I sent an email to Red Line asking them why the 5W-40 did not have the moly content like their other oils. Here is the reply I received today from Dave at Red Line.

Johnny,
Thank you for contacting Red Line Oil, the moly has been eliminated from the 5W40 and 15W40 as both are designed to satisfy the new CJ-4 diesel engine oil requirements, specifically limiting the sulfated ash to ≤1% for emission system compatibility and continued performance.
Regards, Dave
