New M1 EP labels ("Triple Action Formula")

The Dexos label is usually applied to only 0W-20 and 5W-30. Some 5W-20 have it but I have never seen a 10W-30 have the label. It's been posted what the reasons are for this but I forget.
It should be noted that M1 EP High Mileage does not have the Dexos approval on the label

I would run M1 EP 10W-30 in ANY car even the fussy European engines!
It probably can pass bunch of these European standards and then some.
Buy it now while supplies last :alien:

I don't believe that's >3.5 HTHS. I realize that we don't typically see the oil temps seen on the Autobahn but I'm still hesitant to go below the minimum specified operational viscosity.

I agree. should have said or meant the way I drive my cars, I won't be afraid of using M1 EP 10W-30 in ANY car.

My typical RPM is below %50 to %60 of redline (max). Mostly under 3000 & over 2000 rpm. Also hate lugging the engine! Not much short trips or stop & go ... So fussy European engines should fell no stress when I drive them. They should be happy and appreciate a good American oil :)

Kind of boring driving but we have speed limits here and I don't burn rubber or do 40mph in 2nd gear either.

It is, they had claimed A3/B3 until it was removed in the 2021 ACEA Sequence update.

I haven't seen that. I highly suspect that was an error. No one has ever passed GF-5 or GF-6 with an >3.5 HTHS that I know of. The PDS I saw listed A5/B5.

I was thinking of the high mileage, I seen high mileage earlier in the thread and my mind was fixated on the high mileage 10w-30.
 
I'm playing catch up on the latest M1 formulations. Is there anything different with this new Triple Action formulation or is just relabeling? Any recent VOA's show anything different? I see that AFE 0w30 has been updated per latest MSDS. Actually, most of the Mobil 1 formulations show changes per their MSDS over the summer.

I think the only claim we can put a number on is the second "action" which is a claim to exceed
seq IIIH test using a FCA pentastar v6 test engine run under load. Then they look at viscosity increase, oil usage, varnish buildup and also for stuck rings.
I don't know which aspect of the sequence IIIH test was demonstrated as performing "20x better"; the bottle label claims footnoted also mentions "viscosity control", but I didn't see that keyed in the text.

Here is a brief summary of the engine test they are claiming to exceed:
Oil and coolant temps are run very hot, intake air at a moderate dew point and typical underhood temperature ( IAT = 95degF )

Looks like a resurrection of the old "Tri-Synthetic" formula. I'm still holding out for Mobil 2!
Years ago, I coined the phrase Mobil 2 when I gave my 10K used M1 oil to a fellow worker who drove a 25-year-old Chevy to work. He had slow engine cranking in subzero temps along with lifter clatter. I told him to try M1, but the expense was too much for his beater car. Joking, I said do you want some of my 10K Mobil 2 I had not disposed of. He excepted and for another 4 years when he ran low on M2 he would ask if I had any 10K oil for him. Bottom Line: Engine cranking was much faster, and all lifter clatter stopped.
