How did you determine the Ford PSD comes from the factory with a 10W-30 oil? Did you pull a sample with low miles and send it off to be analyzed?quote:

Ford PSD comes with 10W-30 oil with a slightly higher moly number than the normal MC 10W-30. The 10W-30 is also a lighter oil than the recommended 15W-40 for the 6.0L PSD.
Thank all the people who buy Syn and change it well under 10k.quote:
