My surf is a non intercooled 1kz-te like yours, weight probally about the same if not a little heavier. Consumption is about right IMO, maybe a little on the heavy side. You could probally help it by pumping your tyres up. Your running 31's right? The other guys quoting lesser figures was only running 9R's...
I'm getting about 12-14 around town depending on what we are doing. Tyre's are 31" MTRs @ 42psi all round. We are also running an Auto which does chew a lot more juice around town as there is no engine braking (one of the bigger fuel savers with diesels as they don't drink while there is no throttle).
My question to you would be: Do you have a snorkel
If you do, take the air ram off and check for a big metal washer/restrictor (this has been mentioned on previous posts). Mine had one, apparantly it is only supposed to be installed on petrol versions however it is obvious that the guys at Opposite lock (who installed my safari) did not care to read the instructions and put it in anyway...
This thing was causing havok on my bus, overheating, blowing smoke and poor fuel economy.
If it's there, RIP IT OUT!
But poor fuel economy on turbo diesels is often air intake related. Check your air intake system, if you can make it more efficiant by removing those stupid plastic bits that wind along the body up to behind the headlight, do it. MAKE SURE YOU AIR FILTER IS CLEAN!!

Thanks for your response. I am running 9R's at 38 psi.The vehicle is fitted with a Safari snorkel
which was installed before I purchased the vehicle. I will check to see if there is a restriction in the form of a washer.
