I've got 160 on the clock and Im getting just shy of 5km to the litre.
That is running bigger tyres (33"s), roof rack and always loaded though. Mine is a stock petrol with snorkel and finer filter.

I have a 96 diesel 80 series with after market turbo and running 285/75 x 16 tyres.. I only get average 6.5k's per litre (same as before the turbo), been hoping for figures like yours though, just can't get close!

94 Turbo Diesel GXL Manual with 215k on clock.

I get about 13L/100 around town and about 12L/100 on the highway with just usual baggage and 2 persons onboard.

When I am towing my caravan I get about 15.5L/100 and with my campomatic off roader I get about 14L/100.

4WDing ???, who knows, depends on the level of difficulty.

Havent taken the time to conver those figures to KM/Ltr.

Hope this helps

Some folks use a system of km/litre to express fuel consumption, I guess its an old carry over from the mpg days.
It is NOT a good system IMO, the numbers you get are just too small and would require two decimal places to be reasonably accurate.

I much more prefer to use the litres per 100km figures, as in the above post, they give larger numbers for easier comparism. These also reflect the fuel usage better, IMO.

No need to convert anything here, it makes perfectly sense to me, LOL.

Hi V8troopie,
just wondering if the km/lt system is no good then using the lt/100km system how do I figure out how many litres I need to cover a 738km stretch, or how many km's I'm gonna get out of my 75lt tank?

Pezza, is it really soo difficult for you? With your first question, multiply the l/100km figure by 7.5 = (738km rounded up to 7.5x100km), therefore 15x7.5=112.5 litres.
the second question: divide 75 l by the l/100km figure, eg 75/15=5x100km or 500km.
I assumed a 15l/100km economy in both cases.

You would have to do multiplications and divisions with your l/km figures as well and get no advantage there.

Where I see the advantage with the l/100km method is: the smaller the figure the better the car economy. It is also much easier to use this method for the actual testing of the car's economy. Fill her up, drive 100km, top her up and see how much she'd used, done.

You'd have to go through several tank full's to get a reasonable accurate km/l figure since you never know *exaxtly* just how much fuel is in the tank at any time.

The economy figure is the opposite with the l/km method and you'd have to deal with 2 decimal places to get any reasonable accuracy.

Clear as mud?

G'day V8troopie,

Point taken, though I still think my system is easier, 15/100=6.66km/lt
738km divided by 6.66=110.81lt, accurate, no rounding up or down.
Second, multiply 75lt by 6.66=499.5km. simple and accurate.
You say much easier to use your system to measure a car's economy, I wish you luck in finding a servo after EXACTLY 100km of driving, using my system you top it up, drive however far you like to a servo, example 106.5km, then top up again, 106.5km divided by however many ltrs you filled up with=your km/lt.
Please do not take this in an "I know best arguing type tone" my reply is in a fun, light hearted debate. I was genuinely interested in how you use your system to calculate those fugures without first converting it to the km/lt system, now I know, so I have learnt something new for the day.
In the end, the diferences in our final calculations aren't worth losing sleep over, to travel a 738km stretch we both have nearly the same figure, add in a safety margin and neither one of us is going to run out of fuel, you say tomato, I say tomato.

Happy fuel economic traveling.

1997 80s normally aspirated diesel, 216,000 on clock. I keep records in l/100km but will convert

around Sydney - 14.5 = 6.9 km per whatsit
long haul, medium load, no trailer - 13.1 = 7.6
long haul with caravan - 15.0 = 6.7

All plus or minus, and speed dependent

Gee,

Interesting to see that the thread started with Km/Litre and ended up with people quoting Litres/100km which is what most media, magazine articles and dealers have been using for a few years.

I log my usage on a spreadsheet and have worked out formulas that calculate L/100km, km/l and even Miles per Gallon (my dad still talks in mpg!).

One day we might all talk the same language. But until then, the 14 month average for my 120 series Prado turbo diesel is 13.76 l/100km, 7.27km/l or 20.52mpg. Take your pick!.

Yes i know you actually wanted figures for an 80 series but I could not resist a post!

Cheers
Muddy

Hi All,

There was a site mentioned on here once that allowed you to enter your fuel usage and km readings and did all the calculatins for you in any manner you wanted either km's to a litre or or litres to a km or mpg!

Can anyone remember the name of that site?

93 turbo diesel automatic , 8klm per lt round town
11klm per lt h/way unladen
10klm per lt h/way loaded +towing c/trailer
pre metrics = 36klm per gallon =22.5 miles per gallon at worst round town
and 49.5 klm per gallon =30 miles per gallon at best on h/way.

give or take the odd ft/metre/litre/gallon.

Bill, out of my old 94 model 80 series GXL diesel (not turbo) fitted with two rola racks & a loaded carry basket I would regularly get 8km per litre which comes out at around 12.4l/100km
The new 98 model 80 series GXL diesel (not turbo) 40th anniversary edition gets around 8.7km per litre or 11.5L/100km when loaded but without a roof rack.
With a roof rack, Rhino bars (150mm legs), Superrax carrier with Racksak & solar panels fitted gets an average of 6.2Km per litre or 16.13l/100km.
The economy really plumets if you need to put the foot down or have head winds.
I am currently experimenting with a lower profile legs & different front defelctors.

'93 Factory Turbo Diesel with 3" exhaust and 237,000km, bars, winch....

Melbourne to Narooma, 900km trip a couple of weeks ago, I drove like a grandpa to see what I could get economy wise.

12.1 litres/100km up the coast. (8.26 km /litre)

Gave it curry on the way home via Threadbo for another 900km's and got 13.8 litres/100km. (7.25 km/ litre).

My average is usual about 13-14 litres/100km. (7.1-7.7 km/litre)

For the record litres/100km is the way to go!

'97 GXL Multi-valve Turbo manual, 3" exhaust and safari snorkel. 255K clicks. Black Widow _Affordable_Storage_Drawers.aspx & 166L Long Ranger rear tank. No roof rack or winch. Don't reckon snorkel improved by economy at all.

Winton(Q) area - Toowoomba, 1429 km, 13.88L/100 (head wind)

T'woomba - Winton, 1448 km, 12.84 L/100 (tail wind)

Katherine - Darwin, via Kakadu(3 days seeing sights) 1282 km, 12.3 L/100

Dunmarra - Mt Isa, 963 km @ 120kmh, 13.1 L/100

Blackall - Toowomba, 1235 km, 11.96 L/100

While speed is a big factor with fuel consumption, head, and tailwinds play a big part too. Hit a big head wind and watch the fuel gauge take a dive.

Hooroo...
