So within that requirement, we would just like to know what the best oil is? Does anyone know much about the add packs of Ineo or LiquiMoly?



Agreed. My post was what makes 508 spec different from our top tier API oil?
Kendall is blowing it on their oil finder app.

At this cost the dealer service looks cheap

It wouldn't necessary build up oil pressure faster, instead it takes a longer time ....
This has no relation to suitability of oil viscosity grades for this gear pump design.

How would oil thicker than 0W20 damage this gear pump?

Man, what happens when it's -20C, instant engine failure when the oil is orders of magnitude heavier?

It's not beyond VW to have such a failure with something new.

Inadequate engineering ... pump gears must be made out of pot metal. They disintegrate before the pump's pressure relief valve kicks in.

Ok, got it ..... as increased oil temperature from viscous drag melted away the gear pump material and one should consider blending 0W20 in 1:1 ratio with kerosene for increased oil pump life....

i was just staying aboaut the new gear pump design itself, then i was stating what vw says about 0w20 and not using it can cause damage
all i can tell you is this all is directly from the vw self study guides on the new engines for employees, i didnt write it. so this all comes from VWs mouth

FUCHS

Mannheim, February 2017
Introduction of the new TITAN GT1 LONGLIFE IV SAE 0W-20 engine oil for the new
VW specifications VW 508 00 / 509 00
General information
Specifications 508 00 and 509 00 concern the so-called �VW Blue Oil� for the latest
generations of engines from VW. The specifications demand an oil in viscosity class SAE
0W-20 with a reduced HTHS viscosity of at least 2.6 mPa.s. This allows fuel savings of
at least 4% to be achieved. The first of these engines have been available on the market
since the end of 2015. Specifications VW 508 00 and 509 00 are not backwards
compatible with previous VW specifications. In contrast, specification VW 504 00 can be
used wherever older VW specifications for petrol engines are required, for example. For
diesel engines, specification VW 507 00 can also be used for the corresponding older
diesel specifications. R5 and V10 TDI engines up to model year 2006 are the exception.
These engines must be filled with an engine oil according to VW 506 01 (TITAN
Supersyn LONGLIFE PLUS SAE 0W-30). For VW engines that require VW 508 00 / 509
00, engine oils with specification VW 504 00 / 507 00 can currently be used as an option.
TITAN GT1 LONGLIFE IV SAE 0W-20
The new TITAN GT1 LONGLIFE IV SAE 0W-20 was approved by VW in accordance with
VW 508 00 / 509 00 and is now available to dealerships and workshops.

Of course you should. Same engines are designed first and foremost around 5W40 oils. They are still recommended to use ACEA C3 in EU and ACEA A3/B3 B4 in Russia, Ukraine and other former Soviet Republics as well as rest of the world.
Now, only reason why VW moved to 0W20 in the US is CAFE and aiming most of their line up to soccer moms.


VW and Volvo(new models), recommed 0w-20 in EU

Castrol Germany for 2.0TSI (EU model) recommends Castrol Edge 0W40.

Let's say that is all true. SO VW designed oil pump just for BUDACK cycle version of EA888 compromising other parts of the engine so that oil pump could work?
VW has some serious issues figuring out what they want in the U.S.

Yes they state the same thing here 5w40 or 0w40 for 2.0tsi but those are for the other slightly older engines engines, unless you show somewhere showing for the new E888 GEN3B Engines...

Castrol home page have much error. Service fill is 0w-20
 
I wonder if VW realizes how many customers buy elsewhere because they don't want to
Deal with specialized oil , its cost and for now its limited availability.....

I'm thinking, why bother with all of the stupidity? We are in the USA. Specify API oils!
 
yep thats exactly what i was thinking as well but people love these cars so much and everything about them they still stick with the brand ya know.
