OK, gotta share parts of my dialogues with Castrol and my servicing dealer:
Me to Dealer:
Want more info? Of course you do J
“I contacted my VW dealer to find out if this was what he used. He says the oil comes out of large barrels marked Castrol, but cannot tell more than that. Is it likely this is what he uses?
The parts department there sells quarts but of VW branded oil. The dealer thinks this is rebranded Castrol. Is that true?”
Thank you for contacting Castrol North America.
- Castrol used to manufacture a few products exclusively for Audi/Volkswagen until late 2021.
- In 2021 Audi/Volkswagen began manufacturing their own oil meeting Audi/VW spec 508 00 and 509 00.
- Prior to 2021 the Audi/Volkswagen dealership would have been using a product called Castrol EDGE Professional LL IV FE 0W-20 for vehicles needing the Audi/VW spec 508 00 and 509 00.
- (All Castrol EDGE Professional products are Dealership only)
Castrol EDGE 0W-20 LL IV replaced EDGE Professional LL IV FE 0W-20 in late 2021.
Castrol EDGE 0W-20 meets the Audi/VW spec 508 00 and 509 00 and may be used in your vehicle.
Thank you again for contacting Castrol, we value your patronage!

Dealer replies ( I was concerned he would think I'm nuts at this point
Awesome info! #TheMoreYouKnow!
I will admit, you made me question everything I thought I knew about our oil supply haha Turns out there are 4 different weights we stock in different capacities. 0w30 and 5w30 in drums, 5w40 from suspended lines in each bay, and
0w20 in 2 pumps on either side of the shop. Things are far more complicated than they were when I was a technician 5 years ago! So apparently, I was incorrect on the 0w20 and rather than assuming, which is what got us here, I chased down the parts manager and found that they do come in separate drums I can't see, and they are in fact labeled VW! Mystery solved and confirmed.
Thanks for the adventure
So now I know
Seems VW branded is the new goto 508 00.
