You are seeing more of it. As am I.
New mobil 1 0w40 viscosity

SP or SN(+)?
SP I would assume because that's what's widely available off-the-shelf now.

The hths from esp x4 and fs 0W40 will be the same at 3.8.( API SP Version )
Just a correction, SP FS 0W-40 is ~3.6, not 3.8.

No, both oils have the same.
No. You're 100% wrong. One, the development lead of the ESP X3 oil told me it was lower. Second, it was measured just under 3.6 by HPL's lab in LSJ's video posted last week. Finally, there was an unredacted datasheet that was up for a short time that showed 3.6 cP.
What about the shearing ?
Does it still shear to a thick 30 grade immediately, and then stabilize, like the good old Mobil 1 0W40 ?

If it's your opinion, I'll leave it that way. The Mobil 1 no longer shears like other synthetic oils. Due to the fuel intry, it loses viscosity, but not due to shear.
It's not opinion. I've been told by an XOM engineer and we have objective measurement data to verify that.

It‘s ok.
I leave you in the belief that an xom developer has given you this information. I just said that it's not like that. I think it's all said.

Nevermind, yes.

Yes, it appears so according to tests done in HPL’s lab. Also virgin oxidation is now low indicating no esters in the new triple action formula.
I’ll post the results of Mobil 1 FS 0w40 going into my son’s new 2012 F350 6.2L gas engine.
He bought the truck with 224,000 kms two weeks ago. The OLM read 92%, the oil was clean and on the full mark.
The oil fill cap is 5w20 and that’s what the previous owner used. 2016 and newer have a 5w30 oil fill cap
A week and 1,300 kms later he arrived at my place to steal my 295/65/20 Toyo tires and put them on Ford wheels.
We checked the oil and it was half a quart below the add line.
Shocker. His 2013 5.3L SLT uses one litre of XW40 in 13,000 kms.
Killing time waiting for the tires to get switched over, we ended up at Canadian Tire where the 0W40 was on sale.
By the time I got my 45 year old toddler out of the store, he had picked out $158 worth of stuff that took all my Canadian Tire money.
I topped up the oil with 0w40 and sent him on his way to Vancouver for his paramedic recertification course.
I bought 6 jugs of the Mobil 1 FS 0w40 over a year ago when it first came out in the thicker blend.
That will go into the 6.2 for the next four oil changes.
Lots of highway kms plus a thicker oil should clean up the engine over time and reduce oil consumption.
By which metrics?
If it is better than anything else, in older DI engines in my case.

What engine? I would go Castrol Edge 0W30.
If you have VAG/MB I would prefer the ESP X4 0W-40.
