Well that seems to agree with what I've read others have concluded from their computing also. The display shows about 1mpg less than actual. It's good to hear another confirmation of this. Thanks.
That means I likely get about 24mpg mixed driving. Sure beats the 13-14 mixed I got in my Dakota RT.
Me too. However, since I replaced gears, I've had two occasions where the computer was within a couple tenths below actual MPGs. Most of the time it's still 1-1.5mpg too low. My last tank reported 24.8mpg, but I calculated 26.68mpg.
I think what happens is that it over reports fuel usage. I reset the MPG meter and the trip meter at each gas up and in the trip meter menu it shows fuel usage in gallons. It's always higher on the computer than what I put in the tank so I think that's where the error comes from.
My 2012 v6 base manual, 5000 miles, also consistently reports 1-1.5mpg below actual at least on highway trips, usually don't track local driving.
Just got a 2013 Explorer so far computer was actually 1 mpg under then accurate next time for the 2x I filled up. It says not to track mpg until over 1000 miles.
My 2010 Toyota RAV4 was always spot on with the mpg comp. vs. calculated....
Mine is usually within .5 mpg. I use Kiwi Gas Manager on my iPad to keep track of my mileage and other data for my main two vehicles. I like being able to graph my mileage and costs.
FWIW, since most/all of the replies have come from V6 owners, my GT's computer also typically under-reports by about one MPG, sometimes a little more.
IME the more consistent one's driving is, the more accurate the on-board computer is. That is, when a given tankful is all-city miles, or all-highway miles, the dash readout tends to be much closer to the actual calculation than if I drove, say, 75 miles in town, then did a 120 mile road trip, then did another 60 miles in the city.
19.2 is my best
muat of got a bad one
or when i drive i pound on it to much
it now has about 4600 miles on it.
