PO indicated my 200q20v grew up on Castrol dino oils to the ripe old age of
140K by the time I acquired it.  I've kept up that practice for another 90k
miles so far.  I change oil/filter at "about" 4k.  I don't really see any
reason to pay for synthetics to be used in equipment designed before there
were synthetics.

I use dino Rotella in my diesel tractors.
