Correct me if I'm wrong, but I believe Mobil Exxon suply lubes to Castrol
Nope, you are very wrong. Mobil have never supplied Castrol. Mobil is part of the Exxon Mobil Corp, which includes the Mobil and Esso brands. Until a few years back, Castrol was a wholly independent brand, but is now part of the BP "empire" which includes BP, Amoco, Burmah, Castrol, Duckhams & Aral.

. . . . I used to work for Mobil Oil and without a doubt Mobil 1 is one of the best oils available.
That is an extremely generic and "wooly" statement.
Mobil 1 is shyte for compliance with later OEM requirements.
Yes, in its' day, Mobil 1 was a very good lube, about 15 to 20 years ago, before the days of OEM specs, when the likes of the original API, and the later ACEA generic specs were the norm. Unfortunately, todays OEM specs are considerably more rigorous than the pathetic API specs, and the improved ACEA standards, and Mobil oils just havn't kept pace with modern lubrication demands.

Just dont use normal Mobil 1 for AVS as its (best) life is approx 13-14 months.
Didn't I say that up there ^^^ ??

So it is perfect for a 10,000 miler or annual service.
No it is not, as it doesn't comply with any of the modern VW standards (even though it lies on the bottle!).

Which is why they made the Mobil 1 ESP, same as the Castrol SLX Longlife II ( now called edge).
Again, you are wrong. The Mobil 1 ESP is a 5w30, and has been tested to meet the 504.00/507.00 approvals. These are LongLife 3 approvals, not LongLife 2. The two differing standards, in certain engines, are NOT interchangeable.
