Here's why I don't worry about warming up my car when it's cold

There's a "you're doing it wrong" meme that's showing some strong staying power these days: you don't need to warm up your car when it's cold — in fact, if you do, you could harm your engine.

The engineering behind this revision of what many folks have been told their whole lives is solid, and you can watch this Business Insider video to get the lowdown.

Modern cars don't use carburetors to blend the fuel-air mixture. They use electronic fuel injection, so a pre-drive warmup isn't mechanically necessary.

But here's the thing: If you can't run your modern car for ten minutes or so when it's cold, you should be asking some serious questions about the allegedly advanced state of automaking in the 21st century. It's possible that the old-school warmup would marginally degrade your engine oil, but in 35 years of driving, I've never heard of or experienced this.

Bottom line: Your car should be able to handle some serious extremes of temperature, as long as you aren't spending a lot of time in Death Valley or the Arctic Circle.

Here's why I often warm my car up when it's cold:

  • I want a nice warm car to drive in.
  • I want the seat heaters to be good and hot.
  • I want the steering-wheel heater to be all fired up.
  • I want any snow or ice that's accumulated on the windows to be easy to remove.

The first four are about comfort; the last one is about safety. Plus, I think a warm and comfortable driver is a much safer driver than one who's hunched and shivering and has to wear gloves.

Additionally, you won't waste all that much gas with a warm-up at idle. You'd have to run the engine for an hour to burn a gallon.

So go ahead, warm up your car! It should start to get colder in much of the US over the next few months. Warm away!
