Sorry to ruin your day Big Rig. Picked up my Patrol in Canberra today and headed on up to Sydney. 296.7KM later I had used 44.68L - That equates to 15.0589 L / 100 Km. You recon you are stoked. No A/C, but with roof rack and just nursing it along between 95 and 105 kph all the way in the 110Km limit. No traffic.
