M1 EP 0W-20 Shortage?

That to my knowledge is the only Castrol retail product that carries MB229.71 approval, whereas the only Mobil oil that has MB-Approval 229.71 is ESP 0W20, Mobil 1 EP is only .8% ash to my knowledge with the mostly PAO composition and that it's been engineered for drain intervals up to 20,000mi, I wonder what really keeps it from being MB229.71 other than Mobil wanting you to fork out more cash for a Euro specific oil.
I am assuming Mobil 1 EP and Mobil 1 ESP has different formulation?

The Castrol EP is also 20k miles OCI.

Probably nothing, but ESP 0w20 is also approved for DexosD and VW 508/509. The market share for 229.71 is quite small and it probably does not make much financial sense to have two approved products.


Just a suggestion and my opinion of course. Castrol Edge 0W20 Extended Performance has the MB229.71 approval while Mobil 1 EP does not. Going with an oil with approvals that goes through stringent testings is much meaningful vs what is on the SDS sheets is what I have learnt on this forum.

It is a fair point, but I am doubtful that M1 is unable to meet those requirements.

You can't use the Lubrizol tool to contrast specs outside of their org BTW (you'll see they note that). So you can't compare MB229.71 to GF-6 for example, only other MB specs. It's a relative performance tool designed to show the emphasis on parameters within a given subset of OE or industry specs.

Yes.

Looking at the Afton Spec guide, MB229.71 requires:
ACEA C5

Which is why Mobil has an ESP oil for it, not a traditional PCMO.

The rest of it doesn't look overly stringent (but stringent enough, it is an MB spec after all):
Noack limit: 11%
TBN: 7.5
SA: KV100: >/=7.8cP
HTHS: 2.6-2.9
Zinc limit: 0.04%
Sulfur: 0.3%
Phosphorous: 0.07-0.09%
Calcium: 0.3%
Magnesium: 0.3%
MRV: 30,000

Plus quite a few engine tests.

But the C5 requirement is why you won't see EP 0w-20 meeting it.
 
The 0w20 uses majority PAO. Other EP grades are PAO/GTL/III+.

buster: Is this still true with GF6A? Or are we still putting to much faith in an ancient SDS ?

Perusing my files, I see the initial release 0W16 is a majority PAO on the SDS. I cant find my 0W20EP file.

And it's funny you guys jump on me all the time for my "real" vs. "faux" synthetic argument, all they while hording
the REAL stuff !

You've been caught with your pants down - and- your hand in the cookie jar ! :) :) :)

I know enough to be dangerous but here is the most recent MSDS.

Walmart.com has it back in stock as of this morning.

hiding stuff on SDS is an art. shell’s method of listing every base oil cas number to ever exist is probably the best way of confusing oil nerds
As someone who once wrote these sheets for a living the cardinal rule is to never, ever reveal any sort of trade secret whatsoever. Ever. Yes you want to provide firefighters and first responders with useful information for everyone's protection but that's actually not too difficult under the rules.

In fact if it is possible to deceive a competitor while providing the necessary safety information, then all the better. Double win.

C5 is Mid SAPS from what I understand. Is this correct? If so, Mobil 1 EP 0W20 is also a Mid SAPS oil, no?

ACEA C5 Stable, stay-in-grade Engine Oil with Mid SAPS-Level, for further improved Fuel Economy, intended for use as catalyst compatible Oil at extended Drain Intervals in Vehicles with all Types of modern Aftertreatment Systems and High Performance Passenger Car & Light Duty Van Gasoline & DI Diesel Engines that are designed to be capable and OEM-approved for use of Low Viscosity Oils with a minimum HTHS Viscosity of 2.6 mPa*s.

It's nothing (I mean technically it's closer to low SAPS) because it has no ACEA approvals at all, the product isn't targeted at any of the ACEA stuff, it's a North American PCMO, whilst C5 is the base for the aforementioned Mercedes spec.

Mobil produced a specific Euro lube that was C5, so it's logical that they would approve that lube to MB 229.71.

The ESP 0w-20 actually has higher Zn/Phos levels (800/950) than the EP 0w-20 (650/750).

The ESP oil however, is more GTL and less PAO (20-30%), if that's important to you.
 
Are they selling through to move D1G3 product onto the shelf?

"First available use for the Dexos1 Gen 3 mark will be Sept. 1, 2021. In keeping with how the OEM handled the transition to Dexos1 Gen 2, marketers will have 1 year to sell off their Gen 2 products before they must be pulled from the shelves, he said." - GM Engineering Manager Nathan Siebert

Most likely what happened was a resurgence of the deal and rebate hitting Slickdeals again recently.
 
I cannot find a 5qt jug of M-1 0w16 online at Walmart or in any local WM stores. l really hope that it becomes available soon.
