Free 7 litres of ADBlue Urea diesel emission fluid
7 litres of ADBlue for FREE, however not the 10L fuel can it is in, which is worth $29 from REPCO. You can either take the fluid only for nothing, or buy the tank for $29 with the fluid. The ADBlue was from an Ampol station bowser about a year ago but I didn't end up needing it.
