0W-30 German Castrol, available at Pep Boys/Autozone. 0W-40 Mobil 1, available at Everywhere. You can't really go wrong with either of these.

Mobil 1 HiMiles, 10w-30 for summer. Great product for a modest price.


Edge 5w-30 did the best of any oil I've seen in a 1.8t

a 502 or acea a3/b4 5w-30 or 5w-40 would suit the 1.8 better year round. m1 10w-30 is not acea a3 although the hi miles 10w-40 is. but 10w-xx is not a good match for a turbo imo. m1 0w-40 is the easyest oil to find, the new castrol is around along with many others. the mann 940/25 filter for the passat fits and will bring the capacity to a full five qts..

Mobil 1 10w-30 HM is ACEA A3, one of just a few 30 weights to make the +150c High-Temp/High-Shear rating of >3.5cP, like German Syntec and MaxLife Synth, BMW's Castrol 5w-30....and all the Euro 5w-30s.

Specifications and Approvals

Mobil 1 High Mileage oils meet or exceed the requirements of: 5W-30 10W-30 10W-40
ACEA A1/B1,A5/B5 A3/B3,A3/B4 A3/B3,A3/B4

Not that it matters, I've gotten great DOCUMENTED results from A5 oils (common 5w-30 synths) it's just the same "quality", just thinner, and better.



Shall I post some UOAs?
