Thread: Patrol 4.2tdi fuel usage.

If you went to Repco or Nissan and grabbed a new set of bushes all around and did the engine, body mounts, and steering and suspension dampers you'd get a phenomenal improvement in noise/vibration/harshness intruding into the cabin and also with tracking and ride on the road. Giving the thing a mechanical tart up and checking out injector flow and injection pump settings along with air filters is the other part. When I did mine I got something like 3/4L reduction in fuel useage per 100 just from that work - controlling everything so it's not hopping all over the road makes a surprising difference apparently.

They are not the best geared units (the engine trans and cases come out of Nissan's light truck parts line) and as mentioned have the aerodynamics of a cinder block which helps - not. I was getting around the 11/100 when I upgraded mine to a D22, that was more comfortable and quieter but not much better in terms of economy. In comparison the Ranger PXII is returning 8.1L/100Km, doing it quicker, quieter and more comfortably and actually does something when the right boot goes down.
