One Full Year of MPG Calculations

[YarisOwnersDad]

Ok, fellow Yaris owners, I will have had my Flint Mica 2009 Yaris Sedan with automatic transmission for one year come Tuesday, April 13th.

I have kept a log book of every single drop of gas that I have put in the car since I bought it. The dealer filled it up for me the day I took delivery, and I have kept track of every fill-up since then. I use Gassavers.org to record my fill-ups, but I have also kept an Excel spreadsheet at home.

My overall average MPG for the first year is 36.73.

Apparently Gassavers drops the earlier tanks and only shows the average for the recent tanks, because it is showing that I am averaging only 33.19 MPG. My mileage dropped off pretty severely during the winter months. The 36.73 is the true average for the whole first year of ownership. The range has been from 29.49 MPG to 43.55 MPG. The average price per gallon that I paid for the period was $2.505.
