Best Engine oil for Audi A4

Valvoline SynPower Full Synthetic 5W-40, VW502 approved. I use it in our '07 A4 (over 100K miles) and plan to use it in our '16 GSW.

I run the T6 in my 2.0T FSI.

I have noticed my car is "running better" with the Rotella, and i have not had to top it off at all compared to running Motul 5w40 i had to add quite a bit over my OCI.

Speaking only for the 2.0T in our B7 A4...it burned nearly 1qt of Castrol Syntec 5w40 during a 5k interval. Before and after that interval I ran M1 0w40 for 5k, and it burned next to zero. Needless to say I'll continue to use the M1.

I switched to Mobil1 5w-30 shortly after purchasing my 99.5 1.8T and I haven't had any problems, as a matter of fact my cold-weather starts noticeably improved and oil temperatures seem to be consistently lower during normal operating conditions.

AMSOIL BABY, all the way. 10w30 Turbo oil and filter every 12,500 or 6 months whichever comes first. Out performs all other brands!

I switched to Mobil1 synthetic. The factory fill oil is 0w30. I replaced it with Mobil1 0w40, it complies with all of the specifications, and is not that expensive.

I've been using Amsoil on my '02 A4 1.8T. Converted it over as soon as I could b/c that little hamster gets hot during the long summers around here. Car doesn't burn a drop of oil, of coure it has only 29k on it.

I am using Castrol 0w-30 Synthetic. The Castrol distribuitor here in my country has a Audi A4 and he recomend to use 0w-30 synthetic. This oil meet VW specs. My dealer also recomend the same.
