I don't know about the new cars, but on first generation Volts .03 gallons is the smallest unit the car displays - it can't measure .01, .02, or .04 gallons.

On a Gen II when you accept EMM you MUST start driving, after about a mile the ICE will start. And as others have said the entire process takes about 10 minutes and will consume exactly .03 gallons of gas.
