Has anyone got fuel consumption figures for a Toyota Prado T/C Diesel Current Model, pulling about a 17ft full size van. I have done 2trips from Brisbane, one to Darwin & one to Bowen. On both occasions I averaged just over 22 ltrs / 100km & am not impressed. Am I being unfair?

Wow that does seem thirsty, my 04 TD prado averaged 16-17lts when towing my 21ft boat to Somerset and back (guessing the boat weighs close to 2 ton) highway driving

I get 12 lts/100km for city driving consistently

Thanks Boxer, I agree with you. I get 12 to 12.5 around town without a vat & have checked the usual things like wheels are running freely, tyre pressures in the van (run 42lb on tandem axles, hankbrake is off, Tyres & wheel hubs are only just warm after a 200km run at about 85km on highway.
I have written to Toyota about the problem & they sent my a rude reply telling me it must be my bad driving as their dealers would have checked everything when I complained to them about it at Darwin, Bundaberg & Nambour when in for service.

is yours manual or auto?

Mine is Auto
What does the van weigh?
Are the tyres light truck tyres? - if so they recommend 55-60PSI, thats what I run on the boat trailer (tandem also)

I will have to double check my figures as most of the time I tow the boat it is only 100kms max or so - therefore it averages back down to 12lts overall when I fill up once the tank is empty

Thank you for staying with me on this one Boxer.
It is auto (as you probably know, whith the current model, the computer locks up the torque converter when the load remains constant for a certain amount of time, so that should help the situation.
The van weighs 1420kg empty, and 1800 to 1900 kg loaded (depending on where we are going & what we need to take
Yes - light truck tyres (They are running very cool - if under inflated they would warm up), Their side walls are standing up straight. I have driven seni trailers, so understand the inportance of correct inflation. I will try inflating them a bit higher & see what happens.

I normally travel at about 85km/hr, but on very good road on the flat will let it run to 90 - 95km

The book tells me to drive in low high, but ahve tried high high (h1 &h2), without inprovement.

Hi Franno,

Towing 17ft Pop Top all-up 1700kg. Average around 16lt/100km. Worst so far has been 18.5lt/100km driving into strong headwind and holding a speed of 95kmh.

Generally tow at 95kmh, 2003 TD.

Your consumption does seem a little high.

regards
Mike

Boat seems to be 1800kgs - so is very similar to your van franno.

I always tow in 3rd and sometimes shift into D if the going is easy and I'm on the highway - generally stick to 90-100kmh
I am impressed with the Prado it does a good job, although you do always know the trailer is there - accelerating in 2nd and 3rd takes a while, but reversing up our very steep entry with the boat is a breeze for her - I used to think I needed to select low range for the reversing, but thought better of it seeing as low can only be selected once the centre diff is locked in and risks winding up the diff.

Sorry I cant help more than that - how is the air filter??

Air filter good. Changed every 10.000km with a genuine Toyota one. & never been off the blabk stuff.
Thank you for everyones help, Particularly BOXER. I am starting to get the feeling that I have a dud one. Would have been nice to get some back-up from Toyota.
