I use Mobil-1 15W50 (red cap) in all my vehicles
including the S4, mostly from habit. I know that
Audi specifies lighter oil for the S4, but I suspect
that is to try to increase gas mileage. My '91cq
has 160k miles on it now, most of it with the 15W50.
I did try 5W30 on that car when it had 120k, and it
leaked oil badly and burned up a quart every 1000mi.
With 15W50, it is more like 1qt. every 4000mi, which
has been consistent since I got the car in '92.
Synthetic oil is pretty robust, I think either weight
would be fine, though track days at 100F might
justify the heavier wieght. I'd shy away from
anything 0W-x for anything south of the arctic circle,
but just my opinion.
'91cq- modified, still slow
'00S4- stock, very fast
