Fuel efficiency of Pathfinder?

Remember that the fuel consumption figure quoted by Nissan is derived from a laboratory test, not real-life running. It’s meant to give you a guide so you can compare it to other makes and models. Even so I would expect your car to get close to the consumption in the real world that you and I live in. I would think you should be able to get between 10 and 10.5L/100 km, not 13. Go back to the dealer and ask them to have your car investigated by Nissan to find out why it’s not delivering reasonable fuel economy. If they refuse go direct to Nissan and make the same request.
