I am wondering if anyone can elaborate these new standards in simple term such as min HTHS, long drain, saps content, min. Viscosity, etc.?
My understanding mostly similar to C5 but not sure what is the difference

BMW LL14FE+
VW 508
VOLVO RBSO-2AE
JLR 51.5122
Porsche C20

Thank you

VW 508 / BMW LL is Long Life, provided it is used with low sulfur fuel, because with ACEA C standards, TBN is lower than with ACEA A/B oils.
HTHS is 2.6-2.9.
It is mid-saps oil ~0.8%.
TBN should be more than 6.

Thank you, wondering if there is more info on the other 3 oem standard?
 
As posted elsewhere,

Motul Specific RBSO-2AE (Volvo/Jaguar) 0W20.
--HTHS 2.82.
--mid SAPS.

Motul Specific VW 508.00/509.00 Porsche C20 0W20.
--HTHS 2.5.
--mid SAPS.

It frankly astounds me that there exists a Porsche oil with an HTHS of 2.5,
even if it is for a mere Macan R4.

The claim is that this oil, however thin, holds up
re wear, oxidation, corrosion, shear stability, OCi, everything !

Motul also markets in NA a 0W12 and 0W8 Hybrid oil.
You don't want to see the HTHS on these oils.

Thank you for the summary. I just found Mobil has product that meets most of those even though not certified C5.

Motul Specific RBS0-2AE 0W-20 is for Volvo only - there is a Motul Specific 5122 0W-20 meant for JLR (HTHS 2.7 cP).

And how can Motul Specific 508 00 509 00 0W-20 hold the VW 508 00/509 00 and Porsche C20 specifications when the minimum HTHS for those is 2.6 cP? They appear to have published their non-compliance on their data sheet.

Perhaps the standard HTHS min. 2.5, so the Motul with 2.6 cP meet the requirement, same like Mobil 1 X2 0w-20
 
Minimum HTHS for 508 00/509 00, ACEA A1/B1, Porsche C20 and SAE 0W-20 is 2.6 cP. An oil at 2.5 cP fails to meet all of them. Possibly a typo, but a fairly important one.
 
I've just purchased a 2018 Volvo V40 D3 that takes the RBSO-2AE oil. Seems to be a spec that oils that meet it meet nothing else.

It'll be getting a 5w30 C2 oil once it's out of warranty.

Unless I'm looking at something wrong why does Lubrizol show 508 00/509 00 at a minimum of 3.5? I tried to copy and past with it selected on the chart but wont allow me to do so. Check the first Volkswagen box and check the 508 00 from there. Its listed as 508 88 which I assume is a typo. Its also odd because the chart doesn't gravitate towards fuel economy even though its a 0W-20

508 88/509 99 is an entirely different specification, intended for use in regions with high ethanol or variable quality fuels. As you note, it is 3.5 cP minimum HTHS and is 'high' ash, based on ACEA A3/B4.

Oh thanks that makes sense. I've never heard of that spec before and assumed it was a typo. So they don't have the 508 00 listed yet I suppose. I feel like that spec is more widely know then the 508 88 but I guess not.

Yes, I obviously spoke in error. I stand corrected Sir. RBS0-2AE is a Volvo only spec. There must have been too much information swimming around in my head.

Regarding the 2.5 HTHS, I will hazard a that this oil is very shear stable. Thin, high VI "Japanese style" oils famously shear down to near 2.5 immediately, then stabilize. This "European style" oil does not shear. Nonethesame, you have a valid point. Either it has at least 2.6 HTHS or it doesn't.
