This resulted in a lower fuel efficiency reading for my first tank than what the car really drove. I still got 33.7 MPG, not bad for a first tank, but it's not true either. I'm halfway through my second tank and have a tank average of 41.5 so far.

My question is: should I count the first tank in the greenhybrid database, or throw it out and call my second tank my first tank?

The questions that keep us up at night...
