Yep, that's why I have a ScanGauge II. Much more accurate, oftentimes jibing exactly with the pump or 1 to 2 tenths of a gallon off.

On our Honda, enough people complained for long enough where Honda reprogrammed the MPG computer to be more accurate. It's typically within a half of a MPG of actual fuel economy now instead of 10% high like it used to be.
What year? Cause Honda also got their peepee slapped for an over reading odometer.

But to the topic I would never really put touch faith into the MPG calculations when a known miles traveled / gallons used is usually dead on :)
