As of today, according to the product data sheets, M1 High Mileage 5w30 and 10w30 meet API SL while 10W-40 High Mileage meets API SN. A difference of two API specs there is strange. Anyone know why this is?
M1 HM oil specs oddity

It meets the requirement for SN. I'm guessing they finally got around to having it approved.
Maybe they are bringing them all up to date and they have only updated the 10w-40 spec. sheet. I'd have to look at the release date on the others. if they where released today that theory goes out the window. I almost hope that isn't the case as I really liked M1HM's stout add pack for my older rides. Excellent sleeper oil...
No, it is not a reformulation.
It's like what Buster mentioned, the HM oils surpass the SN limitation, but they are set higher for the 40 grade, so it meets SN requirement, while the other don't.
That i know of as of August (at least), Mobile 1 10w40 HM, has been/meets SN requirements.

That makes sense.
They are using the same additive chemistry (low ca/and mg) in all their Mobil 1 oils, including the HM. The only difference, from what I could tell seeing the VOA's posted here, is that the HM oils have higher ZDP levels. I think around 1,000 ppm. So those are good choices for older engines.
The regular Mobil Super oils use the more generic additive package.

the sl still has all the good stuff

Good call. That could be it and I hope it is so they keep the ZDDP high like it has always been. This shows API SN phosphorus limits by viscosity grade. http://www.gf-5.com/uploads/File/API SN Discussion.pdf

This has been answered here numerous times in the past. API SM/SN has stricter limits on add pack in the Xw-30 grades. These limits are more relaxed for Xw-40 grades. That's why M1 HM 10w-40 can be API SN but M1 HM 5w30 and 10w30 cannot.

I hope that ends all the confusion. The HM 10w40 "SN" still "has all the good stuff". Phosphorous and zinc levels vary somewhat, with the AFE, HM, TDT and Euro. Magnesium is found more in the HM blend then the others.

Just a comment, but if the reason to go with the HM 10w30 and 10W-40 is the higher ZDP levels why not just go with M1 0W-40 that has the same ZDP level plus a much higher 185 VI meaning a lower start-up viscosity at all temp's to even the 10w30.

My reason would be for the seal conditioners since my VW is a 2003 with 150k miles.

The simple answer is M1 0w-40 is not high mileage oil. Different brew without the adds for cars that have high mileage problems. The thinnest is 5w30.

Low mileage. At 300K or 400K miles it might be "high mileage"

Seal conditioners would be the only reason to go with a high mileage oil and of course only if you have an existing seal leakage problem.
And I would avoid the 10w30 like the plague like all 10w30 syn's.
If you need an oil with a HTHSV higher than 3.3cP simply blend the 5w30 and 10W-40 to get the desired HTHSV.

My gas mileage with M1 10w30 HM in my VW was really good. Usually I used XW-40 oils meeting VW 502. It's also used GC 0w30 and while there are too many factors to attribute it solely to the oil, the gas mileage was on the low end of what I've seen with that oil. It doesn't get very cold here and with my VW I tthankfully found that I don't need to be that concerned with using only high VI index oils.

I emailed Mobil and they said the add pack is still the same. They said it`s also an excellent flat tappet oil. It`s the smoothest running oil I`ve ever used! I LOVE the stuff!!!!!!!!!

I'm finding the same in my Ranger. Not usually a Mobil fan but this HM is good stuff.
