Hi All, I have been wondering if its possible, so thought I might get some joy asking here. I have an 06 D4D Hilux 2wd double cab, and a work colleague has the 4wd version. Now my ute sits on 2750ish revs doing 110kms where his sits on about 2000. Over long distance this is bound to make a difference in fuel consumption, and was wondering what is different (diff ratio??) and what I need to do to get
mine doing these revs on the open road. Would definately make is quiter too which would be a plus. Look forward to your replys. Thanks

bigfut,
Tyre size would make a difference.
The 4WD ute would have a bigger tyre and therefore require less revs to maintain the same speed.

Hi bigfut. 750 rpm sounds like a big difference between the two vehicles. Are they both manuals? If so are they both in 5th gear. If so I really can't figure why yours would be the lower geared. Bob

I'd say his mates at 2000 rpm is an auto with torque convertor lock up in top gear..apply a load and it immediately unlocks/raises the gearing to around the 2500+ rpm.... or we have an oversze tyre issue

They are both manuals in 5th gear,
mine is running standard size
wheels, so his might have larger than standard
wheels. Can anyone else with this type of hilux comment on what rpm their ute does for comparison?

Bigfut,
Have you checked the Owners handbook to check if the gearbox and diff ratios are the same in both vehicles.
It is also common for the 4wd to run 16" or bigger rims and the 2wd to run 14"or 15" rims. Even with the same g/box and diff ratios this will make a considerable difference to revs at the same speed.
It maybe possible to fit 16" rims to the 2wd but it will affect brakes and acceleration with the bigger rims and tyres fitted.
Disco.
