Castrol Euro in my mk6. It meets the VW spec according to the bottle. I've been using only that for 9+ years, changing oil at 10k miles or 1 yr, zero sludge, zero problems, original turbo, good compression, good oil pressure, etc. IMO it's very good oil.

Castrol euro 540. Tried liquid moly and a few others but my car burns them for some reason.
I highly recommend Castrol Edge 0w20 and Castrol edge 0w20 high mileage oil for your vehicle which requires 0w20 508.00 oil. 508.00 burns a lot. And I looked the additive in it. It is very cheap mixture. When I use regular Castrol edge it gives less oil consumption. Highly recommended for you.
Castrol gtx 20w50
I live in Oregon. I run 20w50 valvoline vr1 or Castrol GTX.
ive used Castrol in all my cars ive owned, One being a Kia, and then two Hyundai Velosters (VT and my N), so Castrol Edge 5w30 is what mine gets
Avoid. Tried it, it burnt off very quickly. Back to Castrol with my tail between my legs.
I've been using 15w40 diesel motor oil in the AMC/Jeep flat tappet engines for nearly 20 years. Castrol makes a line called GTX Classic that's formulated for flat tappet engines as well
I use Castrol Magnatec A3/B4 10W-40 part synthetic. 3 years now and no problems.
5W-30 Castrol C4, never fails with my Clio. DPF is safe and sound, no soot, no weird smells.
