Reset the MPG readout, drive for a hundred miles or so, then check again. Personally, I set my default display to MPG. The more miles you drive, the slower any changes in actual current mileage affect the average MPG readout. It displays overall average, not current average.KEVSTER wrote:I have noticed that my onboard computer now says 17.3 average on MPG befor it was 18.4, I noticed this after the snow went away.. was driving in snow for 2 weeks here deep stuff, and I have the Yokohama A/T on also. The 17.3 figure stays the same ,you would think it would go up or down a digit or two.. any thoughts?? I have only 7400 miles on my ride.
