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 🙂

What vehicle do you have? Type of propulsion?
Cold air should help a internal combustion engine, not the opposite.
The only reason I can imagine is: driving on snow or water or mud makes more resistance than dry tarmac.
Second if you have a hybrid car, batteries are heated because they can’t handle cold temperatures. If you have an electric or hybrid car, it will use some power to heat the batteries in winter and that has a negative effect on consumption. This is more marked on short commutes, given batteries are heated in the very first minutes of use.
