Hi Barney, I have a 04 4.2 td cab chassis with 3" system and whilst not towing , have a slide on camper ,all up weight 3.5 tn and averaged 7.2 over 25000km not counting the first 15000km run in. Usually travel 90-95 occassional 110. Fair bit of off road stuff in that as well.

Hello Motherhen,

Just curious about your 7 - 7.5 km/litre? We have just finished a 6,100k trip into NSW and across to the Alice and back with our GU III 3.0 manual. The vehicle was loaded to 2.98 tonnes (weighbridge, no trailer). We were mostly cruising between 90 -120 kph as the conditions allowed. Below are our fuel figures.

Km Miles l/100km km/l mpg Fill points
435.6 272.25 10.10 9.90 28.10 Caltex - Devonport

414.5 259.06 10.41 9.60 27.25 Shell - Westgate North
The heavy 4wding was to the easy of Arltunga, through a 4WD Adventure trail (took over 5 hours to cover 100 km, all low range work). That's a trip average of 8.42 km/l. Around town I am regularly getting 8.7km/l. We haven't done any serious towing yet, so I can't comment there.

How does this compare to other 3.0 GU's ?

Cheers,

Peter

Hi Peter - you're doing very well then. I only did a couple of tests on it when we got it (it was not loaded at the time), generally on a long trip rather than the short running that is part of its life at home, so expect we would be getting worse overall. Ours is auto. I have not ever considered use of the air conditioner which may be a variable factor.

In 2003 we towed a small wind up van. I didn't keep the same kind of records, but probably got around 6 kms, travelling around 110 when on the main roads, a bit slower on the rough stuff.

In 2004 we raced to Qld to pick up the Bushtracker, and averaged 7.65, travelling generally fairly fast. On the way back towing (mostly around 110 - 120) 4.83 kms.

2005 and 2006 i kept fairly good records, and different fuel fills give rather different readings, but overall, during the past two years trips we have averaged 5 kms.
