Quick poll on fuel economy with BT in tow

HI Rick & Julie,
I don't think it really matters too much on the type of vehicle as from what I have found talking with others, and indeed our own aplication, is that the rule of thumb is that your fuel usage will double when you hook your BT on the back.

Not towing and highway cycle we can do 13.5 L/100K in our V8 Petrol 5 speed auto 100 series KROOZA.
This then becomes an avereage of 27L/100k with the BT on the back.

Our worst towing is 30L/100k when travelling the New England from Brisbane to Armidale up the mountains.
Our best towing is 22L/100k when on quiet outback roads and we're just "Putting Along" at 40-60KPH taking in the scenery and wildlife and or being kind to the BT and it's contents whilst traversing the corrugations.

You must be getting excited now Rick..after all we're in the same year for pick up now.....when is it again?? Mid June I seem to recall....how many sleeps??

Hope this helps
Cheers
Rick & Julie

A lot depends on the driver but have found where I get the best fuel economy is as follows.'04/TD without BT 11.2/L on110 kph - with BT '19 (approx 3300kg fully loaded plus 275 L fuel and boat on cruiser ) 95kph/1800rpm 17.8k/100 .Pushing head wind or heavy going offroad worst approx 20>21 L/100.

I replaced my sub tank with 185 L aftermarket because I carry 3 jerrycans of petrol for outboard and generator on the draw bar.It depends on where you are going to travel have found the extra 140 L comes in very handy and would do the same exercise again with next vechile.

Ftruck 7.3 lt deisel no van 14/15lp100k
Ftuck and BT 22/24 lp100k just shy 9 ton
As for fuel, I say I have approx 1000ks road, 750 dirt.
It's rare for us to use the jerrys for vehicle fuel, normaly genset and boat.

Now a mate just got a new 200 and he say's he will not be adding an extra tank, as we have found fuel available ( at extreme price's ) about 300 to 500 klm's apart almost anywhere in Aust.
I think he may be going to rely on my extra supply.

Sambo said he took his van 18ft BT down to the burdikan at 4.5 lp100k driving hard and fast, on the way back he got better about 5.5 driving more normaly, 200 has only got 3000ks on it. so even if you do a rough average of 4.9 to 5 lp100k that would put you in the ball park.

If we have to do any distance betwen fuel stops I work on 25lp100ks and I am always safe. Fuel consumption is very dependant on your personal driveing style, I can tell by the fuel guage when Jan has driven. ( no comments please )

You know you've made it in life when all of the above is of no interest......yo

Hi Rick and Julie

I raised a similar question when we first picked up our BT in 2004. We were heading home at full speed as we had a very limited time frame. Refer to post 888. Overall, fuel consumption wasn't a lot different what ever tow vehicle was used.

An average, we got 5 kms per litre towing with the 3 litre Patrol auto, and expect we will get similar with the F250. We get 7 kms per litre from the Patrol when not towing. Apologies to the modern generation who want to quote litres per 100 kms. With the Patrol, we do not tow in overdrive, and my husband watches the revs.

For calculating fuel, we multiply the kms ahead by 4, to allow a good safety margin.

Around 16 litres/100k city driving, no van.
Country driving,no van 14 litres/100k

F250 4500kg and 21' BT 400kg 4km/ltr 24-25 ltrs/100km sitting on 97 km/h.

Can get a range of 1000 - 1100 kms out of a 270 litre tank, usage 260 litres.

Discovery 3 TDV6 11l/100km without BT, 18 when towing 20 ft BT fully loaded.

Normally aspirated 80 series LC with 441,000 on the speedo. Pulling a 3 tonne BT. Mostly full throttle all the way (but it loves it!). LC has extractors, hi-flow K & N air cleaner, ram snorkel.
Figures: 4km/ltr regardless of wind (25 ltrs per 100kms). The LC usually does 7 kms/ltre (14.5 ltr/100 kms) on its own carrying about 3 tonne all up. I am presently experimenting with a HOG (Hydrogen Oxygen Generator) which cracks demineralised water and feeds the resulting hydrogen and oxygen just downstream of the air cleaner. Initial results are 7% increase in economy with a much improved torque lower down. Still to do extensive testing but will put my results on the BOG site in about 2 weeks.
It all a worry!
