I tried to find the article mention below by Gil Wistrup at the Jaguar
Association of Central New York website without success.  The link is for
Jaguar Cubs of North America;

Castrol GTX 20W50 is widely recommended. An article in the March 2002 British
Marque written by Gil Wistrup of the Jaguar Association of Central New York
strongly advises the use of CG-4 (compression ignition) diesel rated engine
oils which contain a significant amount of ZDDP antioxidation additive.  CG-4
engine oils contain about 80% more ZDDP & about 50% more detergent than SJ
(spark ignition) rated oils.  Itbs supposed to be excellent for cars that
sit idle a good part of their life.
