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 🙂

Air is more dense, takes more energy to push through. it will have more and more impact as speeds get higher.
Winter tires are softer and more aggressive. Good for traction, bad for fuel economy.
Snow and slush take more energy to push through.
Even spinning your tires at an intersection while trying to get going is taking energy that’s not going into forward momentum.
Edit: Also, when left outside all fluids/oils cool off and become more viscus. It takes more energy to push them around or rotate shafts in them until they warm back up.
