I know the oil filler cap says Castrol is recommended, but does that mean that's just the company that paid Audi the most?

Audi supposedly 'developed' Longlife oil with Castrol but it's not about the viscosity, it's about the specification.
Audi [and all VAG group cars] quote the VAG specification. Confusingly, this has changed over the years but 'sort of' boils down to diesel/petrol engine oil specs.
I think I'm right in saying that 504.00 and 507.00 are the specs. these days which replace all previous versions.
Mobil 1 is a brand - you'd still need the get the 'right' Mobil 1 for the S8.
I'm using Mannol 7715 OEM which is a German brand that is 504.00 and 507.00 'compliant' on the label, is 'Long Life' and is also appropriate replacement for 502.00, 505.00, 505.01, 503.00, 503.01, 506.00, & 506.01. [My A8 is supposed to use 506.01 for Longlife in my 3.0 diesel according to my 2004 owner's manual].
In my mind, if the oil meets the spec., there's no 'better' brands, only more expensive ones
