eli5:Why do cars consume more fuel in cold weather?

348 views

I noticed my car burns more fuel in winter. I don’t use the heater or Air Con. So all being equal why more fuel? Is it something to do with Oxygen density in cold weather? If so, please explain 🙂

It takes longer to get to operating temperature. The coolant temperature sensor tells the computer to make the fuel injectors spray more fuel when the engine is cold.
