Here is my latest UOA on my 2006 Lincoln Mark LT truck. It has the 5.4 V8. The oil had been in the vehicle a little over 14 months, and that is why I changed it. It appears that it was in good shape, and could have went longer. Previous oils were Castrol Syntec (previous fill) and Valvoline Syntec. I went with Motorcraft 5W20 and a Motorcraft filter this time to see how how Ford's oil compares. My next run will probably be some leftover Havoline 5W30 SM formula even though the vehicle specs 5W20. Any feedback or comments are appreciated. Thanks.
