Why does hm oil seem to get a bad rep for being used in a non leaker vehicle?
I did a little calling around (Xom, Sopus, and Valvoline) as well as asking my mechanic about hm oils and they all said it will only attack seals that are worn out because of their thousands of mile usage. New seals or ones that don't leak won't be affected because they are still in good condition.
Most of you here know this, but feel free to continue reading. Why use a hm oil if you don't have a leak? Hm oils offer a more stout add pack for higher mileage vehicles with zinc etc that help combat wear. Plus QS Defy and VML are an exceptional value for being blends.
Here's my personal opinion: Run whatever you want according to a UOA. If you or someone else with your engine has great scientific results, go for it and be worry free. If you do get a leak after hm oil usage, chances are the seal was going out the door anyways.. Or it was already leaking, just very slowly and much less noticeable to where it was considered consumption rather than a lose due to a leak.
The local Mazda and Volvo dealers use VML for their shop as well. New or old car.. It all gets the same unless specified. I'm sure other shops do the same thing.
I'm only posting this because I feel QS Defy and VML (haven't read too much about Xom hm oils) are highly overlooked, while a few here consider it one of their favorite oils. When my stash is depleted, I plan on giving both a try, as well as a UOA in my non leaking/ high oil consuming Jeep 4.0. I blame you all for my obsession btw.
If anyone wants to add to my thoughts, set me straight on an incorrect way of thinking, add another hm oil I left out, feel free to. I'll be curious. Also the VML ATF fluid also interests me, but I don't believe they offer the ATF+4 for my Chrysler transmission. I'd run it if I could.
