What makes a HM oil different from non HM oils ?
The voa on QS 5W-30 Synthetic vs QS 5W-30 HM is not a lot different other than the HM has a much larger amount of Boron compared to QSUD. So what’s the additive that makes it HM ?

HM oils usually have more seal conditioners for the old seals. Not much else of significance.
Another thread noted that HM oils might not be sold as much in the future as oils are now said to be "All-Mileage" for old and new engines. (Shell Rotella Gas Truck and Castrol Edge)

Totally understand what your saying
But in the additives listed for both oils, the HM oil has nothing different than the Synthetic

Those oils have different base oils, conventional vs. synthetic, which by itself will trigger formulators to use different amounts and types of chemical additives, some of which do not show up on elemental ppm readings. Can't tell everything from this kind of VOA. Some clues are there. Not many though.
The need for HM oils isn't great due to use of so many silicone rubber seals that don't respond to much anyway.

There have been threads on this before.. from what i remember its the amount of detergents.. (thought process being that an older high mileage engine will have more deposits and varnishes).

And seal conditioners.. all oils have them.. I dont think anyone has ever said what the seal conditioner actually was..or if it even shows up on an oil analysis.

There have been claims that HM has alot more seal conditioners..but i dont think there is any way to prove it.

Actually VWB and Maxlife as well as both flavors of ST syn are the same price off the shelf. They all get you big time for oil changes though. Think branding of oil is in a big shake up right now. Always afraid that my oil change place will declare VWB a semi syn and decline my stash of ten buck oil coupons.

Think that Maxlife has slightly more robust additive levels while HM ST is identical except for slightly more seal conditioners.

The seal conditioners are not going to show up on a VOA like the one pictured from PQIA.

To see those compounds it would take a much, much more expensive analysis test to be performed.

Use your Google machine and search for "what's in a high mileage oil"... there's a wealth of information out there.

Spoiler Alert: it's more than just added amounts of FM's and SCA's.

???

That's not accurate. They may contain higher amounts of FM's or higher lvls of dispersants to combat blow by or have higher (double digits) TBN or a different detergent pkg to combat sludge... plus, when did lubes STOP being ok for use on any mileage of vehicle?
