What is the difference between truck diesel and normal diesel at fuel stations?

Truck diesel is the same as regular diesel, however there is a very good reason for you to not use these pumps. Most pumps labelled as being for trucks are high-flow, meaning the nozzle is likely to be too wide to fit in your vehicle’s fuel filler neck.

Secondly, as it has been designed to fill high capacity truck tanks, the diesel will come out of the pump much more quickly than a pump designed for light vehicles.

For both reasons we would recommend sticking to the regular pumps for light vehicles.
