto rx treatment can reverse the condition of the seals etc... give me (and others) the finale word on the low down GOOD stuff that helps, works and is worth it regardless of synthetic, blend or dino...

So you want the lowdown...well I don't know about that...but opinions are free here...If I wanted a High Mileage Synthetic oil...Well as far as I know there only two choices Maxlife Full-Synthetic and Mobil 1 High Mileage...both have shown decent UOA's here...

maxlife hm has been popular. castrol gtx hm is a sleeper to me. I've read reports of decreased oil useage but the stuff is thick
