PAO in Mobil 1 0w-40

[loneryder]

[]
What do you mean by low-ash? Do you mean ACEA C3 (0.8%) or ACEA C4 (0.5%)? Mobil 1 ESP 0W-40 ACEA C3 has just been offered since 0W-40 split into that and the FS version, and that will be it.

The only ACEA C4 they have is a Mobil Super:

Are you saying there is a Mobil 1 esp 0-40 on the market? I haven't heard of it.

Gokhan, I just read your link. When do you think we will see the esp 0-40 in the US?

Again? When is the first time you've corrected me on this? I copied and pasted the thread title from the link to the other section, please take your issue up with the OP of the thread. Of course you are right (as per the content of the presentation linked within the thread) but this isn't a second correction, so while I may have buggered up using copy/paste with the thread title, there is no "again" taking place here.

By "again," I wasn't referring to you but to myself because I had posted the exact same thing under the original thread five minutes earlier.

I don't know. Diesel cars/dexos2/ACEA C3/ACEA C4 are rarities in US. However, M1 ESP 0W-40 comes up if you make a PDS search with the country set to US on their website:

Gotcha, OK, I was like, "WTH??" LOL!

That page has not been updated in some time. The "M esp 5-40" has not been manufactured for over a year.
Wondr if they are waiting for the US to lower sulfur in gasoline in NA?

I have never heard or read a post from anyone with an engine oil related issue where warranty was denied.

It would not make economical sense for an oil company to test and license every product for every OEM on the planet for a nonexistent market share.
For example brand XYZ 0W40 CK-4/SN may pass every OEM and certification under the sun where 0W40 is an approved grade, but not say so on the label.

Some, of course, take advantage of the oil changes. Others will not.

As for certifications, I suppose it might be possible to be CJ-4 and A3/B4 at the same time, but it wouldn't be easy. It's not just a matter of not trying, but setting oneself up for a very difficult job. The E9 sulphated ash maximum is exactly the same as the A3/B4 sulphated ash minimum. And I have no idea how many of the builders' approvals might be mutually exclusive when based upon CJ-4 versus A3/B4.

On a different note, I remember the old Magnatec formula has Ester in it's spec sheet as the component that bonded to the metal surface to resist drain back. The silly "intelligent molecule" name they gave it, or something like that. However I have since heard it no longer uses a ester, but some other chemical, I wonder what that is? It still seems to work very well given the quality of the UOA's coming out for Castrol Magnatec. Looks like castrol is heading in a different direction now days....many paths to the top of the mountain.

Sticking to surfaces is the "lubricity" property of an oil. Yes, synthetic esters and vegetable oils have good lubricity along with Group I conventional base stocks.

A long time ago I had posted the reference below about lubricity. Esters increase lubricity but they may interfere with EP agents such as moly, as they both compete for metal surfaces. They also have stability issues. See page 3:

The following is an excellent article (PDF link) on challenges of using more refined base oils, such as Group II, III, IV, and GTL, as well as esters.

Challenges are great, as Group III, IV, and GTL base oils are regarded as "dry oils" with poor solubility and lubricity. Esters have excellent lubricity but they passivate the metal surfaces and block the AW/EP/FM additives and may therefore increase the wear greatly.

The article doesn't seem to discuss the pressure - viscosity coefficient, which is also important for wear protection but the synthetic base oils have poor pressure - viscosity coefficents as well. Despite this apparent omission, the article is excellent and discusses some great disadvantages and challenges of synthetic base oils and how to possibly overcome these challenges and disadvantages.

Just been by theit production site, and all that was left standing was the classified front. the rest was being torn down. Elektrion is no more.
