This may be a stupid question, but is the cruising range a "learning system?" I have noticed that when I push the limits of the tank (I always chicken out and only end up using 14.3 gallons) but when I do slightly push the limits and drive past the zero cruising range, it will register more cruising miles the next time. Like it "learns" that there is still more of the tank to use?

Second question, what is the most number of gallons you have ever had to put in the vehicle? I have only maxxed at 14.7 so I am obviously not pushing my vehicle to its limits.

Third, what is up with the cruising range suddenly dropping at the end. That's part of what makes me chicken out. Like this morning, I started the car and it said 19 cruising miles. I went two miles down the road and then it dropped to a 0 cruising miles? So I reset my trip B and I've gone 18 miles, I have a 25 mile trip home, do you think I'll make it?
