Cheering for a car is what you usually do in the car，How to save money is a common topic，There are always many tips on the circle of friends to save money，Are these rumors true? Let me give you a popular science today!

Rumors: Oil and adding too full will cause increased fuel consumption or explosion.

The principle of thermal expansion and contraction, everyone knows that experiments have proved that plastic bottle filled with gasoline will be heated and expanded，fuel tank filled with gasoline，Once the gasoline expansion occurs after heating、Oil leakage of fuel tank，It is easy to fire or even explode after encountering a bright Seabetfire。And，Come on, it is easy to cause the following hazards :? 1. Cover the ventilator，Cause poor fuel，As a result, the car's flameout cannot be started。? 2. The fuel tank is full to increase the burden on the engine，Increase fuel consumption。How much oil should I add? Answer: When the fuel tank is less than 1/4, you need to refuel，Estimated the next mileage in advance，Just refuel according to actual driving needs。

? Rumors 2
Rumors: In the morning and evening, cheer is affordable and loses in the afternoon.

The physical characteristics of the heat expansion and contraction according to the liquid，The lower the temperature，The higher the density of the liquid。Gasoline is charged according to the volume，The higher the density of the same volume，The greater the quality。General morning and evening temperature is lower than during the day，The density of the oil is higher，Therefore, choosing to refuel in theory is the most cost -effective sooner or later。
Experimental proof，The quality of gasoline at the same volume at different temperatures will be slightly different，In the case of low temperature, refueling is more cost -effective。

? Rumors 3
Rumors: Do not refuel when the gas station removes fuel.

A professional water removal device on the gas machines at the regular gas station，The role is to block water and oil。When the oil and water mixture arrives at the waterproof filter，Water absorption fiber and water absorption particles in waterproof filtering Seabetwill absorb water molecules，At the same time, a "protective film" is formed at the same time，Blocking water to penetrate inside。

? Rumors 4
Rumors: It is more cost -effective to refuel at the increase ratio.

The price of gasoline is zero，When refueling "money", it usually goes around，It is possible to lose some "change"; while "liter" will be actively calculated。Taking the 200 yuan 92 gasoline as an example，Calculating the volume calculated by liters should be 26.8817 liters，But when "money" is refueling，The actual refueling volume after entering the four houses is 26.88 liters，There is an error of more than 0.001 liters，Joining less，Press "Money" will lose a lot of money。

? Rumors 5
Rumors: The higher the gasoline label, the better.

real Test knot Fruit :? Wrong Error

Gasoline label is not higher, the better，Even high -end cars are not absolutely equal to high standard oil。The higher the gasoline label，The more anticipated agent adding the more combustion inhibitors，The more flammable substances occupied by，The more difficult it is to burn，and the higher the label，Natural fire characteristics are worse，As a result, it consumes more fuel。

Reminder: It is best to add gasoline。
