Magazine “Behind the wheel” listed situations where it is necessary to warm up the car engine for a longer time in winter.
First of all, if the parking lot is not cleaned, it takes longer to warm up the car. Takeoff will require more output from the power unit, so it must be warmed up longer than usual.
Secondly, it is necessary to take into account the route you will travel. If the car is immediately stuck in traffic jams, the engine will warm up perfectly, and if we are talking about driving on the highway, increasing the warm-up time will be a completely correct decision.
Thirdly, we must not forget what type of gearbox the car is equipped with. Automatic transmission can be warmed up by changing modes, while manual transmission warms up simultaneously with the engine. In this case, you can warm up the vehicle at idle for a little longer.
Fourth, if your car has been sitting in the cold all night and the ice won’t clear from the windows, you’ll need to warm up your car longer than usual. You need to wait until cold air comes out of the stove and the glass melts.
