76 series landcruiser gxl fuel consumption

"a tank" is like a piece of string-without knowing the size of it you probably wont get much sense.
However if it goes from 550/600 a tank to 480 when you more than double the total load Id say that was absolutely outstanding?.
Bit odd though that you get better city milage than highway though?

Note your km, or zero your trip meter, when you fill up your fuel tank.

Drive where you want to drive.

Fill your fuel tank and note the distance you have travelled from the previous fill.

Then work out how many litres you have used for how many kilometres.

Pulling a three tonne boat at 110 kmh seems like a pretty good way to use a lot of fuel.
Driving at 90 kmh in fifth at a steady speed seems like a pretty good way of not using very much fuel.

High revs will kill fuel consumption in a diesel. If you feel the engine is revving too high, then the ability to control this is with your right foot - slow down, or change up a gear.

These are things I have learnt in my many journeys, I hope they are useful to you.

Sounds about right, in that if you are interested in saving fuel, you are driving way to fast in such terrain with that load. As for the consumption rate; much better to use the odometer between fills, while recording litres at the pump - the observed 'full and empty' status of tanks varies too much.

We drive a dinosaur compared to your 76. Ours is a 2000 model 100 series and we tow 3.5 tonnes of caravan. Towing, our consumption is about 20L/100K. but we tow at about 85 kph in 4th. Revs at this speed/gear are about 2400 rpm.

I am not surprised you are gulping fuel towing 3 tonnes at 110 kph. Slowing down or towing less are your only realistic options.

Welcome to the least advertised downside of the new V8 Tojos. The fuel consumption can be shocking. If you drive the vehicle as stock standard and do not exceed 2000 RPM at any stage (this means sitting about 85-90 kph highway cycle), then you may achieve figures close to the 10/100 Toyota advertise. Any variance and you will loose km per litre instantly.

Tyres, bull bar, roof-rack and extra vehicle weight will negatively effect fuel economy immediately. So will driving it up-hill, over 90 kph or towing anything. My beast is extremely heavy, has large tyres and I tow just over a tonne with trailer and quad. When packed and travelling on holiday, I calculate my highway km at about 5km per litre (20/100). I’ve had as good as 7km per litre but normal highway average is more like 6 to 6.25 km per litre.

Towing a 3.5 tonne trailer at those speeds, I’m surprised you did that well actually. You could try replacing the standard snorkel head with a scoop type. A 3” exhaust may also increase your fuel efficiency but overall the only thing that will help is driving it like your great aunt in her Barina on her way to church…..slooowwwlly.

Hi Daniel
I get to smile at these sort of posts and the replies.
I have a 2007 model with a canopy ... as said before 'as aerodynamic as a besser block"
I have two 90 litre tanks and when the red light comes on I zero the odo run it for another 55kms and switch to the sub tank.
Lift your right foot Danny !
98 kph is the go anything after that sucks the fuel.
IE. Longreach to St.George 810kms. = 121lts
I tow a 1200kg camper with the canopy loaded with water recovery gear tools etc.
I'm an old fart.

Driving to Eden at those speeds you must have been on the Hume and then across to Brown Mountain.

I would be sceptical of anyone achieving those speeds on the coast road.

All 4WD towing sucks fuel. To get better consumption, you have to drop the revs (speed).

G'day Daniel,

if you work on 70 litres used for 480 km, that equates to about 14.5 litres per 100 km.

Towing a 3 tonne boat with a fourby, in that terrain (it's definitely not a dead flat road), at 100 -110 kph is pretty good.

I'd be more than happy to do that.
If you want to use less fuel, drive slower. It's the right foot that controls how much fuel squirts into the engine to make it go faster.

Have fun,
Steve

G'day Daniel
As mentioned quite often the higher speed uses more fuel.
It is running inefficiently and the extra speed just increases the rate and degree the inefficiency is happening at.

Most people do not run their vehicles at the optimum.

When your engine revs are high enough to make maximum torque then that is around the revs you will have to travel at for economy.
5th gear may not be an option if towing large weights and one poster has mentioned they tow 3.5 at 90km/h in 4th and this is around 2400rpm.
Since their engine probably makes max torque at 1750rpm they are also running well past the optimum fuel economy position and if in 4th then 80km/h will do far better again because the torque is there but not the rate of fuel usage.

Yes it is slow, but the balance of mass moved for fuel used is what people are hoping to achieve.
Everything nowadays is GO GO GO and 80km/h a few years ago was normal and would have received respect on the road, for what you are towing.
Fuel economy! Who gives a Rats Armpit about that.
All fuel tests on vehicles and economy runs are based on what is unobtainable in the real world.

If a similar engine was used to power ie, a generator, and it was working as hard as a tow vehicle engine, the generator would be set to continuously run at the optimum and be achieving far better relative fuel economy than tow vehicles. Our situation of varying conditions means it is harder to achieve.
The people who get good relative fuel economy are the ones who understand the limitations and abilities and act accordingly.
Screaming down the highway isn't applying anything except the right foot.

Hi Daniel
I have a 76 series, tank distance hard to tell, mine has 130lt tank,
but best way to get good consumption figures is get a Scan Gauge,
it will tell you instant usage and you can learn what is the best at that time
Consumption will vary with ambient temp, headwind, ect, scan gauge will tell you

But your figures aren't bad

say 80lts.....480 km = 16.7 lt per 100k .. towing
575 km= 13 lph................. hi way
750 km = 10.5 lph.............. city (start in 2nd do we ?)

From that a bit quick on the hiway, but she is a work horse not a sports car

But I do agree another gear would be good

Cheers Ken

Diesels ,as long as I have been driving them,have always been frugal when used in 'track like' driving.Once you drive them at highway speeds they tent to used fuel like a petrol car.That's my experience.......

G, day Daniel
I ha ve a 2008 troopy with 3 inch exhaust and safari snorkel and 285 x 16 tyres It weighs 3.2 tonnes loaded. If I sit on 100 kph I get 650 to 700 kms on 85 litres. If I sit on 110 kph I get 600 to 640 ks for 85 litres.. I also think it could do with an extra gear or an auto gearbox would be much better as there is no shortage of power. Fyi it chews the diesel up when sitting on 140 kph on the NT ROADS.
