Upcoming VW 508 oil spec

[dparm]

I'm seeing references to it here and there but can't locate any definitive information. Apparently VW 508 00 is being developed and is focused on fuel economy with low SAPS.

Has anyone heard anything on this? What markets and engines is this being targeted at? Any idea when it will be released? What ACEA spec is it modeled on?

I've seen mentions of this spec going as far back as 2010, but no details whatsoever, apart from what you've already noted.

504/507 is already focused on fuel economy and Low-SAPS.

if they are working on a "508" spec... then it would be modeled on the next Euro emissions levels. Once that fully established, ACEA standards will follow.

These specs still call for HT/HS viscosity of at least 3.5 cP, so that effectively limits any serious fuel economy benefits. Maybe this new 508 spec would allow lower HT/HS limit?

VW had also, 503.00/506.00/506.01 specification which was a 0w30 oil, with a "lower" HTHS spec, 2.9-3.5

Are these still active VW specs? Afton Handbook does not list them anymore for some reason.

By the way, these are low HT/HS, but not low SAPS.

Curious to see how the engineers get it done with an hths <2.9

Yes, but I believe the only engines that spec 503/506 are the VW 2.5 R5 TDI and the VW 5.0 V10 TDI.



VW 503.00
Long-life gasoline engine oil for VW cars with WIV (system for longer service intervals). Also meets ACEA A1, SAE 0W-30 or 5W-30 specification.

VW 506.00
These oils are suitable for diesel engines with extended service intervals of up to 50,000km / 2 years. Not for use on engines with a single injector pump. Oil change is indicated by the electronic service indicator. Viscosity is SAE 0W30.

VW 506.01
These oils are especially for "Pumpe-Düse" (unit injector or "PD" engines) running on extended service intervals (30,000 - 50,000km / 24 months). Oil change is indicated by the electronic service indicator.




Motul sells a Specific 503/506 0w30 (TBN of about 10, HTHS of about 3.1) and says:
-Fuel Economy Engine Oil specifically designed for extended drain intervals (WIV) of new VAG (VW,AUDI, SEAT and SKODA) Gasoline and Diesel engines from MY2000.
-For VW, AUDI, SEAT and SKODA Turbo Diesel Unit Injector engines and fixed drain intervals at 15000 km an approved VW 505 01 product such as MOTUL Specific 505 01 502 00 505 00 5W-40 is preferred.

Ravenol still makes a 503/506/506.01 approved oil. Although it isn't specified for the VW/Audi 2.8L 30V, it is recommended by Blauparts.

I belive Fuchs and Gulf also supply to these specs.

Fuchs don't tell much when i was looking for specs, unless i was just not finding it. manufacturers make it hard to compare products on purpose

Their solution is Titan Supersyn Longlife Plus; the complete list is here.
They also have a useful and comprehensive applications guide.
