Patrol GU 4500 fuel economy

wow, i think there is only one worse petrol guzzler out there (petrol landcruiser). I can give you some non-towing figures. We go 100kms on 20litres of petrol in the city and 19 litres in the country and 29litres in sand. Our friends discovery turbo diesel 2 point something litre manages 10litres per 100km and does everything we can do and goes further. Well thats the figures he gives me anyway.

I have a 4500 1998 Petrol, and knew that consumption would be an issue when I purchased it.
Now "Shirl" has done 70,000 km, so it's "settled". Best advice: Speed = thirst. Don't drive over 110 kph unless you have shares in BP.
Last week did Adelaide -Googs Track-Gawler Ranges-Adelaide. 2000 km. Averaged 19 litres/100 km. Weight was 3.2 tonne at commencement of Googs track- full of water, fuel, supplies etc. On that section got about 21 L/100km.
On the black top highway at 105 kph (by the GPS), and using the cruise control, got 17 L/100Km.
"Shirl" has a roofrack with a canvas bag on top with swags etc inside. This gobbles fuel c.f. no roof rack.
Hope that helps.

Peter the above echo my info. A recent crossing of the Simpson Desert - Oodnadatta - Birdsville 700km, Petrol Patrol 180 litres, Petrol Prado 118litres, Diesel Cruiser and Disco both less than 100litres. All vehicles were similarly loaded and travelled at same speeds. In 3 words .... very, very thirsty!!

Yes the 4500 is thirsty. But consider:lower purchase price; reduced costs with half the frequency of oil changes and filters, etc. It takes a loooong time to recoup those extra costs, as would for a gas conversion.
And the 4500 petrol is a torquey number - i.e. it is very easy to drive in most conditions. So I am very happy with it, and driven steadily it's OK on fuel. At the time of my purchase, the 3.0 L diesel was years away. The diesel option was the rubber band known as the 2.8 turbo. If I was buying today/this week I'd find it very hard to go past the 3.0L diesel. But I bought 4 years, ago and although it was my umpteenth 4wd, it was my first NEW 4wd. I still think it's a great unit. So i would not discount the notion of a petrol . They certainly are priced right to get into a top 2nd hand unit for $ 30 K. Cheers. Rick
