I'm using Castrol Syntec Euro formula which is a 0-30 oil. I've been doing oil analysis with every oil change since I got the car. This change was a short interval with just 1400 miles on the oil between changes. Right in the middle was a track day where I did about 130 miles on track, six 20 minute sessions. I think I was seeing peak oil temps in the 240s with very quick recovery back down below 220 during cooldown.
Castrol A747. The only failure I've ever had was down to incorrect assemble. Smells lovely too!
I use Castrol Syntec 10w-40 in all of my VR6's and change it around 3000-4000 miles with oil filter (Meyle, Hengst or Topran) I use it in my MK4 and even in my old ass MK3 and never had any problems whatsoever. My MK3 VR6 that a sold a few months back, a.k.a. The Silver Bullet, has over 150K miles on the odometer and still counting and she runs like a beast. The lifters are ticking a bit loud but that's common for any high mileage VR6 engine.
Vw recommends Castrol I wouldn't use anything else
Castrol Syntec 5w40 is stout enough for the 10,000 mile oil change.
I've used the OE spec Castrol syntec 5w40 since I bought the car brand new. Do my own oil changes every 5k with the stuff and no issues.
I bought a liter of 507 (don't use anything else) Castrol SLX, and 15K later... still haven't broken the seal or had the level go below full.
Castrol EDGE Professional LL03 5W30 Engine Oil. Meets VW spec 507 and is what VW recommends.
I am also running castrol gtx 10w40 regular oil with the Lucas oil stabilizer on my vr. I had some light smoking issues before while running synthetic and switched over and it completely stopped.
I did notice lifter noise with the 5w-40 so decided to go with Castrol Syntec 10w-40 and it made quite a bit of difference in quieting down the lifters. I use a Mann filter. After i get the engine flushed on my VR swap using ****ty conventional oil, i'm going to run Castrol Syntec 10w-40 in it as well. Lots of people recommend 5w-40 or 0w-40 for the VR but i've found 10w-40 works well and my oil temps seldom exceed 208*.
