I think Volkswagon and Mercedes specifying Mobile 1 has something do with
squeaking out an extra .5 miles per gallon on mileage tests and being able
to offer extended times between oil changes.

'I have no interest in Castrol, but in my lifetime I have met several guys

than any oil they tested including their own. None of them worked for
Just an FYI.
I, too, have no dog in the oil brand fight, but my first summer job in
was as gofer for a Porsche, Mercedes, BMW, Jaguar
(and occasional new Ferrari, Ford GT, and 427 Cobra special order)dealer,
the shop used Castrol exclusively. That how I got into the habit of using
My Tiger is engineless at this point, but my '87 BMW 325iS uses BMW
by Castrol), my '00 325CI coupe specifies BMW brand or Castrol Syntec(I use
the Syntec at home).
Volkswagen specifies Mobil 1 for my '07 Golf/Rabbit, and that is the one
I make to using Castrol. Admittedly, it has more to do with being a long
habit for me than research.
