Here is a link to a web site that lets you easily convert between gasoline gallons and kilowatt hours of electricity.

If you just punch in how many kilowatt hours you used to charge your electric vehicle, it will tell you how much of a gallon of gasoline it equals.
Enter this number into the Ecomodder garage fuel log, along with how far you drove. (You reset the trip odometer every time, right?)
Then you can use the Ecomodder Garage Fuel Log the same way everyone else does, except you will realize how efficient electric vehicles are!
PS: Yes, the the garage fuel log DOES allow you to enter very small parts of a gallon of gas. My last charge was equal to .0202 gallons of gasoline, and the garage lets me enter that correctly!
