There really isn't a set capacity, as the sizes and configuration of these trucks may vary. You could be talking about a single axle straight truck, or a tractor-trailer, whether a regular five axle unit or a Michigan 'sled'. Heating oil weighs ~8.2 lbs. per gallon, and a single axle truck with a 33,000 GVW would probably be able to carry 7 - 8 tons of payload, while a five axle semi truck and tanker trailer grossing at 80,000 lbs. would have between a 20 - 24 ton payload.
A typical delivery truck can hold around 2,000 to 4,000 gallons of heating oil, depending on the size and capacity of the tank.
it can hold anywhere from 750-1000 gallons of water
22 gallons.
200 - 240 gallons.
It all depends on the Truck. Anywhere from 30 gals to 150+ gals on the larger ones for gasoline. The larger Semi delivery trucks can have 400+ gal of diesel. Times that by the $ per gal of diesel which is more then Premium gas here in the states.
