inquires about engine oil
My AUDI A4 was installed EA888 GEN3 Engine ( 140KW, Engine code CWNA). I was recently noticed that this engine perhaps apply Audi B cycle tech, Audi suggests to use 0W20 oil and standard meets to VW 508. can anyone tell me whether i can follow this oil?

The factory user manual suggest to use oil standard meets up to VW 502 or VW504. But, the Newest Audi maintenance schedule introduces the engine with B cycle technology should use 0W20 viscosity as per VW 508 oil standard, especially Audi is using B cycle to EA888 GEN3 engine with low power already, I knew my Audi have EA888 GEN3 engine, but i couldn't certain whether I should use 0W20 oil.

Audi/VW recommendation -- "B-Cycle and 3.0 Turbo (S4, S5, SQ5) Gasoline Engines:Audi oil standard VW 508.00". Yes, 508.00 is 0W20 and it can save gas to match the whole purpose of B cycle engine which is to save gas. However, the 508.00 standard has a lot more than just save gas -- it's the additive package to keep the engines clean. Otherwise, they wouldn't let a thin 0W20 oil be used in high performance 3.0 Turbo engine for those S model cars. If I were you, I would stick to the Audi's spec and use 0W20 oil which meets VW508.00 standard (note: not all 0W20 oil meets VW508.00 spec). They designed the engine to handle the thin oil.

And Minmet's post is accurate:

Our B9 S5 cabriolet came from the factory with a 504.00 label in the engine bay. They must have run out of the 508.00 ones at Neckarsulm, or not had any there at the time - cabriolet the only version made there, all others at Ingolstadt. Zheng pretty smart to double check!

The 502 (5w40) spec is dead now. You'll have 508 (0w-20) for the B-cycle motors and 504 (5w30) for the rest in the US. Factory fill on everything but the B-cycle motors is 0w30 (also a 504 spec).
