Engine oil Castrol or OEM Audi

But as a fellow 7.5 owner i switched to 15w-40 when going stage 1 because where i live temps regularly even in winter are around 98-105 degrees and i was finding i had to top off the oil every 1,200 miles, since the switch to the thicker oil ive done 2,500 and the level is exactly the same

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.

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

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.

Castrol makes a Edge Euro 5w-30 and 5w-40 that is LL-01 and ACEA A3/B4, it's not going to meet the later LL requirements because it's higher viscosity and not as fuel conserving, also not low SAPS so potentially it could contribute to more intake valve buildup

I used castrol edge on my last change but I don't like the way the oil looks after a few months of driving. Of course it was extreme temperatures down here in South Texas. Wonder if the extreme heat caused my oil to look kinda jello looking haha.
