I am debating on whether or not I should throw out the data of my first tank. The thing is, when I picked up the car from the dealership, the very nice lady spent about an hour to an hour and half showing me all the features of the car. I loved it, but as we sat in the car it was hot outside so we had the hybrid system on with A/C. The ICE came on several times during that hour and a half as we sat there not moving. 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...
