AJW, a tanker load. A standard artic tanker in the UK is 44t gtw, a single compartment heavy oil tank semi trailer weighs 7600kg or there abouts, tractor unit tare weights vary greatly, but most tanker operators go to the lighter end so a tare of around 8400kg is reasonable including liquid pump, giving a total unladen weight of 16000kg, so a payload of 28000kg. Given a specific gravity of crude oil of 865gm/litre, although this varies according to API, this gets us 32700 litres in round figures, which is 201 UK barrels, or 278 US barrels. Incidentally virtually all UK market heavy oil/bitumen tankers are built for 33000l + 1% ullage.
Also worth bearing in mind for those counting tankers, is that they will always be full, a) because it's more cost efficient and b) because under hazardous goods by road rules moving a hazardous tanker at less than 80% full is illegal due to the ullage surge (sloshing about) making the vehicle unstable, this is legally allowed for milk and food stuffs, but not for hazardous.
