Mobil 1 HM is SP but it sill isn't GF-6A. Does anyone know if it's still >3.5 HTHS?
100C = 12 cSt
40C = 80 cSt
100C = 12 cSt
40C = 80 cSt

I must have missed it, when was it HTHS >3.5cP?
I thought it was like 3.3 or something? It's been a while, lol.
For years when it was A3/B3I must have missed it, when was it HTHS >3.5cP?

Current PDS lists nothing ACEA from what I can see:Historically, it's been 3.5 for a long time. Part of the ACEA A3/B3 rating so it can't (couldn't) be less.
If it's still A3/B3, its still 3.5 - one proxy to tell since they've dropped revealing that. It's still not EC, so safe bet it still is.
I think it's interesting they stopped claiming A3/B3 on the 10W-40, here's a Jug of 10W40 SP, that I have out in my garage from June of Last year.

But the current image on Walmart shows no ACEA A3/B3

I'd think just about any decent 10W-40 could claim A3/B3, so I wonder why they stopped claiming it
I have found pictures of M1 HM 10W-30 with API SP with and without the ACEA A3/B3. I have been told you now have to meet A3/B4 so may be the reason for the removal. Not sure if the oil can meet B4.
It appears A3/B3 was removed in ACEA-2021ACEA specification for PCMO | Chevron Oronite (Global)

I only the HM version.For years when it was A3/B3
I only the HM version.
Just looked through my archives. M1 10w-30 - HTHS 3.0. M1 HM 10w-30 - HTHS 3.5.
Right. The data I was referring is about 10 years old.I think it likely still is just based on the 100C and 40C numbers and the fact it still isn't ILSAC but with HTHS no longer on the PI sheets, A3/B3 abolished and A3/B4 requiring a higher TBN I don't see any way of confirming without Mobil says so or paying to have it tested.
