Angry Worst personal MPG in almost 3 years

WOW. Filled up this week and got a nasty surprise.

I thought I was in store for about a 65 mpg tank according to the ScanGauge, but the fuel receipt/odometer calcs were substantially worse: 55.9 mpg (US) / 4.2 l/100 km / 67.1 mpg (Imp).

The last time I had fuel economy that bad was nearly 3 years ago.

The SG somehow overestimated distance by 34 miles (of 521.8 actual), and underestimated fuel use by 0.83 gallons (US).

Need to recheck my calibration offsets.
