Engine oil Castrol or Motorcraft

A definite 'no' on that. VW says no and it's been shown many times. The factory fill is plain old off the shelf oil (generally Castrol).

Have my best experience with Castrol 0W30 (European $8.99/qt) Minimal lifter noise and run it 5k between changes. Also, use OEM oil filters.

i tryed the castrol edge sport 10w-60 and its working great (very smooth & quiet,etc... any way better than the 4w-40)

ive always used motorcraft diesel oil. 10w30 in the winter and 15w40 in the summer.

always ran castrol gtx diesel 15w-40 in my old 1.5 no real reason but when i bought the car it came with a case in the trunk so i just kept at it. motor never had a problem, and it ended up getting swapped into my buddy's rabbit and boosted.

Edge 5w-30 did great for me. It's a great product, turning in the best 1.8t UOA I ever saw. There are PLENTY of great products dirt cheap on our shelves. I personally feel SynPower is most worth of my money, on a full price basis. Otherwise, I'll buy any other NAME BRAND synth when its' $4 or so. I actually nabbed a bunch of Quaker State 5w-40 from BigLots for $4ea. QS is a sleeper oil, esp at the right price. High moly too, great for break-in.

I used Edge in my APR 2.0TSI over winter, did a lab report and wear was minimal, actually the same as a Motul 5w-40 sample from the same mileage.

GC 0W30 is PAO based oil. PAO and Ester based oils are much more stable and clean engines much better. People who need 502.00 approved oil simplly LOVE that thing!

I am sticking with 0W30. Plus, it is better for cold start, which is one of the most important things!

Castrol 0W30 Made in germany, or as it is best known "German castrol." It is "thick" 0W30 more going toward 0W40. It is thermaly very stable oil. I used it on Passat B5.5 1.8T (2005) and there is more then obvius difference between "GC" and regular Castrol 5W40. GC so far is the best I used it.
