Historical background
The 42-gallon standard became official in 1872, but its roots go deeper. Early oil producers used whiskey barrels (40 gallons) for transport. When railway companies insisted on standardized containers, they added 2 gallons to account for spillage - probably teh smartest business decision in oil history. The "bbl" abbreviation might come from Standard Oil's blue-painted barrels, though some historians dispute this origin story.
