I'm about to pick up a new LC100 Petrol V8 & was wondering if anyone can comment on the fuel efficiency I'm likely to expect.
I'm trading in the trusty VT Dunnydore V6 for the LC100 & I was geting around 13lt/100km in city driving & around 10lt/100Km on open roads.
I know the Cruiser will be a "tad" thirstier, but how much should I expect to get out of it....

If you double the figures for the Dunnydore you would be very close to the mark.

G'Day Gregster,
In answer to your question ... "a large tad", but really mate, if your concerned about the fuel efficiency, you should'nt be getting any large petrol V8 4x4.

I wouldn't quite double it.

Whilst I'm not sure of the V8 , here's some others.

my 4.5 Petrol Patrol , gets approx. 16/100 Highway , 20/100 City , and 18 - 20/100 Towing my Camper Trailer.

A mate has a 4.5 Petrol Cruiser , with similar figures.

I understand the 4.8 Petrol Patrol actually gets slightly better fuel economy then mine . . . but only by 1/100 or so.

I suspect the V8 would be around that mark somewhere depending on how heavy the right foot is.

According to 4x4 Australia Magazine April 2004 issue No. 243 the fuel consumption figures for the V8 (average on-road/off-road) were 18.2 L/100KM.
Average towing (1500kg van) was 28.5 L/100KM

Before i added all the aftermarket gear... roof rack etc... I was getting at best 15lts per hundred driving economically.....average about 18 lts per hundred.

now I get 20lts Per hundred average using ULP..
Towing a caravan 25lts per Hundred @ speed Limits

Using 98Ron.... 25% better normal driving normal conditions
Using 98 ron towing .. works out about the same . better milage but you pay the balance for it

I have a June 03 GXL LC approx 30,000 km now...

Hope this helps..

Point of interest .. when i removed the tyre from undedneith and put on a wheel carrier my fuel consumption increased abnormally so...
I put a thin tyre back undernieth for the just in case as well as the one on the wheel carrier and the fuel consuption returned to what it was...

Must mess up the flow of air under the vehicle more then you would think...

Hope this has helped.

Damn - I now know why people buy defenders! I get 10L/100km out of mine doing a mix of city and 90km/h driving. Worst figures have been on the freeway, where I get 12L/100km, but that was doing 120 most of the way.

Out of curiosity, what sort of L/km are other diesel owners getting?

Hi Chris,
They are about the same figures my 2.8td patrol gets. What size engine have you in the defender.
Keep in mind I try to stay under 100ks.

In my 2.8TD Pajero I get about 11L/100km around town and the worst I've got is about 12.5 with a bit of offroad and towing included. Got my injectors overhauled today so will be interested to see the effect!

I have filled the Prado twice since new. 150 odd litres both times. First full refill I got 12.1L/100km and second fill yesterday I got 12.0L/100km.

3.0l intercooled 1KZ-TE turbo diesel. That's about 23mpg so I am pretty happy with that considering that my driving style does not exactly spare the horses!

Went from a VS V6 wagon to the V8 Landcruiser. Weekly fuel bill, 400km early peak hour, plus weekends, in Sydney, went from $60-65 to $80-90 per week. Mines an '05/03 with 37k on it. Open road varies, load it up with kids (4), roof rack, trailer, blow the oil burnes into the dust and you will see an increase. But hey you know it, I know its a V8. To live with, realistically expect 20 to less than 30% increase. Looking back I am happy with my decision. I also use Shell optimax, what you pay for at the pump you get back in economy and performance. Good luck

Frequent checking of the computer during the trip indicated a fuel consumption rate less than the above and the computer recorded a reading of 8.6 ltrs/100klms after refuelling in Melbourne. Temperature and possible inaccuracies in fuel pumps, notably at country locations would explain the difference between pump and computer measurements. .
