ACEA A1/B1 has different yearly standards (denoted with suffixes like A1/B1-10 for 2010 standard, A1/B1-12 for 2012 Standard). The newer Standards are tougher for an oil to pass.
On Mobil 1's Product Data Sheet it mentions Mobil 1 5W-20 passes ACEA A1/B1.

www.mobiloil.com/USA-English/MotorOil/Files/Mobil_1_Product_Guide.pdf

But, problem is, it doesn't list the yearly suffix (so could even mean its passing a really old ACEA specification which would be much weaker than the 2012 Acea Specification).

Would anyone have proof on the year of the ACEA Specification which Mobil 1 passes?

The ACEA 2012 sequences have introduced many interim measures for biodiesel compatibility. The next issue of the LD sequences is expected to introduce more mature measures in this respect, and perhaps a few more changes for fuel economy and advanced gasoline engine protection. As a result, many will see ACEA 2012 as a compliance exercise only. For consumer use, no reference to the year is permitted (e.g. ACEA A3/B4 not ACEA A3/B4-12). This means ACEA 2012 offers little potential for market differentiation. The European market is driven by OEM specifications and related in-house OEM tests, which provide explicit value to the marketer.
 
Thank you for the links and your reponse. So, When Mobil 1 claims their 5W-20 oil meets A1/B1,
is there some guarantee that they are at least meeting A1/B1-10 (for 2010 ACEA Sequence), or
could Mobil 1 only be satisfying ACEA 2004 specs (which are much weaker and easier for an oil to pass)?
 
Well, the ACEA certifications are "self-certifying", meaning that companies like XOM can approve themselves for the latest ACEA sequence:

Quote:
The sequences define the minimum quality level of a product for self-certification to EELQMS and presentation to ACEA members. Performance parameters other than those covered by the tests shown or more stringent limits may be indicated by individual ACEA member companies.

Where claims are made that Oil performance meets the requirements of the ACEA sequences (e.g. product literature, packaging, labels) they must specify the ACEA Class and Category (see Nomenclature & ACEA Process for definitions).


So while I would probably assume Mobil has approved themselves (and presented the results) for the latest sequence, you would probably have to contact them to find out for sure.
 
Don't focus too much on the A1/B1 part as any synthetic oil will far exceed that standard.

Look for A5/B5.

Which is a very similar standard but a slightly higher.

A1/B1 is the fuel economy spec that was commonly specced for Ford petrol and diesel engines in Europe.

And the oils that met it were mainly semi synth from what i seen, actually never seen a full synth the only meets A1/B1.

Later Ford petrol and diesels all spec A5/B5.

Just what i have noticed since 2008 as until October i have had Ford/Volvo engined diesels thatvuse this spec.

Never used Mobil 1.

But used Mobil Super 3000 X1 FE for many years without any issue.

At half the price of Mobil 1

Mobil 3000 FE was also reformulated a couple of years ago. It was A1/B1 and is now A5/B5. It got lighter in colour but can't say i noticed any other difference.
 
It is mandatory to meet the latest year version of the specs within a year of their introduction.

.... unless they clearly specify what year ACEA they spec to. Famous example is the Quaker State Ultimate Durability QSUD 5w-20 synthetic that only specs to A1-02 right now in time, says it on the bottle, while other SOPUS comparable synthetics spec to the latest A1. Always thought that was strange, so bought Pennzoil Platinum 5w-20 with no such inferior spec.

The ACEA oil sequences are underlying a constant development. Replacement tests and other changes required by the European automobile manufacturers are integrated and new issues are published on a regular basis. As new editions are published older editions have to be withdrawn. Validities of new and old editions are overlapping for limited periods of time as shown in the following table and the accompanying text below. When a new ACEA sequence is introduced, oils with claims against the previous can be marketed only for another two years.


Table: For the 2012 issue of the ACEA Oil Sequences: First claims can be made from 14th December 2012. For another year (until 14th December 2013), oil marketers can still make new claims against ACEA 2010. Starting with 14th December 2013 every new claim has to be made against the 2012 ACEA Oil Sequences. All engine oils using claims against the 2010 ACEA Sequences can be continued to be marketed until 22nd December 2014.

This is not permitted by ACEA. It might not stop someone making a claim like this, but it is against ACEA's protocol.

ACEA A1/B1 sequence is the lowest grade of ACEA sequences and all API SN/RC synthetic oils should easily meet it. There is nothing to worry about it. The ACEA A5/B5 category is the premium category and harder to meet. That said, Mobil 1 also meets ACEA A5/B5.
 
Response from Mobil

M1 5W-20 has the 2010 ACEA specs.

The definitions of each of the specs is very dry. Here's a good table that shows the highlights -- if you're interested.

Regards

They also sent a link to 2010 ACEA specs...

Since 2012 specs elevated some of the 2010 A1/B1 specs to the A5/B5 level but Mobil 1 already satisfies A5/B5 anyway, there is nothing to worry about.

"A1/B1 has been upgraded (in 2012 from 2010): Evaporative loss (NOACK) less than or equal to 13%; VW TDI and OM646 Wear now matching A5/B5 performance but no piston cleanliness and sludge requirements (as in A5/B5)."

I wouldn't assume that across the board as there are some large differences. SN/GF-5 is not suitable for diesels whereas A1/B1 is, and for long drain intervals too. A1/B1 allows for much higher sulphated ash. If you can meet all that with an SN/GF-5, hats off to you.

If you look at the Lubrizol spider you will see that they are quite different, the minimum requirements anyway.

We have been referring to Mobil 1 5w20 which does not meet A5/B5. HTHS is too low to qualify

No, they are different. CJ-4 is for diesels and have very different requirements to SN/GF5.
