Removing your gas cap as little as possible will save you gas. Over 147 million gallons of gas evaporate from tanks each year. I know plenty of people who will not let their gas gauge go below three-fourths of a tank. They tell me that it’s good for the car. It’s not. It wastes gas.
Every time you open the gas tank, you lose gas vapor that your car could use. So you should try to open it up as little as possible. Furthermore, a car that is low on gas weighs less, and it takes less gas to move it. There is no harm in running low on gas. There is only harm in running out of gas.
The trick is to wait till your tank is empty and fill it up. Don’t put the bare minimum in the tank. I know gas is expensive in these uncertain times, but try and fill your tank completely each time you go to the pump.
The more trips to the gas station, the more gas you’ll be using. Fill up your tank, and you’ll save gas and reduce emissions overall.
