I bought a black package #6 with 3 miles on it on 7/8. After my first 280 miles the bladder gauge showed half full. I figured I was on my way to 56 mpg!!! However, the gauge RAPIDLY started dropping after that, to a point where I filled up at ~310 with only 2 bladder gauge bars left. The MFD tells me that my MPG was 44.5. I am assuming the tank is around 10-11 gallons. Is the computer's MPG calculation wrong? Did I jump the gun on filling up, and would have got another 140 miles out of that tank?
Thanks for your input.
