#163 - Get My Engine Running

Not Warming Up the Car on Cold Mornings

It's chilly here folks. I know I've turned into a giant, southern candy-ass in the past three years because this 30 degree shit is starting to feel really freakin' COLD!

Now when I lived up in New York, our house was situated about 15 miles due east of Lake Ontario. This put our home smack dab in the middle of the snow belt, where it wasn't unusual to wake up and find three feet of snow had fallen. And we had no garage. And it was bitter, bitter, bitter cold. So warming up the car in winter wasn't a luxury, it was a necessity. You could have an ice pick and flame thrower and it would still take you hours to clear your windshield without the help of the defroster.

But down here? in sunny Virginia? Where it doesn't snow, or sleet, or ice? Warming up the car just keeps your butt from going numb. And so I won't do it anymore.

Now before you old hardcore '69 El Camino restoration freaks drop me a line and tell me how I'm ruining the engine, you should read this article from my two favorite mechanics, Tom and Ray Magliozzi of Car Talk:


With the cold New England winter weather about to swoop down on us, I have a queasy feeling in the pit of my stomach. Why, you ask? Because every winter when my boyfriend and I get into my car, I start it, then I put the car in gear after about 30 seconds and drive off. This drives my boyfriend nuts, and I have to hear about "how bad it is for my car" to put it into Drive before it warms up. He will start his car and sit there for a good five to 10 minutes before he shifts into Drive. My question is this: Am I really doing harm to my car by not letting the engine run for 10 minutes? If not, how can I prove this to him? I found an article in The New York Times a couple of years ago that stated that nothing is gained by sitting in a freezing-cold car while the motor is running before you shift into Drive. He thinks that the reporter at the Times didn't know what he was talking about. But he just might listen to you if you say it's OK. Please help! It's cold here in Boston! -- Lisa


RAY: How do you prove it to him, Lisa? Hand him this column and ask him to read the following aloud:

TOM: Dear Lisa's Boyfriend: You have your head so far up your tailpipe on this one, it may be coming out your air intake.

RAY: How's that, Lisa? Will that do it? You're absolutely right, as is the reporter from The New York Times. On modern, fuel-injected cars -- basically anything made in the past 20 years -- you're not helping the car at all by warming it up for five or 10 minutes.

TOM: On older, carbureted cars, that kind of extended warm-up can actually cause damage to the engine by diluting the oil with excess fuel. So it's even worse if you have a really old heap.

RAY: But with modern cars, all you're doing with a long warm-up is wasting gas, increasing pollution, raising the temperature of the planet and making yourself 10 minutes late for your chiropractic appointment. The proper procedure is to start the car. If it starts and keeps running, put it in Drive and go. Go gently (don't back out of your driveway and floor it right onto a highway entrance ramp), because you'll be warming it up during your first few minutes of driving, but DO drive it.

TOM: If it's bitterly cold out, like 10 or 20 degrees Fahrenheit or lower, you can let it warm up for a minute or two to allow the oil to thin out a bit and circulate completely. But other than that, if it runs, driving it gently is the best way to warm it up.

RAY: So tell your boyfriend he not only needs to get off your case about this, but he needs to stop warming up the car himself.

TOM: AND, to make up for all the misplaced grief he's given you over the years, he needs to start going to bed 10 minutes before you do, to warm up the bed for you on cold winter nights. That's a warm-up activity he can do that's actually useful!


So there. It's good for the environment and not damaging to my car. Now if I can only figure out how to thaw out my butt, I'll be fine.


Savings:

Warming up the car -- what is that -- like a ten minute run? And we've got about 30 days of really cold weather down here. So that's a total of 300 minutes of needless gas consumption. By curbing the urge to heat up, I'll save 3.75 gallons of gas this winter. Now if I could get all the other Virginians to join me, that would be 28.5 MILLION gallons of gas saved. Now that should get your motor running!, er, I mean, not running.



Difficulty Level: 1 out of 5

It's not difficult to do, just a bit chilly. I guess I'll just need to bundle up and wear gloves until it warms up again.

Heh, I loves me the Car Talk guys.

You could make yourself one of those rice heating pads and microwave it for a couple mins, then sit on it. :D

We lurve Click and Clack the Tappet Brothers at our house.
Sometimes we just laugh because they are laughing. What great, informative radio. And they know EVERYTHING about cars.

I don't miss those central NY winters one bit. I have also become a candy-ass southern. I have lived in NC for 3 1/2 years and it was 30 degree yesterday and it SUCKED!
