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.

Project MPGiata! Mods for getting 50+ MPG from a 1990 Miata
Honda mods: Ecomodding my $800 Honda Fit 5-speed beater
Mitsu mods: 70 MPG in my ecomodded, dirt cheap, 3-cylinder Mirage.
