Thread: Fuel Consumption : How Low Can You Go?

As mentioned in another thread, the best has been 13 litres per hundred, I don't even want to know what the worst has been... 3.5 EFI Rangie Classic.

I run my tyre pressures at 250kPa front, and 350kPa rear. I've never really had much of a problem running them pressures. I am running Hankook muddies, which are rated very similar to Robert's, with a speed rating of 160km/h.

I find with my fuel consumption, that sitting around 100km/h gives me pretty damn close to 10litres per 100km's. However if I speed up to between 140-150km/h, my fuel consumption sits around 25-28litres per 100km's. That's when it kinda hurts. But the look on the drivers faces of Ford Falcons etc is priceless when they see the old girl hauling past them.


That's in a 93 200tdi BTW.

In the disco I have always averaged around the 10l/100km. When towing and low range this seem to double. I haven't worked it out but it can get costly. Hey it still beats a v8 though.

I did not do the figures but was able to make from Mt Isa to Longreach on one tank in the Disco while pulling a Jayco Hawk camper. We filled it to almost running out when we left and when we got to Longreach filled it to top of neck again, put 98ltrs in (tank rated to 95ltrs) The only reason i did not stop and top up with the jerry can before was it was raining that hard I would have got more water than diesel in the tank.

Last night drove to work 56km's and got there with the reserve light just illuminating as I drove in the driveway. Reserve fuel light according to the manual comes on at 9L. Driving home this morning I realised that I'd left my wallet at home so drove into the servo approx 3 km's from work in opposite direction and raided the coin box. $7.45 diesel was $1.45/L giving me 5.13L
I drove home without the reserve light coming on



59Km's on 5.13L= 11.50km/1L


Do that in a v8 on gas or petrol

I run my tyres between 20-25 PSI, I vary the pressure every 5000km. 315x75x16 Procomp Xterrains

I've only just put the 2nd tankful in the bloody great green thing (I'm Thinking of calling it Princess Fiona but thats a different story) and I acknowledge I,m not the easiest on the right foot but I've got a pleasant surprise.

67l for 690k . Now someone validate my maths plz but thats 10.29k per litre and therfore 9.7 per 100.

This is mixed driving, out on the road no more than 105k max, I short shift 1st and then pick up 2nd and run all of the gears through to no more than 2500 RPM using the boost from 1600 to 2500. If I put my mind to it I probably could cut it even further but I love forced induction so the sound of the little turbine spooling up is irresistable.

I'm going to put on a Snorkle and have a good look at the induction system and exhaust soon too in an attempt to open them up and make it breath a bit easier.

Bloody Hell, thats low.
