I find this an interesting post.
I highly recommend using HM oils at the beginning of a car's life. Their additive and detergent packs are far more robust. Better dispersants as well. If I buying an off the shelf oil, I'd only buy a HM version, in essence the marketing is simple. They put better oil in HM bottles because they know your more likely to need it and are more likely to buy it. See oil has little to do with how it performs. It's about $$$ and whether or not they can get you to spend them. Since they know people won't pay anything more than they have to, they created HM versions and disguise them as oil's for HM engines. Here's the thing, an engine at 75,000 miles, in my opinion, is just being broken in.
