Lee the owner, driving out a few days ago, did not take long to go out on the road broke down, it can not be started. Rescue teams to the vehicle onto the 4S shop, after the car to conduct a comprehensive inspection, the vehicle is no problem. The reason is later found no oil in the tank. The table shows clearly the oil can be full grid, how it will be out of gas?

By repairman explanation, is turned on when a refueling vehicle, too full of oil plus the oil level sensor card to the uppermost tank, because the sensor does not change in oil level change, so the oil table shows the full grid of. Oil plus too full of hazards far more than that, and I'll talk to you today!

1, causing a fire

Gas station oil stored below the surface, a lower temperature, especially in the hot summer, because of thermal expansion and contraction, if added too full may overflow from the vent. Not to mention wasteful, in case of overflow of gasoline encountered fire (eg cigarette butts), it is prone to fire or explosion.

2, canister damage

The canister is typically mounted between the fuel tank and the engine. Since fuel is a volatile liquid at room temperature are often filled the fuel tank vapor, action of the fuel evaporative emission control system the vapor is introduced into the combustion into the atmosphere and to prevent evaporation. This process plays an important role in the storage means is a charcoal canister. If the fuel is too full, into liquid carbon jar of gasoline instead of gasoline vapor, it would constitute a canister damage.

3, block the air vents

Once the vent hole clogging, it will generate a negative pressure in the tank, resulting in poor oil, not even for oiling. Just after the car situation appears refueling beat the fire engine, or a jump a jump phenomenon at high speeds, it is possible to fill the tank is overfilled due cause.

My advice: Do not add too full when refueling. You can see the volume of the tank marked refueling, no more than the tank's volume label are safe. Usually fuel tank can be simply added to 3/4.
