Trying to find the new Top Tec 4200 5W-30 New Generation 8973. Even when you locate it (5L) on several sites like AZ or ECS, it's the wrong old SKU 2011 which is NOT the "New Generation".
 
Sometimes, L-M uses different part numbers for different markets. For example, the US part number could be different than the part number in Europe.

Also, the new generation 5w30 in the 5L size shows up as Part #2011 on Liqui-Moly's US site.

Sometimes they do update the product itself without changing part numbers :sneaky:
 
Didn't see that, thanks. Is it the same formulation? The outside of the jug is different too. Just trying to find the "best of" for my '18 C7 A6 3.0 Audi and my '17 Q5 with the same engine. They list "major engine" problems as one of the Q5 problem areas. I'm using up my stash of GC, the QS Euro from the WM sale, the OE Castrol that nobody liked and the Valvoline advanced that was from a Lowes clearance. Now I need to get rid of my giant cage from an old Blockbuster store and focus on trying to find the best, at the best price and stocking up on that. Any recommendations would be great, thanks.
 
Are the base stocks of the M1 true synthetic? I know (maybe) that in Europe the base stocks have to be true syn, unlike in the US they don't and can still be called 100 syn. Not sure of that though... The LM site states that "the oil change intervals of up to 30,000 or 50,000 km or every 2 years for low mileage drivers are thus possible". Not that I would let it go that far.....

Only Germany has a marketing rule (or whatever it is) regarding the definition of synthetic, not all of Europe.

Group III hydrocracked synthetics are synthesized all day long. It's not just a purification of the feed stocks. Intermediates are assembled to synthesize the final product.

And for what it's worth, Group III hydrocracked bases were marketed in Europe as synthetics way before they were here in the US. And they still are.
 
There's no ESP recommended on the M1 site. Just these....if you really need the 505 spec. I see some of the top oils have the MB.52 spec and the VW 504/507 but not the 505. Not sure what the differences are.

Mobil 1™ FS 5W-40​

Mobil Super™ Synthetic Euro 5W-40​

 
ExxonMobil never makes a recommendation outside of the approvals the oil holds. The most you will ever see them do is make a statement such as “ in the opinion of ExxonMobil” for expired approvals or ones that are no longer current.

In these cases, you have to read some tea leaves in regards to the HT/HS and SAPS level, or other similar approvals the oil may hold.
 
Here is from LM site for the oil you have in mind:

and from me:

VW 505 is no longer a current spec if I get it correctly, there should be no oil made specifically to meet VW 505 as main cert.
Older VW 505 was a Full-SAPS oil, then later with VW 505.01 they made it Mid-SAPS oil which was replaced by VW 504/507 Mid-SAPS oil.
 
Obviously, or not, there's something in or not in the specs that the manufacturer wants or wanted in this case. Maybe not as it's main cert. but still included in it's list, and not just a recommendation. I'll look if any of the other latest and greatest oils include 505. Maybe not.... What was the 505 requirement that made it different anyway?
 
Please read again, that LM oil is not VW 505 certified but recommended for engines calling for it.
High SAPS oils are ones that allow long OCIs on cars with emissions systems that can handle high SAPS.
Looking for VW 505 oil is like looking for API SL oil just because your 2010 owner's manual called for it back then.

I got that, but it makes you wonder about what is missing from the formulation. Is it just too expensive to get the approval, especially for an older spec., or is it NOT for 505 specked vehicles? So, after all the years of checking if the oils that you want to buy have the proper spec, you basically just guess that these "high end" oils are ok if they are recommended?
 
One thing missing from 505 00 vs. 507 00 is a long-drain capability as well as having a higher Noack. 507 00 is superior in every way to the old 505 00. Since the approval is being phased out (or has been already), I doubt VW would actually issue an approval for a 505 00 oil.

If I recall correctly the wear test for 507 00 is twice as demanding as for 505 00 (or something like that). Whatever the case, a 504 00/507 00 oil is one of the best VW approvals there is.

Imho, get a VW 504/507 oil, ideally while also MB 229.52, the oil will be C3 then anyway.
In short, 507 oil won't allow as long of the OCI vs 505 oil but will allow for cleaner engine and cleaner exhaust (think of cat converter).
