Thanks Dennis.  I was suffering from a severe case of craniorectalitis and
was too lazy to go out and look at a bottle.

Are you suggesting that the now kinda popular idea of running diesel oil may
not be a good idea?

|I have never seen Castrol GTX in 10 or 15-50. The norm is
|20w-50. This is an oil for the modified and collector car
|crowd. Very good stuff and will hold higher pressure than a
|15w-40 Diesel oil.

|That seemed to be something of a consensus after the
|discussion of zinc additives, or a lack thereof, a month or so
|ago.  I've been using Castrol GTX 10w/50 (might be 15,
|thinking about it), and am considering changing when I next
|change oil before I leave Phx for Seattle in early September.
|
|I'm looking forward to someone taking me by the hand and
|saying, "Do it this way" (and being correct about it, of course).

||So, are folks recommending that we run a diesel oil in our vanagons?
