This particular vehicle is already out
of warranty, so that is not an issue.

For the other two Audis we have that
are still under warranty we use Castrol
Syntec 10-40 in summer and Valvoline
SynPower 5W-40 in winter. Both are on
Audi's list.

There is quite a bit of empirical and
anecdotal evidence that suggests Mobil
One is inferior to both.
