As the topic says, a FYI post really - I originally posted this on [censored] but think it is useful to have in the archives so to speak:
Straight out of Audi Driver August Edition:
Approved Engine oils for Audis
503.01 Spec:
A new oil specification specifically for the RS4, S3, 225 bhp TT, Passat W8 and Phaeton W12
Castrol Formula SLX 0W-30
Mobil 1 0W-40
Shell Helix Ultra 5W-30
Fuchs Titan Supersyn SL 0W/30
Valvoline SynPower MXL 0W-30
The S3 will come with Castrol Formula SLX 503.01 spec oil from the factory
There are other Formula SLX oils for different specs, ie 502.00 etc - so make sure you get 503.01
SLX Longlife II meets 503.00, which is for variable servicing and the 'old' S4, but as I have said, not RS4, S3 or TT
Thank you
