Why Warming Your Car in Winter is Burning a Hole in Your Pocket
17 August 2008

Winter is a difficult time for drivers. It does it's best to wreak havoc on your gas mileage. You may be playing the part of an unwitting ally to winter's effect on your fuel economy. Improperly warming your car up could be burning a hole in your pocket.

Drivers are in the habit of warming their vehicle up in winter temperatures. Drivers seem to be under the mistaken idea that they need to warm up their car for it to operate properly. By warming up they mean idling the car for a considerable amount of time before driving. This misnomer is costing you money.

Many drivers idle their car for 5 to 10 minutes in the winter to let their cars warm up. You should not let your car idle for more than 30 seconds. You need no more than 30 seconds of idling to circulate the engine oil before you can drive away on cold days

When you idle your car to warm it up you are burning gas but not going anywhere. When you let that happen you are getting zero miles per gallon. You may think that idling your car for few minutes or so is no big deal, think again.

To get an idea about how much fuel you are burning by letting your car idle for 5 to 10 minutes when you start it consider this. Assume you idle on the short side, only 5 minutes when you start your car in the morning. Most likely you idle for 5 minutes again, when you start your car again to drive home.

Therefore your car is idling for a minimum of 10 minutes a day. For illustrative purposes we consider winter to be four months long, or 120 days long. If a car is idling for 10 minutes a day for 120 days then it is idling for 1200 minutes during the winter period.

1200 Minutes is 20 hours. Think about it, warming your car for only 5 minutes per start amounts to your car idling and burning gas going nowhere, for 20 hours. Can you visualize your car sitting and idling for 20 hours? Of course not. Then why warm it up for the equivalent of 20 hours of burning gas when it is completely unnecessary?

Warm your car up by driving it. To operate efficiently your car needs to warm up other parts in addition to the engine. Tires, transmission, wheel bearings and other moving parts also need to warm up. Your car's catalytic converter doesn't function at its peak until it reaches between 400C and 800C. The only way these other parts warm up is by driving. The reality is, to warm your car up completely you have to drive it anyway.

To save gas and increase gas mileage in the winter one of the simplest things you can do is warm your car by driving it, not by idling. Not only will it save you gas and money but you will also be doing something positive for the environment. That warm car will stop burning a hole in your pocket.
