that sounds like 1km per litre or less, how much fuel does your tank hold?

If your going through 1.5 litres per 1 km you must have a pretty big leak? The chev in my truck uses about 0.25 litres per 1 km on the road :?

Drain the fuel tank, there should be a drain plug in the bottom, if it comes out nastly looking it may need a clean out and refill....., some tanks have a filter in them as well....

There is something very wrong with your vehicle. There might a fuel leak, or your odometer does not give you
the correct distance. I have yet to encounter a vehicle even the big gas guzzler V8's that consume 1.5 liters per kilometer.
There must be a logical answer to your problem. Do another recheck , to find out whats wrong.

Get some of the Moreys fule additive, it will clean your injectors plus add a biocide to the fuel to kill sludge.

mines started doing the same thing think it might be a fault with the fuel gauge or the electric system, can put a full tank in it and 10min of town driving starts trying to tell me i have less than 1/2 a tank left.

This must be talking the piss.... :?

Surely after you have driven 20km and decided to fill your tank and only put 3ish litres until the fuel pump switchs off you'd realise something was up... :roll:

Using it - unlikely
Loosing it - You would notice petrol all over the ground, check for leaks
Buggered Fuel gauge - most likely, as NJV6 hinted at.

A mate thinks his one is using about 12 litres/100km, but we need to confirm that. Half a tank for the 180km ski trip last weekend. My rangie does better than that.

i use 9-9.5 l/100km all the time..think the worst its ever been was about 9.8L/100km. I got about 8.6L/100km by going a constand 80km on the open road. Rugger/Rocky?Fourtrak are very economical usually. They just have a small tank so dont seem as economic. Not too many 4wd will get better..grand vitara diesel, sportage softroader diesel, jimny, terios, maybe korando, and a few diesel softroader. Rocky, Jimny and Vitara are the most economic real offroader. Some of the utes arent too bad..actyon and rodeo best.

hes talking about the petrol feroza/rocky that runs the 1600 motor. and if your only getting that for the diesel id be having a bit of a look at it. ill get 400-450 depending on where im going and how im having to drive to get there thats in a fez though

the official fuel consumption for a diesel Rocky / Foutrak is 25-35MPG..combined 30 MPG (thats about 9-9.5L/100km)

so if i getting 8.5 L/100km i think im getting a pretty good deal! Only thing i dont like is only being able to get 48L max when its supposed to be a 60L tank..my old rugger was the same.

think official fuel consumption for Feroza/Sportrak is 9L/100kms combined.

I am still a bit confused as to whether you are talking about the petrol Rocky or the deisel Rocky.

If it is the 1600 petrol, change the oxygen sensor on the exhaust manifold. They dont last forever and your computer is getting the wrong (or no) feedback and stuffing up the mixture. See warfs.org under parts for Bosch or other replacement equivalent.

You can also read the engine fault diagnostic plug yourself by following the instructions in warfs.org

I use mine mostly around town and get 11 l/100km and 9 l/100km on open road trips.
