The test was already under development in 2016, the date of the Lubrizol brochure that was pulled from. Given the amount of "heads up" the industry has, Mobil was, as they typically are, well ahead of the curve on that one.The API SP M1 ESP versions—aka mixed calcium–magnesium detergent versions—would definitely be subjected to the MB LSPI test.
However, I doubt the previous versions were ever subjected to the MB LSPI test, as the test was introduced circa 2020, and blenders get a grace period when OEM specs are updated. The older versions were very high in calcium and were formulated with no LSPI protection in mind, and I doubt they would have passed any strict LSPI test. Note that these are low-ZDDP oils as well; so, you don't get any help from ZDDP in mitigating LSPI.
That sounds like revisionist history, with all due respect. Mercedes 2009 from the Afton handbook, note the timing chain wear test:One thing that everyone must understand is that LSPI protection and timing-chain-wear protection were championed by API and ILSAC, and ACEA and European OEMs followed suit several years later.
How? If Mercedes had it under development in 20-freakin-16, and SN Plus didn't come out until the end of 2017, how is it a response to SP if it existed before SP did?Therefore, MB 229.52 LSPI test did not come to existence in thin air, but it was created in response to API SP and US OEM LSPI tests.
I disagree vehemently. I'm not sure why you feel so necessarily invested in championing the API on this subject, but ACEA has typically been the one taking the lead because it is made up the auto manufacturers, who have a vested interest in protecting their product, unlike the API, which is comprised of the oil companies, who have a vested interest in making the most money selling the cheapest oil possible that passes the performance requirements. That's why XOM pimps their EHC Group II+ products for Dexos for example.In fact, the new ACEA A7/B7 and C6 categories use the same API ASTM D8291 and D8279 tests for LSPI and timing chain, respectively. Interestingly, the LSPI and timing-chain criteria for both API/ILSAC and ACEA specs are identical, showing that the API/ILSAC and ACEA additive packages have been converging to being identical now. US/Japanese oil specs have been ahead of European oil specs in these two respects; so, Europeans are playing catch-up now.
Yes, as an extension of the API and most of the tests are just the API test or extensions of them.It is the same with ILSAC. It is also lead by automotive OEMs.
That's not how the API/ILSAC specs are developed. It is a consortium of automotive OEMs and additive companies.Yes, as an extension of the API and most of the tests are just the API test or extensions of them.
This is simply wrong. API SN PLUS and SP came before ACEA A7/B7 and C6. ILSAC oils switched to a mixed calcium–magnesium detergent long before ACEA oils did, which are still playing catch-up in LSPI protection.The test was already under development in 2016, the date of the Lubrizol brochure that was pulled from. Given the amount of "heads up" the industry has, Mobil was, as they typically are, well ahead of the curve on that one.
But regardless, this thread is about current versions of the product and I think we've established that regardless of what some "contractor" answering e-mails for Mobil says, this oil is setup to mitigate LSPI, and it's likely been that case for several years now, at least.
That sounds like revisionist history, with all due respect. Mercedes 2009 from the Afton handbook, note the timing chain wear test:

LSPI testing was introduced by the API under SN Plus, in November of 2017. Yet Mercedes clearly already had an LSPI test under development in 2016. Noted under the 2017.1 revision, the test release was expected to be 01/03/2018:

There was also an LSPI test as part of PSA service ACEA C5 (2017):

So I'm not willing to entertain the idea that the Euro marques all had their heads up their posterior and had no knowledge of LSPI and didn't develop any test protocols until the API did it.
How? If Mercedes had it under development in 20-freakin-16, and SN Plus didn't come out until the end of 2017, how is it a response to SP if it existed before SP did?

That's why XOM pimps their EHC Group II+ products for Dexos for example.
The Euro marques were the first to really push extended drains and stay-in-grade requirements. They developed extremely rigorous performance testing under very demanding conditions (like A40 for example) and the domestic marques are very much only recently catching up on that, with probably the biggest contributor being GM with dexos and its performance requirements. Ford's are all just extensions of existing API tests, same with FCA.
Edit to add: And this is all very good for the end user, who gets a better oil as a result. But, to ignore the leadership role ACEA and the Euro marques have historically played is to do a disservice to its significance IMHO. As I noted above, things really started to change on this side of the pond around when GM introduced dexos.
I know the details of the tests, these are publicly available, but ultimately, the API is out for its best interest and the OEM's weighing in haven't done so with the same level of rigour as their European counterparts.That's not how the API/ILSAC specs are developed. It is a consortium of automotive OEMs and additive companies.
ACEA doesn’t have to do anything for manufacturers to make their own approvals more stringent.This is simply wrong. API SN PLUS and SP came before ACEA A7/B7 and C6. ILSAC oils switched to a mixed calcium–magnesium detergent long before ACEA oils did, which are still playing catch-up in LSPI protection.
That Peugeot spec seems to be regarding oil aging but not LSPI, and I don't know how the word LSPI got in there.
Sweet Christ on a friggin' cracker Gokhan, there's more to LSPI than just calcium. You know full-well that ZDDP mitigates LSPI and the Euro oils have historically had higher levels of ZDDP.This is simply wrong. API SN PLUS and SP came before ACEA A7/B7 and C6. ILSAC oils switched to a mixed calcium–magnesium detergent long before ACEA oils did, which are still playing catch-up in LSPI protection.
It's LSPI, even Fuchs notes that, like GM, PSA came up with their own LSPI test before the API implemented anything:That Peugeot spec seems to be regarding oil aging but not LSPI, and I don't know how the word LSPI got in there.
Wait for it, the usual forthcoming response after all of this is “of course I didn’t mean that…”Sweet Christ on a friggin' cracker Gokhan, there's more to LSPI than just calcium. You know full-well that ZDDP mitigates LSPI and the Euro oils have historically had higher levels of ZDDP.
It bothers me to no end when you say "this is simply wrong" and provide absolutely NOTHING substantiative to refute it, disagreeing with it only because it runs contrary to the narrative you've previously spun. You cannot deny that Mercedes was CLEARLY aware of LSPI and working on the limits for their testing protocol as of 2016.
Here's a wild idea: Perhaps the higher ZDDP levels in some of these oils provided enough LSPI mitigation that they didn't need to reduce calcium?
It's LSPI, even Fuchs notes that, like GM, PSA came up with their own LSPI test before the API implemented anything:

Thesis? Good grief. It's a bloody (ridiculous) BITOG discussion Harry Potter, I award your house no points! Why does it have to be SP rated? Why can't it just be one that has the PSA and/or Mercedes approval post 2018?If what you're saying is true, you can easily prove it: Simply find a counter example to my claim: an all-calcium API-SP-rated oil. If you cannot find it, my thesis claiming that there is no such oil stands valid.
Dude, I literally just said, in the text you quoted, that LIKE GM, PSA introduced their own test before the API had one.By the way, GM introduced dexos1 Gen 2 in 2015, which predated every Euro OEM's LSPI test. As I said, API/ILSAC spearheaded LSPI formulations. You can't find any non-LSPI API/ILSAC oil any more, but the majority of Euro oils are still non-LSPI.
You have been trying to prove 2 + 2 = 3, but it hasn't been going anywhere. You are simply wrong on this. That grossly extrapolated plot that goes to a ridiculous 2,000-ppm phosphorus doesn't help with anything. You should also know that the acceptable number of LSPI events is more like zero, not 10 or 20 (regardless of the actual limit in the tests). Moreover, the only mainstream PCMOs with high ZDDP are ACEA A3/B4 oils, and they only go up to ~ 1,000-ppm phosphorus, which is not much higher than ILSAC oils. As you know, Castrol and Mobil 1 have both updated their A3/B4 oils to a mixed calcium–magnesium detergent now. Nobody will try to make an LSPI oil with an all-calcium detergent, as calcium is the main LSPI culprit in high-BMEP TGDI engines.We know that calcium is an instigator, while ZDDP is a mitigator:

Let's veer ourselves back to the discussion at hand here for a moment. We are talking about DIFFERENT LSPI tests, not just API SP (or SN Plus for that matter). LSPI is LSPI, if it is being tested for, it's valid. That's the crux of the original argument in the context of mitigating LSPI when it was being stated, absolutely, that this all just appeared out of the ether with API SP and the counter was that no, that's bovine excrement, there have been OEM tests for it long before API SP.
Dude, I literally just said, in the text you quoted, that LIKE GM, PSA introduced their own test before the API had one.
I'm done, this conversation is making me angry and I hate that I'm wasting my time on it here playing whack-a-mole with your gotchas and tangents which ultimately serve me no purpose and just drive up my blood pressure.

Re: "Afe was always and still is “whatever “ oil. Here is evidence to the contrary: Ford, at least for its extremely popular Ecoboost 3.5 engine, requires its customers to use a 0W30 oil meeting its WSS-M2C963-A1 standard when the temperature is expected to drop below -20F. M1 AFE 0W30 is the only oil for sale in the US that claims to meet that standard, and it took Mobil four years to get certification after Ford published the requirement. So it appears to be a very hard standard to meet, and only M1 AFE meets it.API SP has LSPI test.
MB229.52 has LSPI test.
That is it.
Going back to original question, ESP is much better oil for slew of other reasons. Afe was always and still is “whatever “ oil. Shears down too fast etc. If going that type of oil M1 5W30EP would always be my choice over Afe.
That is where I am going to end my involvement.
On another note, maybe some of these Asian manufacturers should give consideration to design engines bit better.
Unless they modified the M1 ESP formulation, it would hardly pass any LSPI test with 1,700 ppm calcium if at all.API SP has LSPI test.
MB229.52 has LSPI test.
