when there is no vw 508…

[shortyb]

Quote from @achoox "The other way round: Now that the low-sulphur gas can be assumed ubiquitous enough to use 504 not just in fairly short OCIs, will a EA888 gen 3 that I've maintained with M1 502 gain anything (like magically decarbonized intake passages) from switching to 504 ASAP rather than using up the old 502?"

No. Use up the 502 M1. Long debates and speculation abound in many threads here about SAPS and how much (if any) they contribute to deposits. Move to lower SAPS oils was primarily for emission device friendliness. But, less (SAPS) is better for everything involved IMHO.

There is a EA888 gen 3 intake valve video and that engine doesn't carbon up the intake valves like say a 2013 VW GTI does.
Either the Humble Mechanic or Deutsch Auto Parts posted it.

DAP video shows rather noticeable deposits on 2015+ cars, "these cars do not generally have carbon build-up issues".
Humble Mechanic video shows light build overall and thick rings at the edges of valve movement on a 2019, "that's more then I would have expected after 10000 miles" and he goes on to clean it.
It's more than I would have expected given the DAP statement, but it is at least less then the pre-gen 3 cars they show.

It's acceptable to service these engines with different spec oils. With a mind to fuel quality, you really can't go wrong.

 

[Daytona]

You going to guarantee that for the life of the engine?

In this instance I will stick to VAG specs

Daughters car got one too up of 5w30 and was then given an interim Oil and Filter change of 508/509

That's a good position if you don't understand the material presented, why risk it based on someone else's opinion? This is where having confidence in your own ascertains makes all the difference.

It's not like VAG ever made any blunders with their oil service, right? Are we going to follow the 10k "rule" too?

If I were to ask if you could present any engine failures based on slightly thicker oil, like 5w-30 instead of 5w-20 in a Ford. How about in a Toyota... no?

It seems like mfg will universally recommend the thinnest possible grade.....but

I highlighted the last part...

You can't compare VW approvals against Mercedes-Benz, nor dexos and API licenses with those spider graphs. They aren't absolute values that can be compared, only areas of emphasis between one manufacturer approvals. It's useless to do so and Lubrizol tells you that right on the website.

 

[Daytona]

So Lubrizol made a "useless" tool? Ok, that makes sense.

Who said anything about MB specs? Does 229.5 exceed 502 or not? Does it exceed 508 or not? It's not a trick question.

Try reading Lubrizol’s own notes on the page. It explicitly tells you what kschachn said. It’s not useless because it can be used to compare specs within a single brand. The exact tests in each approval are different and performed on different engines in many cases so there’s no easy answer as to if 229.5 is more demanding. It could be in some areas and not in others. They are all based on an ACEA spec initially though.

It’s not useless. But one must use a tool as it’s designed.

And you’re the one who mentioned Mercedes-Benz. It’s in the chart you posted.

“Exceeding” another approval isn’t represented by these spider charts. It’s not a trick answer.

I guess this will forever remain a mystery.

Please stop. You have no idea what you’re doing.

Your reply says more than you think.

Your supposed to check the oil on modern VAG’s with the oil hot, not cold.

Really? Where is that noted? I always check it cold on my GLI.

So you're saying, before a delivery inspection you always warm the engine up. Right?

If I was doing one then yes, it will have the oil level checked after the road test.

If I’m doing a PDI then everyone else must have gone home, I’m normally fixing a EV that’s broken down, plenty of them to keep me busy.
