Wow. Today I took a nice long, leisurely Sunday drive, total of a 3 hour trip, to the lake where I drove most of it manually, not using cruise, and taking a windy, hilly, 2 lane back road on the way up, and took the highway on the way back, using cruise where I could on the highway. I got 26.1 MPG on the way up and 27.2 MPG on the way back. I thought I was doing good until I read this. But also, I did notice that I used almost 1/4 tank of gas and based on miles driven I thought it should have been less overall, so I was already questioning how accurate the calculated MPG was before I saw this. New plan! Fill up, count miles driven, then divide to see what I actually get.
Oh, by the way, the truck currently shows my overall average at 20.2, and I’ve put about 700 miles on it total.
