This may sound like madness....but we just bought a caravan (get it in a month) and would like to know if anyone has any fuel consumption figures for towing 2000kg caravan with a LC100 4.5 Petrol?

We know the figures are going to be high, but would like to know what other people's consumption has been (without a gas conversion!!!), and if there is anything we can do to help with usage (turbo charge etc). We currently tow a campertrailer (about 700kg fully laden) and our fuel consumption doesn't change from when we are not towing as we only go at 90km/hr when towing to try to balance out the fuel usage.

Hi I only tow a camper at around 16 l/100km also at 90kph on petrol.
18/20 on LPG.
You can get a chip to give more power / better economy.

Turbo, a chip with the turbo apparently is necessary otherwise the standard computer can't adjust the fuel / air mix properly thus not giving you all of the benefits.

I can't offer anything purely on the LC, but we did go from towing a 700kg camper to a 16 foot van, fully laden 1700 kg and found fuel usage went up by about 35%. About 20L/100km.

This was with a 3.5 V6 petrol.

Also towed the same van with the oldies 4.8 Patrol on LPG and it used 31L/100km. That was hooking along at whatever the speed limit was; when it was 110, we were doing 110 and we held the speed limit up hill and down dale. Simply used whatever gear and revs needed to maintain 110. So to speak, I was not driving for economy.

Use this for what it is worth.

Can only give you an estimate of my uncle's who use to tow with a 80 series 4.5 auto with roughly same size van (20 foot) toilet shower etc and was around the 25/27 Litres per 100. He updated to 100 series T/D and now uses around the 15/17. But I must say he doesnt baby it and would sit on 90/100 klm when out on the flat open road running cruise control. Regards Steve M

I have 2001 LC100. petrol 4.5 with auto box.I tow a 2002 Windsor Streamline 18' full size van 1700 kg tandem,my rough calculations on fuel I use ,is between 19 to about 24 lt per 100 km. [no gas]
Back in 2000 on a trip to Darwin with a turbo dieseil 60 series L/C and 14 ' Golf poptop van we were getting about 12 lt per 100km . On the first day off that trip we doing about 105/110 and fuel was noticeable in usage so we dropped our speed to around 90/95 and noticed a big difference. As someone said to me once "you have to feed the horses" predication $150US a barrel not far off? Back to horse and sulky.

HI all

Thanks for your replies. Kinda puts my mind at ease a little...I am hoping not to go over 30 litres per 100/k. Still sounds alot but that would still give us a range of 900km with our long range tanks. All a bit scary but should be good in the long run.

Thanks again
