I have recently bough an 2004 3.0 l TD Hilux. It is a single cab with an alloy tray. The tyres are what came with the vehicle and they are Bridgstone Desert Duelers - 9R15LT. The only weighty additions are a steel bullbar and a tow bar. I only travel about 100-105 km/h on the open road and I am not a lead foot around town. The best fuel economy I have got is 13l/100km without any load. Is this the best I can expect? My old '86 2.4l Diesel tray top averaged aroung 11l/100 km and that was loaded to the gunnels.

It hasn't had a service since I bought it and I have only done about 2000 Km so far but it does have me a bit worried.

Any comments would be appreciated.

I bought a 2003 3 l non turbo single cab alloy tray early last year. It had 42,000 ks on it and still had the original factory fitted Bridgestones on split rims. On its maiden voyage, and carrying only my wife and I plus an Esky and a few suitcases on the back, we did 600 ks that included passing through Sydney and it did 10.22 l/100 ks. The speed was mostly between 95 and 100.

I would expect a turbo to do better.

A member of my club has a late turbo and claims to get 10.5 fully loaded.

I would be happy to get 10.5l/100km. There was only me, a swag and an esky on my trip which was about 1600 km. It was mostly country driving and it was a bit windy and I went through the Adelaide Hills once but I still expected better. My Hilux has done 106000 Km but I don't consider that a lot. It isn't due for a service for another 2000 km but I might take it in early.

Take it to a Dyno specialist ans for approx $150 for the test, you can see what is going wrong.
Maybe something simple, like a clugged up air cleaner, a sensor, or maybe the chip may need to be tricked up !
At least you will get a starting point !

Good point. I just checked the Yellow Pages and we actually have a Dynotuner in town. I didn't think we did. I will have a chat to him and see what can be done.

I had the same drama with my 2005 Prado. Best I could get was 13.98 litres per 100. Toyota said nothing wrong.
I fixed it. Sold it.

I just bought the bloody thing. A friend has a 2005 Hilux Dual Cab 3.0 l TD and he delights in telling me that he gets 7.5 l/100km on the highway.

Bob, doesn't sound good enough to me, but being the 'old' 3.0 it is probably going to use a bit more fuel than the new D4D. I have an '05 TD (new model). Before adding heavy accessories, I got 9.5 to 10 lt per 100km. Once I added bull bar, dual batteries, canopy, drawer unit, etc etc is declined to 11.5. On trips with CT behind, boat on top, and chock a block with 'stuff' I get about 13.5 lt per 100 km.

So even allowing for the different engine, I think you should be doing a bit better than that.

But I tend to cruise at 90 to 100 and generally not over 95 when towing. That probably makes a difference. My worst ever economy was when we 'pushed it' on a leg of a big trip while towing. Cruised at around 105, sometimes a touch more and it used about 1.5 lt per 100 more than normal. Used 14.5 compared to 13 for the whole trip. You might have to reduce the weight on the pedal to get better economy if that's what you are after.

Thanks for the reply. I find the Hilux is easier to drive at about 100km/h and I rarely go over it but if I am making a quick trip to see one of my kids, or going to the footy I don't want to drive at 90 Km/h. On my holidays up north I hardly get over 80 Km/h and even with the extra load my fuel consumption is ok. (It did on my old Hilux).

I wonder how much difference tyre pressure makes? I have adjusted them using the 4 psi method that has been recommended by many on this forum. Initially they were set to about 45 psi but the ride was pretty hard so I dropped them down to 30 psi. After checking them about 150 Km later I had to pump them up to 35 psi. Does this seem the right thing to do or should I pump them up a bit more?

I was pretty happy with the old Hilux (except for having to put it in L4 to be able to climb out of a creek bank camp, and having bits fall off just when you didn't really want them to, and never being able to pass anyone etc.) and I must admit I haven't really worried about things connected to fuel consumption. I just got it serviced avery 5000 Km and had bits put back on when required.

I just find it a bit wierd that a 22 year old does a little better than a 4 year old.

Thanks for you reply,

p.s. I love this forum. I have learnt so much from it.

Bob, when you get to WA, you should know you are expected to drive with-in 10 Kph of the posted speed limits here, it's written in our "driver licensing handbook" and the highway limits are 110 and 100 Kph.
It saves 'convoy's with 'tourists' in their overloaded vans holding back 53 Metre long trucks on the roads who like to sit at their max speed limit.
In the East the trucks are only about 35 Metre long.

Looks like Davoe is right Mainey.
WA Minimum Speed

Minimum speed of 20KM under limit on freeways. That is all.

Must admit I had not heard of this before.

Mainey and others,
Luckily I now have a TD. With my old bus I would have been fined everytime I drove on the freeway especially if there were hills. I would have been fined for going over the speed limit down the hills and fined for doing under the speed limit going up the hills.

Hi Bob.
My Hilux is tha 2005 model turbo and if you look at the photos on my rig you will see how it is set up.The canopy adds some wind resistance plus 150 litres of fuel and 50 litres of water plus all the extras and a lift kit all add up i suppose.If i drive at 100 klms an hour i get 12.5 klms to 100 litres but if i start pushing her it goes up. On a trip home from the S bend against the wind i got up to 15 litres per 100 klms.Funny thing is sand or slow driving such as the holland track does not make any difference i think in my case its all wind resistance and above 100klms an hour and into the wind makes fuel use increase.A mate of mine has a 3 year old Navara and gets 9 to 10 litres per 100 no matter how he drives and has kept a log book from new.My air filter is a unifilter with the pre filter but i have done the stats with the standard filter and it comes out the same much cheaper to maintain though.

Cheers Graeme

Thanks for the reply graeme W. Your fuel consumption seems about right to me but my Hilux has nothing like the gear you have. I will see what my mechanic thinks. I am going to see him tomorrow.

Nice setup on your Hilux. You have a lot of gear under the tray and/or out of the canopy. I like the idea of the drawer system. I am going to install a similar type of setup myself. I intend to sleep in my canopy so I need all the space I can get.

Hi Bob.

We sleep in our canopy and its a bit tight with the fridge and 125 litre ice box but for short stays on the beach or river its fine.For extended stays we take the our oz tent.Ended up puting carpet on the roof to help with condensation and we have a wheel step for easy entry to the tray.Most of our time is fishing on the south coast or marron in season and the setup is good for that.

Cheers Graeme.
