There is a certain stereotypical opinion that less fuel is consumed in the warm season than in the winter cold. Alas, but this is not entirely true. Or rather, it is not so.
Summer is the time for holidays and mass movement of people closer to the water. The number of vehicles on the road is increasing, road jams are formed in the settlements and the speed of traffic drops sharply. In this mode, the car absorbs the maximum amount of fuel.
Here, the car rushes on a flat road and it would seem time has come to save. An, no! In hot weather the driver and pulls to rush through with a breeze.
However, as we know, “cruising speed”, when the car spends the fuel most economically, lies within 75-80 km / h. We want to accelerate to 100-110 km / h.
Air conditioning will also increase consumption. But even if you do not include forced cooling, but simply open the windows in the car, you can not wait for the desired coolness, but the fuel consumption will again go uphill. After all, open windows increase the sail.
Also, in the summer, an air filter can be brought up, clogged with dust and gnats, it may not adequately supply the engine with an air mixture, which also will not work in the direction of saving fuel.
