Before I start this - I'm aware of the negative consequences of the items I'm about to mention. I was on the interstate the other day in HV mode. I was showing about 25 miles of EV remaining. I read in the manual that when the fuel light comes on, you have approximately 1.1 gallons left. With previous Honda vehicles, this can vary quite a bit, and from car to car. I had a Fit that showed 1.6 left, and I could run over 2.2 gallons and still have gas left. So, curiosity got the best of me. Fuel light turns on. I reset Trip "B" to 0. While paying attention to my MPG (around 42) I figure I should be able to go about 46 miles safely. I was approaching an exit, 46.2 miles on the trip meter since resetting, and warning messages start showing on the dash. The car switched to EV, and I was out of gas. It was about a mile to the next gas station. I FILLED the tank - every drop I could. 8.922 gallons. Several curiosities answered! After filling the tank, and turning the power back on, there were no negative messages. So - I learned that when it says 1.1 gallon left... on mine... I have 1.1 gallon left! Total fuel capacity, of mine, is 8.9 gallons.
