How long does it take to refuel after the tanker has finished unloading the gas station?
Preferably after unloading for a few hours, do not add oil at the bottom of the tank, so that the oil quality is bad, there are scum
Relatively good are the United States, Smith, Rosemont, Japan, Omar and so on. The oil tanker, according to 20t 26m3, the 2600 arrived at the gas station if the seal is still intact, so in order to check it, there are loopholes may play on oil seal,
When unloading, it does not affect the normal refueling
