I filled up today and driving home the DTE was dropping at a rare of 1 mile in less than quarter mile driven. It went down 24 miles in approximately 6 miles. I drive conservatively and even more so when i saw this happening. Does any one know what could cause this
it's a 2016 Fx4 5.0 with 194k on it.

 

You weren't leaving a trail of gas behind you like some crackhead done drilled your tank were you? Lol
