There are two situations in which the oil tank is not filled with enough oil. One is that the oil gun in the gas station does not allow the gun to jump when it is very full. Basically, the gun jumps when it is one liter to one and a half liters short of the mailbox opening, so it cannot be filled to the full. The other is a change in pressure in the gas tank caused by a blockage in the car's activated carbon tank, resulting in a lack of fuel.
What is the reason why the tank is less than full of oil
What's the reason for the lack of fuel in the tank
Is the fuel tank filling up or is it filling up
1, show: the oil drifter is wrong. My old Versa has a problem with the oil pump, but I can't replace it.
2, really dissatisfaction: the carbon tank problem to lead to a problem in the air pressure, leading to a mistake jump in the oil gun.
3, and is you want to add to the mouth, this is not done. You're gonna get a leak. Too full can't leave some air
Can you fill the tank with half gas
It is better to add half of the gas when filling up, so that you can reduce your own weight and save fuel. But then again, general motors at about 50 liters of fuel tank volume, also have part of the tank as a standby, half is about 20 or 30 liters, the appearance of the gas density is around 0.7-0.8, that is to say about SanSiShiJin weight, the role of it for a car to reduce fuel consumption is very low, but if go when we point road, Half a tank won't be enough gas to make a detour.
Therefore, there is not much need to pay attention to when to refuel at ordinary times. It is recommended that you add it before the indicator lights up or when the remaining quarter or so is OK. Instead of caring about these, it is better to see which gas station has good oil products, and pay attention to the recent preferential activities, etc., it is recommended that you fill it up directly at once.
Hazards of a too full tank
Personal feeling is not appropriate to fill up, appropriate to add 80%. The reasons are as follows:
1. Filling up increases vehicle burden and fuel consumption
The effect of this is negligible for most people, as large people generally don't care about this amount of weight, but it should be mentioned anyway. Like I used to like to put things in the trunk, more and more, the result is the fuel consumption......
2. Risk of fire
When the tank is too full, the volume of gasoline expands and can burst the tank. Automakers take into account this, so cars have air holes. When the tank is too full, some of the gas can escape through the air holes. Gasoline is highly volatile, at this time meet an open flame (may be an unextinguished cigarette butt), it will cause a fire.
3. Cause not smooth driving
If the tank is too full, there is a risk that the vent will become clogged, creating negative pressure in the tank. Cause the car oil supply is not good, the car will a channeling channeling. If you can imagine, the picture below. Yi... Yi... Yi...
