In frigid temperatures, it’s a common practice for many drivers to let their cars warm up for a few minutes before hitting the road. Some vehicles even have a preset feature that lets drivers start their cars remotely.

In a blog post on its website, Smart Motors Toyota says letting your car idle in cold temperatures can shorten the life of your engine by stripping away oil from the engine’s pistons and cylinders — two critical components that help your engine run, Stephen Ciatti, Ph.D., principal engineer for battery systems at PACCAR, told Business Insider in 2016.

Firestone and Smart Motors Toyota both say that most cars made before 1980 did need to “warm up” when it was cold out. This is because older model cars had carburetors that regulated the air-fuel mixture within the engine and could not accurately adjust the air-to-fuel ratio in cold weather.
