The M1 10W30 HM makes sense, given it's outstanding specs-I will likely be using that (or 10W30 HDEO) in whatever 1 ton gas van I find to replace the GMC 6.2 in my sig.
This doesn't tell you as much as you might think.
All it means is that the finished oil may contain one or all of these basestocks.
The SOPUS products are probably mainly GTL, for example although may also be formulated with some proportions of other basestocks.
A better way of reading the tea leaves is to look at low temperature performance and volatility, which are sometimes published by the blender in PDS sheets and are often available from the excellent UOAs published on the PQIA site.

Blend of all 5 groups. Does this mean there's Grp 1 in the formulation?
Irregardless, base oil is one thing, additive pack is another. I prefer a good add pack, after that, base oils.

Pennzoil and Quaker State are having trouble moving away from the Group 1 that caused all the sludging in the 70s.

All I can tell you is that M1 5W-30 HM has stopped oil consumption in my 07 5.3 Tahoe.

Ahha yes, the "secret metal conditioner".
When all else fails, point to it being a "secret" and call it a metal "conditioner".

The SDS info in the links doesn't appear to match the info in the Machinery Lubrication table. What am I missing?

On this Youtube video, https://www.youtube.com/watch?v=fttgg_7NCvA, Royal Purple replied to Cars Simplied's comment saying "Synerlec has a surface conditioning effect that can improve the surface condition of metallic surfaces by smoothing inherent surface roughness. This is not conventional polishing where surface irregularities are simply removed, this is surface asperities yielding the high film strength fluid and the peaks basically are folded over and press into the valleys. The surface takes on a polished surface on a microscopic level, yet no material is removed and no clearances change."
If that's all true, does that sound like what a metal conditioner would do?

They say this:
Conventional. Conventional base oils are generally classified as API Group 2, which means they are highly refined from crude oil. In the past, we only used Group 1 motor oils, and a few conventional formulations as base oils. Now there are even further refined oils known as Group 3.
So grp 3 "synthetics" are in essence just conventionals?

Synerlec was often said to be a sulfurized ester. I remember seeing very large sulfur concentrations of sulfur in VOAs and/or UOAs of Royal Purple oils that contained it, which reinforces the statement that Synerlec is a sulfurized ester.
