Thread: TD6 economy

Having my battery disconnected today i lost my fuel stats but i was on 9.9L/100k for about the last 40 thousand ks which consists of some longer than usual idling.. some towing .. around town and some big interstate trips... i drive pretty easy only sit on 100ks etc but always have half tonne of tools in the back

A bad fuel injector which i am about to replace would have made these figures worse too

Egr deleted, K&N filter, Oh yeah nearly 400 thousand k's on the clock

Some one mentioned about newer petrol cars ecu's providing a richer mixture as a "choke" when the engine is cold... i believe the TD6 does this too as my car pulls very hard all on its own without any extra throttle input but only when it is cold, If i reset a fuel consumption meter it reads very high during this time

And that is what affects economy the most.

she's done nearly 400ks, that's impressive

You're right Dave. The engine adjusts fueling for temps below 80- 82

Yes its all in the foot,

After my next interstate run i should be right on the 400 thousand k mark.. the engine runs sweet except for one injector playing up atm but should have that replaced in a weeks time, Far as i know has never had the head off... i doubt turbo is original, when i get time ill compression test it and pull the head for a look inside and simply to replace the head gasket, I also want to check the oil pressure but have to find where to tap into a sensor etc

Would appear to be a very solid engine.. i think the head will be the weak link with high ks but i could be wrong

In putting well over 200 thousand ks between two TD6 Rangies i have not had many problems, two fuel pumps... one injector it would seem and a steering angle sensor.. oh and a broken ride height sensor if that counts


I really should not have said all that... im sure my gearbox will now explode next week...

How do your measured fill-ups compare to the dash readout?

Back from run to snow last week.
The highway sections, 1300km each showed 9.3l/100km on MFD; actual 9.8 by tank to tank, with average speed 95.6km
All round trip, 3000km with few days crawling up and down and around in snow showed 9.8 on MFD and 10.5 actual.
Appears that this can(easily????) be recalibrated, according to owners manual/rave.
The MFD speed readout is 3kph slow at 100; as tested by gps, but speedo gauge spot-on at all speeds up to 100 kph.
Obviously the plug-in module not making any difference to fuel consumption, but engine definitely more "responsive"/power when required, especially when heavy towing.

I only paid A$110 for this (as quoted 420Nm) module, on clearance sale, so it can stay for a while; priced a 480 Nm remap at $850
Engine at 245,000km; uses between 1/4 and 1/2 litre between 10,000km oil changes.

Oh, and engine started within 2 seconds in -6 degrees without glowplugs every day there; car covered in snow!
Glow plug relay faulty; since been replaced.

Don, you can get a Bluefin remap (505nm) for about $600 when they run their specials. They guarantee to improve fuel consumption. I found it getting better mileage on the highway, but worse around town.

Also wind makes a big difference. We traveled 200km into 20-25kn wind, back opposite direction that afternoon. Same load, road and temp - full 1L/100 difference between head and tail wind.

How heavy were you?

Hi Harlie,
I've noticed the difference wind makes on my weekly 200km runs out to work; yes, at least 1l/100km difference!
On trip to snow; 3 people and full luggage.
I still believe that adding the SS/rubber bullbar, side steps and 3 roof bars have caused a minor increase in consumption to when I first bought the car.
I've now screwed this box to full economy side so will see if any difference. It still seems to perform better than prior!
