*Mobil 1 - PAO & Visom

[buster]

On a similar note, Ford just recently created a new spec and Castrol & Ford both found that the Group III formula matched the PAO.

Oils like Amsoil that really want to extend drains may still be better off with the slight advantages of a full PAO based oil. The technology has changed though and the Grp III's are really close to PAO's.

Another food for thought: most of the rather stringent extended drain Euro specs from MB/BMW/VW can also be met with Group III oils.

I was just being a jerk.

I know full well that some will complain about any formulation that moves from primarily PAO to Visom. However, I don't think there are many left that believe M1 used primarily PAO base stocks across the board anyhow. So, this, if you ask me, might represent an improvement across much of the product line.

As for Germany, I think the synthetic labelling ship sank a long time ago. Here, one can use the synthetic term pretty liberally. The term has lost a lot of meaning. There, with all the VW/Audi, Benz, BMW, and other specs, the term has lost relevance. Truth in labelling rules don't do a lot of good if they no longer bother using the term in the first place.

M1 0w-40 and M1 10w-60 are group 3/4 with there being more group 3 than 4

hope this helps



Hey, is still the case M1 5w30 and M1 5w50 full PAO's ?

Riggaz or Tom_NJ ?

I can't speak to the current composition of specific Mobil 1 grades. Clearly ExxonMobil considers it Visom Group III+ base oil to be fully synthetic, and use it liberally in the Mobil 1 line. Given that it is much cheaper than PAO, it makes sense they will use as much Visom in each formulation that its specifications allow, and use PAO and ANs as the adjuster fluids. Visom fits in 5w30s and 5W-50s.

From the Mobil presentation it's quite easy to sum up the advantages and disadvantages of the reformulation.

Advantages:
-Better deposit control (TEOST MHT-4)
-Lower volatility (NOACK)
-Lower avg. cam outlet wear

Disadvantages:
-Higher oxidation (TFO 90/100 vs 94/100)
-Higher avg. conrod bearing wear
-Pour point (48c vs. 54c)
-Higher MRV (29000mPas vs. 22000mPas)
-Lower viscosity index (185 vs. 194)

Correct, for the 0w40.

BUT,the main thing I noticed was how incredibly smooth their new SN oils make my car run. I`m thinking they got this new formulation down impeccably %100.

FYI, the switch to VISOM happend back when the oil was API SM rated.

 

[aquariuscsm]

Well,something is definitely different. It even smells different and it`s slightly darker in color. BUT,the SM oil I`d used last was in the old short fat WM jugs.

 

[aquariuscsm]

SN has a different/better add pack maybe?

How exactly is the SN smell different form the previous SM you have used?
And Is it giving better MPG with the SN formulation of M1?

 

[Art_Vandelay]

"Not only have we replaced most of our PAO with Visom but we've also replaced most of our Scientists with Marketing experts."

And these experts are quick to point out - that a quart of urine with a good additive package will outperform a PAO with a bad additive package each and every time.

How significant are these changes in the real world with short OCI? I know engine type and driving venue re important.

does anybody know what is the current percentage of PAO in the current Mobil 1 0w-40 SN formulation?

i found some answers for my questions,but i need your help.
i want to order from ebay this product http://www.ebay.de/itm/Mobil-1-0W-40-New...=item3cb8dbace4 .
it's Mobil 1 0w-40 new life SHC.
i found 2 msds that interest me.
*.I found the German msds which is dated December 2012.
two questions.
1.is this PAO(Dec-1-ene, homopolymer, hydrogenated Dec-1-ene, oligomers, hydrogenated)
{if yes,then the German version has 50-60%)
and this is ester(POLYOLEFIN POLYAMINE SUCCINIMID)
{if yes it is 1-5%}
?

*i also found the Japan msds which is dated February 2013.
question 1
did the formulation change from december 2012 to February 2013 or is the japanese version different?
(Note: the msds that i found for Japan says Mobil 0w-40 but for the German Mobil 1 0w-40 new life,i dont know if it makes difference)
question 2
for the japanese the value of(1-DECENE, HOMOPOLYMER HYDROGENATED is only 10-20% compared to the German)
and the(POLYOLEFIN POLYAMINE SUCCINIMIDE 1-5%)
it also mentions (Mineral Oil 5-10% which is not mentioned on the German msds)
what's your opinion?

My personal opinion is that it doesn't really matter how much PAO (if at all) it still contains. The various mfg specs that this oil carries speak for themselves. It's the performance that matters, not the individual ingredients.

Yes
