You sure they don’t change clearances for each engine?
Not all 2.0 admits the three oil specs options….. maybe some diffrerences beetwen the engines?
Enlighten us how those engines work in environment where oil temperature might not get to operating level? Fairbanks, Alaska? What is their lifespan running oil that is xx times thicker than 40 grade? How does that works with “clearances,” or “piston rings?”Not all 2.0 admits the three oil specs options….. maybe some diffrerences beetwen the engines?

who says engine explode using a high viscosity oil??? Not me…..Enlighten us how those engines work in environment where oil temperature might not get to operating level? Fairbanks, Alaska?

By the way, VW approvals are based on HTHS not “5W30.” Do piston rings distinguish between 5W30 ILSAC GF-6 and VW504.00/507.00. What if you run Pennzoil Platinum 5W30 with KV100 of 9.2, and let’s say Mobil1 ESP 5W30 with KV100 of 12.2. Does engine explode if one runs 5W40 with KV100 of 12.8 or you need 5W40 of 14cst and up?
The oil reaches 150c, not in sump in regular use, but in certain spots, for sure! HTHS is determinant. I worked on development of oils that were specifically aimed at VW approvals. It is not just temperature, but testing methodology behind HTHS.What I Learned Today — Bearing Clearances vs. Oil Viscosities
Choosing your oil viscosity based on bearing clearances can be challenging. Luckily Jeff Smith adds some insight into the problem.www.enginelabs.com
who says engine explode using a high viscosity oil??? Not me…..
maybe my english its not good enough?!
The viscosity is primary selected by design of internals engine, working temp and oil pressure….. if the oil never achieves the propper working temp, you can uses a less viscosity oil or short the OCI….
VW aprobals are not based “only” in HTHS, the oils rarely achieves the 150* of HTHS test, not even close in a standar use!
The piston rings designed to work with w20 oils has no problem to deal a w30 (maybe some w40)….
But cant deal correctly with a w60 for sure, that you mentioned early (the engine do not explode or any other ridiculous assumption), but for sure works in a higher internal temp, higher wear (especially in cold starts) and loose some power!!
(Studies confirm that 20cv aprox was missing beetwen w30 and w60 oils in some engines)
in a lot of Europe webs claims that 508-509 specs must includes zirconium in his oil additives (I cannot confirm this statement, nor deny it)
hope my english was ok (its not my language)
?? They have their own service manuals. Part numbers are different. No specific technical recommendations?? What??None of those models have specific technical recommendations in erWin.
But it's not. Check the engine codes, compare part numbers of different components, they aren't the exact same engines.Another reference you can have is that the same EA888 engine is used in different models besides the Tiguan and yes, those also can have different oil recommendations.
I never made any of those claims. What I said was it's not unreasonable to believe different engines may have different lubrication requirements.Whatever you wish to claim as yet another reason why a specific engine needs a specific grade still has no technical backing. Zero. Please tell me what is unique about the Budack cycle that requires a 20-grade oil. There isn't one.
Requirements is an open-ended word. Some engines may require an oil with a higher HT/HS to prevent excessive wear, but this in no way excludes the use of an oil with a higher HT/HS. Too low of a film thickness will damage an engine, but the other way around is not true.?? They have their own service manuals. Part numbers are different. No specific technical recommendations?? What??

Regardless of spec, in the tuning world it's best to run with what your tuner recommends based on subjective experience and platformRequirements is an open-ended word. Some engines may require an oil with a higher HT/HS to prevent excessive wear, but this in no way excludes the use of an oil with a higher HT/HS. Too low of a film thickness will damage an engine, but the other way around is not true.
And yes some may require higher oxidation resistance and other properties. But as long as you have an oil that meets those needs then again you can use a different grade as long as it is not too low.
In the case being discussed here no engine requires 508 00 oil. None.
It happened to friends of ours with a 2011 Pilot. Recall these were the VCM motors where the rings on the deactivated cylinders could coke up. Several dealerships denied coverage of the ring replacement under the extended warranty campaign because the service invoices showed repeated use of a viscosity other than the 5w20. I know because I assisted them and eventually one dealership got Honda to cover about half the cost.Of course there are also the dire warnings about warranty denial, but again no one has ever posted that this has happened to them personally.
Yes you do need to compensate for low-viscosity oils.If anyone is doubting @930.engineering for some reason, here is the 508 info straight from vw/audi:

This is from their study guide for dealer techs, not marketing material. There are no changes in bearing clearances, they are already quite tight in the high performance versions.
For sure, but it's not a change that prevents people from using the old x30/x40 502 oils.Yes you do need to compensate for low-viscosity oils.
