Good point, Mike.

Even when "calibrated" you should take the absolute readings of the Scangage with a grain of salt. I recently took a trip from So. Cal. to New Mexico and found that my back-and-forth-to-work calibration was seriously out of wack for a cross-country trip. I finally gave up trying to correct the calibration while on the trip and the accuracy returned after I got back home.

The best reliable way to calculate fuel mileage is at fill-up time. There are too many uncontrollable variables to rely on instantaneous readouts.

I wonder why?

Anyone else have this experience?
