MPG Trip computer vs. my calculation
Has anyone else compared the average MPG the trip computer returns on their Elantras? I have a 2008 EX; for example, during my last few fillups, my calculation is always higher than the trip computers. Last time I calculated 29 vs 27 on the trip computer.

First, be sure to reset the computer every fillup. Second, make sure you fill up the same way every time. It's very easy to fillup more or less and that will throw off your manual calculation. There have been times my trip computer and manual calculation are off by 1 mpg but for the most part they are within 0.2 mpg.

I hear a wide range of info on this issue. Usually when there's a difference, though, the trip computer has the higher number.
In addition to our Car Reliability Survey, TrueDelta also conducts a real-world gas mileage survey that includes questions on driving style and driving conditions, so people can find the responses that fit the driving they do.

A bit of a core dump right now--working on that. It's possible to report results from a manual calculation, trip computer, or both. Haven't performed an analysis to see how large the differences tend to be, but it's possible and I should. Just need more time...

Hyundai Trip Computer
The trip computer in my Santa Fe re-sets the average fuel comsumption file with every fill up. I would like to monitor fuel mileage over a few tank fulls and different driving situations. The manual indicates this average calculation must be reset manually by use of the reset button. Is there some setting I can adjust/correct to prevent the automatic re-set?
