This is my latest run using Castrol Syntec (SM version) on my 2006 Lincoln Mark LT (Lincoln version of an F-150) during the past 7 months. Previous run was Valvoline Synpower. Oil was changed to Quaker State U.D. 0W20. Comments are welcome and appreciated.
Comments from Blackstone Labs were as follows: We were hoping for lower wear metals, and that's what we found-sort of. Iron improved nicely and the other wear metals essentially held steady. Iron typically tracks with time on the oil, so it's certainly unusual to see it lower after a longer run, but it's nothing to complain about. All in all, this engine appears to be in great shape at 74868 miles. No fuel or coolant was present and air and oil filtration couldn't be much better. The TBN was strong at 2.6 showing plenty of active additive, less than 1.0 is considered a low reading. Try 7,000 miles on the next oil.
