I just got 37.91mpg, over 196.3 miles, and 5.18 gallons
. This tank is a commuting tank, and this is the best I have ever got for a pure commuting tank!. My next tank won't be so good - started well, but I started the car about 40 times trying to test SuperMID with my Oscilloscope
The fuel gauge dropped significantly (I managed to warm the engine up to the point where the cooling fans came on, twice, without moving the car at all).
