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 🙂
In: 9
A few reasons:
-Air density, winter air averages about 10% denser than summer air, so more fuel goes in with it.
-Winters on average have stronger winds, meaning more aerodynamic drag.
-Colder parts in the powertrain makes more friction, meaning some additional loss of power efficiency.
