Are the Nissan Navara's Fuel Efficiency Claims Accurate?

I've been considering purchasing a Nissan Navara, but I'm concerned about the advertised fuel efficiency. Can anyone who owns a Navara tell me if the real-world fuel efficiency matches what the manufacturer claims?

I've had my Navara for 2 years now and I can tell you, the fuel efficiency is definitely not what they claim. I get about 15-20% less mileage than they advertise.

I've been pleased with my Navara's fuel efficiency. I consistently get the advertised mileage and I've owned mine for 5 years.
