Fuel Saving Tips
Topping up means you'll be carrying more weight when you fill up completely. In my car's case a full tank of gas weighs about 94.5 pounds (6.3 pounds X 15 gallons). So if I top up instead of filling up halfway, I'm carrying about 47 pounds more fuel. But if I don't top up, I don't know of any other way to accurately track my gas mileage and if I don't track it, I'm probably going to suffer from the old "out of sight, out of mind" condition and my gas mileage will likely drop at least a few miles per gallon. Frugality as a way of life can prevent one from slipping into wasteful consumption of resources.
