Audi S6 v10. 502, 504 or 507 oil?

What do the Audi dealers use? I presume it will be Quantum from TPS?

I read in my manual that if it's switched to annual servicing (which it will as I drive short distances), 502 oil is acceptable.

Previously, I've always used Quantum LL3.

I do however have some Castrol Magnatec 5w30 C3 which is 502 rated. This will be fine won't it?

That will tell you the acceptable oils/specs for the 2 service regimes. Dealers use the same longlife oil even on annual servicing - been like that for years now. Given the engine I'd be tempted to stick with longlife stuff with annual changes

I don't think you want 507 - it's intended for DPF equipped diesels

I'm going to opt for Quantum LongLife III.

Just called TPS, they've advised that they expect and offer to come on soon.
