Hi all

when i upgarded from my series 3 3lt GU to the series IV I noticed a difference in fuel consumption. The crd using about 2 lt per 100k more than the older motor. This was backed up by not only difference on the fuel guage but by actual useage figures.

The car has travelled over 50K now and in the last few weeks i have noticed a huge improvement in consumption. It is still not as good as the Series 3 but it is improving all the time.

Has any one else noticed this and if so what mileage did it occur for you?

Alan, head over to, any questions to do with patrols are best answered there, particuarly if you have a 3.0l GU. Id go as far to say that every other site is biased against the 3.0l

This is situation reported by a few CRD owners (some with much worse fuel consumption, more common in autos than manuals though).

CRD is not series IV either, its a series V btw.

Every person I've spoken to who did the "upgrade" complains of more fuel consumption. Plus one person recorded 715 deg C EGT on the flat highway at 100kph on my Cape York Trip in 2008, so there must be plenty of fuel going in to get that temperature.

Hi Alan,

I have a 2004 Series 3 Patrol 3ltr Manual with a 141,000Km on the speedo consistently achieving 1130KM to 1160KM from both tanks and this is with metropolitan driving every day. I also use Valvoline two stroke oil added to my fuel tank before each fill up and this has added slightly to better consumption and the motor very quiet especially at cold start up. Maybe there was an issue with your motor that could have been sorted out?

Cheers Rob
