Where are the specs for Mobil 1 0w20?

Stainless · Oct 28, 2006

Anyone know where the viscosity specs are for Mobil 1 0w-20, such as the cSt at 40 & 100 C, etc etc? I looked on the Mobil web site, & could not find any.

Also, is there any REAL difference between Mobil 1 5w-20 and Mobil 1 0w-20? There has to be, because they sell both, that question is just hyperbole.

This is the SL/GF-3 version. EOM hasn't (won't?) publish the data for the SM/GF-4 version.

Note EOM does state that the SM/GF-4 version pours at temperatures as low as -53°F (-47°C) and protects at oil temperatures as high as 400°F (205°C).

So the values aren't stated as even being typical values, or as pour and flash points.

Typical wishy washy crapola from large corporations today.

Note that both the 0w30 and 0w-40 pour at -54 C, my guess would be that the 0w-20 does as well, the bottle makes that claim.

What does it say on EOM's website?

Since the pour point currently listed for 5W-20 is -47 C, my guess is that 0w20 and 5w20 are not identical. Also note that the pour points for Xw20 are higher than ther Xw30 counterparts. My guess is that the 20 weights require more or different additives and the additives are affecting the pour points. You can see a similar difference between the standard M1 and the EP versions within a grade. I suppose that someone will blame GroupIII for that difference. I know that I don't know if GroupIII is to blame or not (is consistant though), but my guess is that the difference in pour points is due to the extra additives.

You're guessing the Mobil 1 0w20 pour point went from -57°C to -47°C because EOM decided to add more additives to the SM/GF-4 version???

I find that hard to believe.

It must be one heck of an additive if it also lowered the flash point from 232°C to 205°C

I asked Exxon-Mobil Corporation that question last week and finally received this reponse via email yesterday:

Thank you for your inquiry,

The Mobil 1 0W20 PDS will most likely not be available for another few months. Please check back.

I've extracted typical properties from each PDS and inserted them into a MS Word format table. My intent was to extrapolate 0W-20 from 0w30 information based on 5W-20 v 5w30 comparison data. I came to the conclusion it doesn't work that way.

so i guess the implication here is 0w-20 now, is also watered down with group 3 base

It's impossible to determine that until Exxon-Mobil Corp. publish the 0W-20 specification. Anything else would be pure speculation.

Also, it's been blatantly obvious for awhile, that another poster here has an agenda.

I tried very hard to get the specs for Mobil 1 0w-20, i called Mobil numerous times and the people i spoke to knew nothing, they were totally clueless. 2/4 times that i called i was given the old specs, and the other two times i was told they don't have the specs. How can they not have this information? grrr.

Bryanccfshr · Dec 9, 2006

That is a decent indication of using a lesser base oil in this 0w20 than the previous generation.
It would be easy enough to make a 0w20 with grp III and PPD's .

This is not speculation. This is interpreting patterns with our eyes wide open.

They may not be in a hurry because the performance of the new oil my look bad on paper. They may need more time to explain why the oil may not perform as well for a higher price.

This may explain spotty availability of 0W-20 and my feeling that it's a work-in-progress.

However, 0W-20 do meet same specifications 5W-20 meet.

I checked a few bottles of Mobil 1 at an auto parts store and this is what I found listed on the bottles:
oil weight/pour point on bottle/PDS pour point/flashpont
10w30/-47C/-45C/224C
5w30/-47C/-54C/230C
5w20/-47C/-47C/228C
0w30/-47C/-54C/228C
0w40/-54C/-54C/236C
0w20/-54C/NA/NA

Also note that all the bottles claim the oils protect up to 205 C, not sure what this means, but it doesn't coincide with the flashpoint of the 5 types that have an online PDS.

I mean't to say:
