Rick asks lots of Z3 questions, one of which I'll try answering:

If you live somewhere where there is a PepBoy's chain store.. go to
the oirl department and look for Castrol GXR - which is a 15-40
fleet, diesel rated oil. Cost is the same as GTX (usually) and it
is an even better oirl. (I just like to spell it that way!)..
Every - yes - EVERY rating on it is one rating higher than GTX.. (and
every other quality oirl I looked at). A mechanic friend recommended it
to me a long time ago - he buys it in bulk (300 gallons at a time) for
use in Ferrari's, Mercedes V8's with the single row timing chain, and
BMW's where people know to ask for it. He pays more for it in bulk than
it costs at PepBoys when on sale.
At this point - whenever P-B's has a sale on GTX, I march in and buy
a case of GXR (same price) - and it is currently used in my Bimmer and
both my Beemers. My mechanic claims he has never seen any oirl related
engine damage on engines using it..
Good stuff - and a good price.
