VW / Audi reportedly changes oil supplier

Who else remembers all the VAG engine oil sludging issues 20 years ago? We've come so far!
That’s because dealers were using regular dino oil in the early MK4’s that had a new 10K OCI. They weren’t using the proper 502 spec synthetic.

That was issue with oil itself.
Yup. Same issue with Volvo's at the time. Conventional oil + turbo = clogged PCV systems.
"But we used Castrol!!!"

The reason was that VW North America wanted to lower the cost for drivers. In Europe, they used VW 502.00. In US they used, well, whatever. However, even regular synthetics did not do well.
TSB fixed that in 2001 with a larger canister filter and VW 502.00.
When I bought my Jetta, I was told to only use Castrol 5w-40 oil that met the VW 505.01 specification. I looked at the bottle and it clearly said it was a synthetic blend. So, from 10k to 100k miles I used Motul Specific 5w-40 that met the 505.01 specification. It was a Group III oil. After 100k, I have used Mobil 1 TDT only. I have religiously changed the oil every 5,000 miles. At over 340k miles now, I think the record says I have been doing it right.
My model of PD TDI is notorious for wearing out the cam. Mine is still original. My opinion is the low grade Castrol oil and 10,000 mile oil changes were the problem. There is no chance I will use Castrol in any of my ICE cars.

There are different flavors of Castrol, same like different flavors of Mobil1.
0W30 Edge is IMO still best Euro oil for gassers.
VW505.01 was always synthetic oil. How Castrol advertised it, is marketing thing. I had 1.9tdi PD vehicles in Europe, and they generally did exceptional on any VW505.01 5W40 oil, including Castrol.
In 2005 Castrol 505.01 was NOT a synthetic, only a synthetic blend. It said so right on the bottle. It may have been different in Europe. The Motul Specific I used came from France. I paid extra for a better oil.

Ok. They must had confused VW505.01 approval requirements and printed it for no reason.
But, HTHS of 4.5cP according to this thread and KV100 of 14cst, indicates hefty amount of PAO, not just any synthetic base oil.
In the interest of science, I bought a qt of this magic elixer for $12.50, plus tax. I'm underwhelmed to say the least - kind of like expecting a date with Brooke Shields and getting Albert Brooks in a dress instead ...

Interesting. I took Wife's Golf R in for a recall and tires, and the Service Advisor called me and suggested "BG brake treatment"...the answer was a firm "no". I dint even ask what it was and I will bleed the brakes myself or use an indy thanks.
Looks to be just a fluid service - really should do it every 2-3 years anyway, I bet that's all they were selling.

That’s cool I like that Mobil is giving Castrol some of the market and let them have the low bid. 
. I also don’t own an Audi or vw but like to be informative on all sorts of topics.

Well, at least Castrol won't have to make their bottles black

You're speaking of the "pink" banner A3/B4 API SL one, correct? If so, I agree it's a good un'.

Edge 5W30 A3 is also SL. Pink one was previous version of 0W30. There is new version of 0W30 and it is also SL. Probably SP 5W40 additive package inside.
Orange banner? Can only seem to find pink banner one on the 'Zon.
