It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air. When gasoline burns, the carbon and hydrogen separate.
(I can't speak for other parts of the world.) A gallon of gasoline weighs about 7 lbs, and the truck weighs quite a bit itself, so you don't see liquid hydrocarbon tanks exceed 10,000 gallons. That would push it into DOT permit load territory which is substantially more paperwork and possibly a mandatory police escort.
