Wasteful Thinking
December 8, 2019
With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin. Some vehicles offer remote starting that let you do that from the comfort of your home or apartment. But is letting your vehicle idle like that good for it?
Manufacturers say it doesn't harm the vehicle. They say it's because modern vehicles are made differently from those in the past. Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders. The engine gets only the fuel it needs, taking conditions into account.
Older vehicles, on the other hand, used to use carburetors. When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions. Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil.
So yes, you can warm up your newer vehicle for your own personal comfort. But consider how much fuel you are wasting. That is not only throwing away money, it's a waste of natural resources. And it puts more carbon into the atmosphere.
Automakers have to be mindful of what fuel economy their vehicles can achieve. So the flip side of the remote starts they offer is a "stop-start" feature. When you stop your vehicle, even at a stoplight, your vehicle will turn the engine off. When you take your foot off the brake and step on the accelerator, it starts up right away. That feature can save as much as 10 percent of the fuel your vehicle uses.
Your vehicle may not have that start-stop feature, but you can still save fuel by shutting off your engine manually if you are waiting somewhere, like a parking lot or perhaps sitting outside your child's school waiting to pick him or her up. It saves you money and contributes to a healthier atmosphere for our planet.
