Wentworth's complete fueling history
It was a low tank, with the MFD reading around 63 of 64 mpg, but I was really surprised by the very low calculated result of 58 mpg for the tank, which I haven't seen in regular (i.e. not a roadtrip) driving since last February in the freezing weather. This was a tank of 60°F weather!
But...it wasn't altogether accurate, as the bladder somehow filled A LOT, and then some, with some fuel spilling out at the end. We'll stick with the official numbers anyway, good motivator to do better next tank!
