Amazingly, I'm going to have my best tank follow one of my worst! We took a 600 mile trip with a trunk mounted bike rack (first time using it). That brought us down to 47. My first sub-50 mpg tank in 52 full tanks!! The current tank is vastly different! I'm currently at 220 miles with 59.5 displayed (should be well over 60, due to the usual error). I'm hoping for my first 60+ tank. Best (prior to this) was 56 a couple of years ago.
