First let me rekindle the fact that I am not Audi V8 savvy...

but in general, as I learned on this list over the years, the oil temp
should get over 100 C in order to boil off condensation.

also, on all my, admittedly cylinder-starved (only 5! no V!) Audis, the
oil is always hotter than the coolant when the engine is warm.

Anyway, if 60 is a "normal" oil temp for an Audi V8, then my comments
have been, as usual, spurious and of dubious value evne as
entertainment...
