I am guessing that the ECU judges the distance you travel by what the speedometer says, and the speedometer isn't precisely accurate so you are bound to be off by just a few mpg.
For the most part I think most owners will since a good portion of us come from cars that get mileage the Trax easily surpasses, with me that's the case.I am concerned about fuel economy, but I'm happy with what I've been getting according to the DIC. The curiosity comes from my Dad questioning if the information from the car is correct.
consider this: the tank was not real full last time, maybe a quart or two down... that would make the difference.My dad asked me a few weeks ago how I knew the DIC mpg was correct and I thought that was a very good question. Yesterday I filled up and according to the Trax, my mpg for that tank of gas was 30. I wrote down my miles driven for that tank -- 335 and the gallons -- 11.865 and came up with 28 mpg.
I reset all my number every time I fill up.
Has anyone else checked their numbers?
US MPG is about 20% of Imperial MPG.I too wondered about the dashboard MPG indicator. I have run about 5 tanks of gas using the traditional measurement technique applied consistently using the same pump at the same gas station and have found the MPG indicator to read optimistically by about 1-2 MPG. As long as it is consistently off by a known amount then one can reckon the correct/actual MPG using the DIC.

Makes sense. ThanksI think what happened is the smaller tires make more revs per mile, looking like you went further than you actually did.
