On the day of pickup, I found out the fuel gauge was below F when I was leaving the gate. I immediately complained to the staff at the gate, but they said the tank was full. Since it was my first time renting a car, I believed them, thinking there was a problem with the gauge. Driving from Calgary to Banff, a distance of over a hundred kilometers, I had to add 18.452 liters of fuel. From Banff to Jasper, a distance of over three hundred kilometers, I only needed 20.797 liters. Just an additional 2.345 liters could cover 200 kilometers. I only drove a total of 1115 kilometers during the entire trip. Can ZuZuChe provide an explanation?
