Motorists have been warned to stop making a common, and very bad habit, or risk wearing out their engine. In the fresh message, consumer champion experts at Which? urged people to ‘stop’ unless you have one specific type of car. And if you continue, you could end up with a fine.
In their post on X, Michael Passingham, a senior cars researcher, was asked whether people should leave their car running to warm the engine up. His answer? “No. Only cars with carburettors need this to be done, and they haven’t been made for more than 30 years. The only exception to this is if you want a nice, clear windscreen and a toasty interior when you get in. Some new cars have apps that you can turn the car on remotely and have the car ready when you’re ready.”
The expert added why it is never advisable to warm up your car engine by leaving it running whilst you wait inside. It states: “While advice varies from manufacturer to manufacturer, it is normally preferable to drive your car gently immediately after turning it on, rather than leaving it to warm up. Not only will the engine warm up more quickly, reducing the potential for engine wear, but you’ll also use less fuel in the process.”
But what if it is cold outside and your car windscreen is frosty? The experts say that if this happens and “your car is iced over, use an ice scraper or de-icing spray rather than leaving your car running and relying on the heating.” In its blog post, the experts further recommend that people take action early. It reminds people getting behind the wheel: “Ensure your car is regularly maintained according to its service schedule.
