Today I drove some miles on the highway and averaged (an indicated) 41.0 mpg with 87 fuel and AC on and two passengers and 3/4 tank of fuel in 86 degree temp. I will keep a log and try 93 fuel also, and check tire pressure.
Question - when I reset the average mpg, how come it starts at about 25 mpg and then slowly goes up to 40 even if I push reset after it is at cruising speed? It should start at about 40 mpg since I pushed reset after I was theoretically already getting it. It seems like Ford did not implement this feature correctly.
