This is my fleet company truck. It may be mine someday when it is retired as I can purchase it from surplus therefore I did a UOA on an engine that isn't currently mine. The use of this truck is a daily commute to work 50 miles each way and an additional 25-50 miles a day on average of oilfield access roads where I may have the truck running for 3-4 hours straight while doing my field visits(Keeping the laptop cool in the AC). Farmington NM is Dry and dusty so I was happy with the filtration and wear on this engine. The oil is Bulk Castrol Syntec 5w20. The interval will remain at 4k with it for the remainder of its service in the fleet. I struck some of the comments. I had a conversation with Blackstone earlier concerning my wifes Explorer report and in an attempt to make the comments more personal they mixed up the F150 as hers.
