Landcruiser 4.5 Towing Fuel Consumption

Nick

Can't speak for the Tojo, but I had a V8 Disco ... bloody thirsty.
About 20l/100K if you hit the loud pedal a tad too hard. I would be surprised if it wasn't similar.

Cheers

Towing around 1600kg I'm getting through 28L/100ks. That's at around 100kph in a 4.5 100 series. Did slightly better than that when I had a V8 Disco, but when not towing, the Cruiser was slightly more economical.

My Petrol Patrol Auto 4.5 , gets between 20-22/100 towing my 650kg CT.

Thats sitting on the posted speed limit.

It looks like you have a well decked out ecconomical truck. I reckon I would think very serioulsy before getting a large petrol 4wd. I would consider another diesel or at least a gas conversion if it's a petrol!

Hi Nick
I thought the purpose of petrol engines was power without regard to economy. I can remember in the days when fuel was cheap the Bronco used 25/100 regardless of how you drove it, what a shock going to diesel and get 12/100 towing 13.5/100

Hell those figures are thirsty - and that ecomomy severely compromises your range too - if you want to be into remote areas travel at some stage, you have to carry so much more fuel to get between those distant fuel stops- there's something to be said for the "different", yet totally adequate power band of turbo diesels and the resultant lower fuel consumption figures - a TD around the 120kw mark (4 cylinders even) would do handsomely with your indicated trailer. But that was not your question and I'm possibly rambling ..........:0)

Bro just got rid of his LC and went to a HiLux ute due to fuel use mainly. 25>28 was regular towing Campomatic. Could be worse "off road" depending on conditions.

My 4.5L 100 series towing camper trailer with total load weight of 1100kgs (car and trailer load) used on average 20L/100kms over 9000km trip.
I now own a diesel 100 series. average around 15-16L/100kms with same load but bloody SLOW.

Towed a slightly heavier and not very aerodynamic trailer, the best I did was 21 L/100 K, (worst more like 24-25) on a highway, best without a trailer and no load has been about 14. Now got a lighter and more aerodynamic camper and do more like 16-18. Looking to a diesel now though for longer legs and better economy....

GXL 100 series turbo diesel Cruiser, towing a 2.5 tonne (all up) caravan, from Perth to Port Hedland & back over a 4 month period, including some slow bush work (not much) - overall consumption = 17.5L/100 kms. Could hit the 110 speed limit no probs and hold it all day if needed, but sat on about 90 to 95 kmh mainly. Oh - and a cruise control. that helps.

I'm an ex truck mechanic and I look at it like this. Once you reach a certain engine size and vehicle weight, petrol engines can't beat a diesel for economy. You don't see too may petrol engines in trucks these days do ya?

3 litres is about max for load pulling petrol engines after that they get thirsty.

Imagine the consumption of Freightliner or Mack if it had a 15 litre petrol engine in it!!

Discovery 3 2.7 td towing Tvan (1200kg loded) 13.7 l/100 at speed limits, over 6500kms including 1000kms off bitumen

Jeepers I knew they were hard on fuel but not that bad.Any one got a 100 series diesel they want to sell!!

I have a 4.5l GXL 100 series auto that I tow a 1500kg poptop caravan with. Towing I get between 20l per 100 to 23l per 100. Usually tow between 90k and 100k per hour but occasional excursions to 110. Surprisingly consumption does not vary much between flat going and driving through say the mountains. Speed and head winds (actually worst 3/4 on rather than dead ahead) seem to be the main impacts to fuel consumption. Usual consumption not towing is in the 16l to 18l per 100 range.

Hope this helps.

Towed a Caravan from Cairns to Perth ( so far ) with 200,000 + klms on the clock and averaged 20 - 25l depending on winds etc. We look at the big picture..... What price do you put on the experience of seeing this great country.Bugger the costs - lets go and have a look at that !!!!

I have an '95 80-series 4.5L 5-speed manual Landcruiser, running on regular unleaded petrol. When I'm not towing, I regularly return 15L/100km when highway driving at 100kph (around the city it goes up to 18-20L/100km). When I put the campervan on the back, at an all-up van weight of some 1100kg, I get about 18L/100km cruising at 100kph on the bitumen.

At hiway speed, in your big petrol engined 4x4, you can confidently pull out to overtake that Road Train on the way up the hill. Even though you are fully loaded with gear, fuel, supplies, and your trailer. If you were in the same truck with the Diesel option......... you just have to wait till you get to the top of the hill, and take him on the way down....provided there is plenty of room and the Road Train doesn't also pick up speed. Possible exception to that rule might be the Tojo 4.2 multivalve job in the LC100. Amazing balance of power & torque there and generations ahead of enything else......at least at present...(no I don't own one)

The diesel will be cheaper on fuel, but will need fresh oil every 5000klms or less.
The Petrol will drink more heavily when worked, but you won't even feel the camper trailer behind you on the hills.

If you tow heavy stuff around, you will want torque, as well as power, so if you go Diesel....get a big one. The little four pot turbo's might give you all their torque at really low engine speed, but 100% of a smaller amount, is still a lot less, than only 75 or 80 % of a larger anount......such that you get from a Petrol engine or a big displacement T/Dies. The harder the work the machine has to do......the stronger the machine needs to be..........or it will always be operating at it's max capacity, and will therefore wear out more quickly.

Back before the motor vehicle, the horses that pulled the Drays were bigger and stronger than those that were pulling the Sulky....Horses for Courses or something.

Happy hunting
