What kind of oil for S4?

What kind of oil for S4?
The manual says 5/40.
My GT2 uses 0/40.
I would like to use the same oil for both cars, I currently have a case of Mobil1 synthetic 0/40 for the GT2.
What weight of oil are you guys running?

I believe my RS4 is the same weight as your S4. I didn't see this thread earlier or I'd have checked what's in my garage (I have some Mobil 1 in there). I'll get back to you tomorrow, but I don't think 0W-40 will hurt...

This is what I remember from reading about oils over the years. Someone correct me if I'm wrong.
The first number concerns viscosity when cold (i.e., at start up.) The lower the better. The second number is viscosity when warm. I dont see how 5w40 could ever be better than 0w40 except for its affect on your wallet.

But it is also the best. I wouldn't put anything but 0W-40 in that RS4 brother.

Can't go wrong with the best
