Don't want to intrude on your
oil plans, on my dry sump after break in I have finally settled on a Mobil 1 0w40
oil, rated with european standards and I think it was recommended for some of the current dry sump production cars. Numbers looked good and I haven't noticed any loss of
oil pressure compared to my previous brands & weight at temperature. Auto parts stores charge a pretty penny but you can pick it up at walmart for $23 a jug.
