Both my F-250 and F-350 with V-10's experienced that...

We are a little over 15k on our 2016, and we were commenting on our return home this weekend, that the engine seemed stronger/smoother and possibly quieter (wishful thinking) .. and, transmission has gotten 'smarter', so to speak.
On our trips this summer, we have not checked gas mileage...might be interesting to find out if we are over 10 !
