We have a petrol cruiser, and tow a nearly three ton van, fuel consumption drops about 20% (average), but does vary depending on the terrain, and weather conditions.
Friend has a 4.2 diesel, and his is similar.
Hope this helps.
Cheers

Trip just completed was 14000++, and we averaged 4.55 ks per litre, as far as around town i don't keep figures, as the cruiser is really only for pulling the van.
Back some 6 or 7 years ago when i did keep the it was about 6kpl, but take into account it was all short running around town.
We have now made the decision not to keep consumption figures because if we want to go somewhere, we are going to go, so bugger the cost .

I've got 4.2TDi 2004 manual Patrol. Around town about 14litres/100km..on a trip this can rise to about 16-17l/100km towing a 1200kg campertrailer on the blacktop sitting on 100kph or go to about whatever! when towing in low-range in rough country. You've asked a VERY open-ended question and I suspect the responses won't mean much as there are just so many variables eg laden weight of vehicle, what's on the roof, speed, terrain, what gear and range is being used etc etc. Good luck with getting something which will be anything more than a very rough guide. Cheers.

We have a 2004/5 GU Patrol, 4.2td with gas injection. When on gas, we easily sat on 80-100kms/ph on a good gravel road recently, towing a 3 tonne 22' caravan.
On the way home the air filter choked up, we ran out of gas, had a horrendous side/head wind and at times could barely get to 65kms/phr. Hubby did say what the fuel economy was (nothing flash!), but I can't remember the details. Something like 17ltr/100kms. May have been down to 14ltr/100kms on the good bits!

He's now considering a turbo upgrade to assist with more power, especially when we are unable to use gas due to lack of supply.

Hi Kim111,
Based on what figures you provided, I wouldn't be too keen on changing anything on that engine. Those figures are very good results given you are towing a 3ton van. As far as the air filter getting clogged, it isn't hard to quickly clean the filter and put it back in.

looking at those figures on straight diesel after the gas choked, they must've been going downhill all the way home.

I stand very corrected... I just checked with hubby, on the way home we did 25ltr/100kms! Absolutely hideous!

As for the air filter, it should have been replaced before we hit the road. As it was, when it was discovered that it was clogged, a simple tap wasn't enough. Hubby cleaned the chunks of oily mud and dust out best he could (no spare....), cleaned it with petrol, let it dry and put it back in. I believe a new one went in the day after we got home...

Hi Trev and Ness,
We have a 4.2L T/D Landcruiser (05) and tow a Phoenix caravan weighing around 3t. Around town, not towing, it averages 11lts/100 and towing between 17 and 20lts. per 100 depending on terain, wind etc. towing we travel at 90 to 100Klms. per hour, the towing figures are after 12000klms. which we have just completed.
Cheers, Bundy

17l/100 towing 3 ton? gee there's a lot of dowhill driving with tail winds around here. Either that, or wishful thinking.

having said that, at the end of a long day's towing, my tug provides me with a recling supermodel on the bonnet with a nice cold one in one hand and a lovely roast dinner in the other but I'm buggered if I could get 17/100 towing three ton on the dirt.

Hi Trev,
These are towing figures only.

80 series turbo diesel Cruiser towing 2 tonne van 17.5ltr/100K various terain but contains some driving over and along the Great Divide

2003 100 V8 petrol series Cruiser over similar teraim to above towing same van 22ltr/100K

Upgraded van now close to 2.5tonne now getting 22.75ltr/100K over similar terain.

This V8 petrol vehicle was 15 to 20 grand cheaper than a comparable 2003 turbo diesel 100 series.

Cheers, Bruce.

if my maths are correct, that's roughly about 66,000ks of petrol saved by going petrol. Taking your lower figure of 15 grand cheaper and fuel @ $1.50 doing a regular (not towing) 15L/100ks . So around three years or more average mileage/kilometerage "paid for". I have used diesels for a good few years now but it's a reasonable argument, as I'm sure Robin, in his 4.8 Pootrol would testify. That may be a conservative estimate but after 3 years the diesel would start to claw that back. The difference would diminish if we were talking used vehicles but whatever, it's an interesting one. All rough figures but it gives some perspective. One other thing I have found is that contrary to popular belief, I have spent no more on maintenence of my current Prado D4D (diesel) than a previous LC100 petrol.

Hi Steve,
A mate bought a 2004 Sahara TD Cruiser for 60 grand about 12 months before I bought my 2003 GXL Petrol Cruiser which I paid 22.5 grand for.

As you can see I have been conservative with my figures concerning purchase price.

My consumption figures are acurate though.

Cheers, Bruce.

yep - that price diff buys a lot of fuel Bruce. I'm doing a similar excercise with the Prado (previously also had a LC100 two cars back but not as much diff with the Prado) it's a very nice feeling on those long trips to fuel up with diesel knowing how far it has/will take you but you pay upfront for it. No simple answer that covers everybody but it's a close one these days. Diesel used to be well below the cost of petrol but as soon as there's a market for it the barstards whack the price up.

just an afterthought, I got rid of my petrol LC100 because of the fuel I was getting through but really, it's all relative and if you get a bit upset every time you need to fill up, just think of what you've saved at purchase. You can end up chasing your tail with this stuff and in the end, there's probably little in it. I can't honestly say one is better than the other on consumption but I have a leaning towards the diesel for other reasons. The same suit doesn't fit everybody though.

7.5 km/lt around town
8.0 km/lt on the highway
Towing our camper... usually 5.5km/lt - 6.5 km/lt depending on head winds and road surfaces
But I don't care, I'm on holidays, when towinng



By the way
When we owned the 3.0 TD Navara,
I go 9.5 km/lt around town
10.5 km/lt on a trip
Towing the Camper... Same as the Patrol 5.5 km/lt - 6.5 km/lt

Have the Mighty 4.2 TD Partol any day

Cheers Bucky

I have turboed my NA 1HZ 1## series cruiser and can get around 12-13 liters /100ks empty and driven conservatively, when towing a Jayco swan (3 adults, 3 kids,a little under 5 ton gross) on recent 7500 k journey the economy varied greatly mainly due to driving speeds and relative winds,

Here are my feul records

I should point out that this history started with the camper on and doesn't really reflect its good side, my cruiser tends to be sensitive to weight and stuff on the roof rack, take away the weight and keep the roof rack clear and behave in stop start traffic and it can give reasonable results.

When comparing landcruiser Turbo diesels, ensure you find out if its either a factory turbo or an aftermarket turbo, big difference in technology and vehicle purchase price, but is reflected in its fuel economy.

i own an old Tojo Sahara 4 litre turbo diesel , went to the Kulin bush races ( WA ) recently , left Australind with a full tank , drove at 80kph ( v slow ) towing an old 18ft Opal van , not sure of the weight but think its fairly heavy , was 306 ks to campsite , then back to Kulin on the Sunday , totalling about 321 ks , to fill tank took 56.14 litres of diesel . I thought that was fairly heavy consumption . not wanting to hijack your thread mate but while everyone is on the subject thought i might get the odd comment or opinion .
