I just had my 2nd oil change done today at my Ford dealer. I supply them the OEM filter and Rotella T6 5W-40 and the kids do all the work and I watch over and chat with them about the truck. $33 out the door for that, and saves me all the hassle of doing it myself.
On both oil changes my truck was tracking to just beyond 10K oil life. Did the first change after 8,172 miles and did the second change today at 15,658 miles (7,486 since last change) with 25% oil life remaining. I had 18x,xxx miles on my 2010 5.4 KR when I traded it in on this 2018 3.0 KR, and I always followed the truck oil life remaining % on that truck and ignored mileage, and tried to change oil before I got down to 15% oil life remaining.
My strategy on the 2018 3.0 will be to change no greater than 7,500 mile change intervals, no less than 25% oil life remaining, and potentially change sooner if I am doing a lot of towing (by a lot I mean 1,500+ miles towing since last oil change--which will be my situation on this current oil).
I put on 22K miles per year, so at 5K change intervals I would be getting a change every ~11 weeks or so, and with 7.5K change intervals ~17 weeks between changes. However, when you do the math, it is only like another ~$75-100/year to do 5K change intervals for me instead of 7.5K change intervals. I just have a hard time mentally going in for an oil change at 5K intervals when truck display shows 50%+ oil life remaining. Having said that, I know not everyone's truck is tracking to 10K change intervals, so for those folks shorter change intervals are likely warranted.
