Why no NOACK #s for Mobil 1 Synthetics?

Valvoline sells around here … what's that about?
Last time I looked … there was no Amsoil on any shelf … and that alone does not work for me …


Up here in the rust belt i see a lot of Amalie oil and Castrol and Valvoline selling lately. 2 Valvoline quick lubes opened up near me. One 1 mike from Ohio line, other 2 miles from me in other direction

Amalie was the first oil I ever dumped in a fill spout

If it really matters to you more than the OEM � be prepared to pay far more than I do for M1 0w20 EP

Formulas are allowed some latitude as well �

Source on AP getting dropped?

 

[4WD]

No source … just does not seem to sell much …

What is the big whoop about NOACK.

It measures the volatility of the finished product. The lower the loss less thicking of the lube in use. Higher quality products have lower NOACK results.

OK I realize that this thread is kinda old but my research on the NOACK is kinda new. Just last week i was educated on the GDI nature of my MY18 Subaru Crosstrek engine (19K miles). I didn't like what I was reading relative to goop buildup on the intake valves of GDI machines. Hence I am intending to take measures in order to address this risk especially since my driving habits place my motor oil in the "severe service" category. Subaru recommends 3k miles or a 3-month OCI. Since volatility is a factor, I am looking at NOACK numbers. Subaru recommends 0W20 but I am considering also 5W20 depending on the spec numbers.

Valvoline has a NOACK of 12 for both the 0W20 and 5W20 weights which, judging from this thread, isn't what it should be. But it would be great to get that number for Mobil 1 since I am leaning toward that product. It's rumored that it might be
Any recommendations from the experts?

BTW it seems that AMSOIL is like Trump. Either it is loved or it is hated. As a result, I have little confidence in the product!

The PQIA looked at M1 0W20 AFE in 2017 and got 10.7% Noack loss...this wasn't the current dexos1 Gen 2/SN+ version of the oil, but XOM has been hinting pretty strongly that they didn't have to make changes for those standards.

M1 5W20 is likely to have lower Noack loss, but there's no guarantee of that unless we see some real test results.

Valvoline Modern Engine 5W20 has a Noack of 12.
Valvoline Advanced Full Synthetic 5W20 has a Noack of 7.6 and a VI 0f 147.

SMH.
Subaru and their low tension piston rings.
I would want a thick 5W20.

I like that Valvoline and Amsoil are pretty good about sharing their Noack results.
VME seems to be starting to disappear and they didn't give Noack for their MST oils, though...

It would be nice to know the secret sauce for VME.
I posit that they are just clearing out inventory.
I am seeing lots of it in all grades near me.

Toyota, Chrysler and GM are also using low tension rings. A lot of research has been done to win the war on friction for fuel economy and wear. However it has added stress to the oil IMO.

Sure.
But Subaru seemed to have some real problems with low tension piston rings.
And they want drivers to use Japanese style 0W20.

Might be a regional thing...a poster here mentioned seeing it on clearance at WM and I stopped by one last night, no VME anywhere.
I was hoping to grab a couple of jugs for cheap, oh well!
It might make a comeback here, who knows?

So did Toyota and GM at first... I think Chrysler was sniffing glue in the corner waiting for the big boys to work it out and then came along after it was figured out to say "me too"

Nothing wrong with that.

My Highlander with Direct Injection and low compression rings spec'ed 0w20 and it didn't use any oil past the first couple thousand kilometers of break-in.
