Why in the summer car owners are forced to constantly and greatly overpay for gasoline

In fact, the summer season is really hot for gasoline dealers who, thanks to the weather, get additional profit from sales. Don't believe? Judge for yourself.

It is known that the same volume, for example, AI-95 gasoline at +30ºС is about 10% lighter than the same volume of the same gasoline at −30ºС. That is, roughly speaking, the warmer, the fewer molecules we actually fill in the tank of the car, acquiring our standard liters of fuel at gas stations.

After all, traditionally, fuel is traded in liters, not in kilograms. If we were buying gasoline by weight, this ambiguity would not exist. And since it is, we have to deal with the following situation. In a 30-degree heat, the oil companies actually sell us gasoline with an additional 10% markup.

Or a 10 percent underfill - this is from which side to look at the problem. After all, the fuel system of a car at any temperature operates not with weight, but with volumes: the fuel pump maintains a certain pressure in the system, and the “brains” of the motor dose its injection, changing the opening time of the nozzle valves. Everything is simple.

Only miracles do not happen: if physically fewer fuel molecules enter the cylinders at each intake stroke, then less energy is obtained from their combustion. The driver feels this effect in the form of a drop in engine power.

To get the missing, he presses harder on the gas pedal, forcing the electronics to increase the amount of fuel injected. At the same time, of course, consumption increases significantly. Not particularly noticeable to the car owner. He, as a rule, does not pay much attention to the fact that he has to stop at the gas station a little more often.

But the owners of gas stations perfectly cut through this moment. Have you ever wondered why every year oil lobbyists and government officials tell us about the spring-summer increase in demand for fuel, referring not only to diesel, which runs agricultural, and in general, all heavy equipment, but also gasoline for cars, obviously taking no part in the annual "battle for the harvest"?

Demand is really growing. Only additional oil to satisfy it, in fact, does not need to be extracted. It is enough just to refuel cars not “by liters”, but “by weight” of fuel and seasonal surges in demand for fuel for passenger cars will decrease to a statistically insignificant scale. However, "oil market players" do not even think about such a revolution. On the contrary, this topic is being peddled in every possible way, using it as a pretext for the next increase in fuel prices.
