Wanted the true Fuel consumption when towing

Hi Rockape,
I have a 2003 Prado auto diesel, travelling around OZ for the last 15 months. I have a 1.8t Windsor poptop with a load in the back of the Prado too (tools, spares, bbq, grog; the usual).
I expect to get 15.5l@100 if the road is undulating with the odd hill/mountain. Up to 16-16.5 if there is a headwind. I have got 14's towing but not sure why except it is usually flat. Of course a tailwind is the best scenario! Around town, empty, I can only get 13's and on the hiway, 12's.
This is the old KZ motor which was known for its thirst - the D4D gets way better figures. (Mr Toyo usually takes a few years to fix things like the engine and the rear door catcher).

As you say, revs to 2000 (90kmh for me), no slowing if possible and constant monitoring on how hard the foot is pressing. I drive in thin soled shoes as I find that helps.

Is this what you want?

Hey Rockape how are ya.
We've got a 5500 odd Km trip Sep/Oct and with the 1HD-T(91 80 series GXL Cruiser) towing our heavy Jayco Swan(1380Kg empty, bone dry, no batteries, no spare wheels, no gas bottles, it would have to be close to 2000kg packed for traveling) I'm guesstimating we will use about 17L/100k's.
Yet when empty, on the H/way I will get as low as 10l/100k's traveling at 95kph, above this and she starts to suck the juice a lot more.
I also tow a horse float at times and it is about the same consumption as the camper.
City driving is a real fuel chewer, with the stop starting you can nearly see the gauge move each kilometer traveled.

I, like you drive smoothly, no racing away from a stopped position and only brake when necessary, watching the road ahead and preparing for a change in speed. And as you tyre pressures make a big difference too, I wouldn't be telling you anything new there. I run 42-44 psi on the H/way, sure it's a bit rough at times, but it helps and I'm getting K's out of my tyres.

I use this site to help keep track of my fuel consumption. Fuelly, you can search for similar vehicles to get some idea what other are getting.

Hope this is of some help.
Cheers.

My RRS - 2.7 TDV6 (2.6t unloaded) gives about 8l/100km on the road (110/120kph), about 9l/100km around town and when towing my Jayco campervan about 13l/100km at 110kph.

Towing up a hill on the highway I will see up to 80l/100km but along the straight and level about 6l/100km - averaging about 13l/100km overall.

Rockape,

The fuel figures I have recorded for my 2004 NP Pajero 3.2 L turbo (pre common rail & second hand), travelling with van attached are as follows. Two trips a year apart with a 2.1 tonne low profile van (Coromal Silhouette) show averages of 14.5 L/100km over 11,400 to Qld, return. Then 10,400 km trip to Darwin, return same van similar conditions – (read rushing ,100-110kph) achieved 14.3L per 100K. Van rarely unhooked on both trips.
Followed that this year with 2.5 tonne full van (Supreme Spirit) to Darwin again and back home with diversion to Exmouth – total 11,405 km – avge 17 litres per 100k. The avge going north was 18L/100 and 16 on the home run (less rush). Extensive use of the ‘auto pilot’ on all legs to gain some relief from sciatic problem. Loading only varying from day to day depended on water in tanks.
Take the van off and avge over several years is around 10L/100 70% city 30% highway.

Cheers - Phil

G'day Rockape,
I don't rely on the on-board trip meter/computer for fuel consumption figures and keep all fuel purchases and distance travelled in a spreadsheet. I average low 9's around town unladen, high 9's on the highway 'cause I give it some and 14's when towing. My van's ATM is 1900kg and I load the car to about 650kg, 50kg within its limit.
It is Nissan's latest incarnation of the 4 pot'er with 140kW and 450Nm. I always tow in manual mode and find that I use 4th most of the time; 2100 rpm gives me about 95kph.

Thanks to all those who have replied with good honest data.

I and others appreciate your answers, it also gives a wide variety of tugs and weights.

Thanks all
RA.

Hi, I am just on my way home after a round Oz trip towing 2.5T Van behind my LC100TD. I have kept a close and accurate watch on my cosumption and the most common figure I get is 16.1Lper 100Kms.
I have run as low as 14.3 on a flat run thru the Great Sandy with a nice wind behind, and as high as 17.4 crossing the Nullarbor into a stiff breeze. (This meant I ran in 4th at 85Kph, for most of one day.)
I normally run in overdrive at a about 90kmph, and kick to 4th at the first sign the motor is working.
I used to always tow at 100-110kph, and sometimes more, a few years ago. I was always 17- 18kph then. (Stupid too!)

As an aside my mate had a petrol on gas LC100 a few years ago and left Alice Springs heading north into a very strong wind, towing a 2+T van. He was using 48L of gas to the 100. He came home and traded it in on a TD!!

Rockape,

Don't think I have put this graph up on this site before.

Vehicle: 2005 100 Series Landcruiser GXL Diesel Auto
Standard: No mods from new.
Tyres: Put on 285X75X16 BFG Muds
Exhaust: Put on 3" mandrel bent exhaust.
Chip: Installed D'tronic.
Trailer: Towed a light camper 5,000km to the Alice and back.

High numbers are sand.
Low numbers unloaded no roof rack.

Hi Rockape

I have a Holden Adventra AWD, 5.7lt Chev V8 petrol, weighs about 1850kg unloaded, usually have 4 on board and about 350kg of gear in the car. I tow a Kimberley Kamper, which weighs about 1500kg when fully loaded, with boat motor and all the gear.

Unloaded car only around town I get about 20lt per 100k.
Bathurst to Sydney return (Lots of mountains) 13.5lt per 100k car only
Hwy/freeway 12lt per 100k car only.
Towing Kamper flat country (Bathurst Echuca rtn) 15.5lt per 100k
Towing Camper Hilly country (Snowy mountains) 17.5 to 18lt per 100k

I am quite impressed with the vehicle as a tow vehicle. It is big and comfortable, is reasonable on fuel and seems to do it pretty easy, rarely needing to change gears. I tow at 100km/ph as at this speed I am doing about 1850 - 1900rpm. If only you could get a long range fuel tank as 75lt is ridiculous.

Regards


JAs
