and if it does is it 1100ppm or better???
The real problem is that the 15W-40 or 20W-50 is too thick for good cold startup oil flow. 80% of wear occurs at startup. A 5W-30 with ZDDP will protect better.
Mobil 1 extended wear with the gold cap bottle.

Actually, now that I check the 5W-30 extended performance has 800ppm. (which should be good enough) For 1200ppm, you have to go with the 15W-50 extended performance. They also make a 0W-40 which has 1000ppm, but I haven't seen that in stores here. That one would actually be the best. It is approved for Porsches and Vipers.
The Rotella T is conv. correct? Any benefit to running the synthetic 5w40 besides the easier startup as far as the ZDDP is concerned?
