Hey there, i bought my '93 toyota hilux surf 3L turbo, around 2months ago, it started off doing possibly around 10-11L/100km its now doing 14L/100km, just wandering what other peoples trucks are getting for fuel usage???
Seems abit od as it all changed within 1week went from descent to poor, i can do up to 1/2 a tank a day haha, but on average ill do 1/4 tank just driving to and from work each day..... ive tryed slowing down on my throttle doesnt appear to make any difference.

my old mazda ute did 14/100 km 2.6 petrol , the new ute mitzi 2.4 diesel 11.9 /100

My 13bt cruiser (3.4 turbo) is getting 12L/100km with 33s and roof rack on.

In My 94 Surf Automatic 3ltr Turbo diesel 31 inch tyres.

I get around 12.5 ltrs per 100km.

If im getting due for an oil change the consumption gets a little worse.
Also a dirty air cleaner or fuel filter can make a differece too.

Just a though, you didn't take it out in the mud that first week did you and perhaps it's not fully disengaging?

my 1990 3y surf runnin 35s gets 14.5-15.5/100 but as said in above message double check ur disingaging properly aqs ive had it a couple of times where it doesnt and ya notice it couple days later,well i do,most of my trip to work is at 110 dwn the motorway so yeh

Check for extra drag first.
Tyre pressures, wheel bearings, dragging brakes etc. Try to push the truck along the garage floor and see how hard it is.

has it got the EGR system disabled ?
(both egr and butterfly in intake)
