On average, a car idling for 10 minutes will use about 0.25 gallons of gas. However, in colder climates, a car may need to idle longer to warm up, which can use more gas. Additionally, cars that are less fuel-efficient will use more gas to warm up than cars that are more fuel-efficient.
To conserve gas, it is best to avoid idling your car for extended periods of time. If you need to warm up your car, try to do so for as short a time as possible. You can also reduce the amount of gas your car uses to warm up by keeping your car in good condition and by driving in a fuel-efficient manner.
