The usual industry capacity for tanker trucks transporting crude oil is 210 barrels, or little more than 8,800 gallons. Nonetheless, tanker trucks with capacity of 50, 100, and 300 barrels are also rather prevalent. The capacity of the majority of trucks ranges from 5,500 to 11,600 gallons.
Typically, larger tanker trucks are utilised to deliver liquids across vast distances. For instance, they may transport oil from a well or pipeline to a processing plant. Local communities often utilise smaller tanker trucks, ones with a capacity of less than 5,000 gallons. For example, vehicles with a capacity of around 3,000 gallons are frequently used for cleaning and transporting septic tanks.
