How to optimize MPG - thoughts?

[Plati]

I really didn't think modern engines had any break in period ?????

So, I looked in the Ownrs Manual for my 2014EL and lo & behold

It took mines 5k miles to break in

I have 1800 mi on my month old '19 Platinum 4x4 with tow pkg and get about 16 city. I record mileage every fill. I have noticed that the mpg calculator on the trip meter is off high by about 1 mpg. On my old Explorer it was closer to 0.5 mpg and sometime read low. I haven't taken any long road trips that used a full tank yet, but that will be coming in the next 2 months.
