I've got a 91Toyota Landcruiser GXL Turbo Diesel and would like to know the fuel consumption of other owners. Being a turbo diesel, I expected it to be fairly economical but am finding it is fairly thirsty. Especially travelling at over 100kph.

I have the same model and mine has done about 206 km. For a 2.5 tonne car I think I am getting good consumption at around 13l/100km around town if I drive relatively conservatively. I have got it down to 12L if I drive gently. If I flog it around town it gets up to around 15L. On the freeway it is about 13-14L if travelling over 100-120 km/h.

It's 5th gear is fairly low so to get good economy travel at or just below 100km/h. I am getting larger 16 inch wheels and 305/70 tyres next payday so will see if highway improves. It will take a bit more to get going though I think.

I had a 3.3 litre Nissan MQ patrol short wheelbase diesel and the economy figures were on average similar but sometimes worse and it was a good 600kg lighter so I think it is pretty good on the fuel.

When I drive it on soft sand though it really starts to drink the fuel. Haven't measured it exactly but reckon it must be up around 20L/100 km.

Hope this helps

Hi Charlie
Do you know the 305x70 is thesame diameter as a 295x75 but wider (33 inches diameter)? You can get a 315x75 tyre that measures 34.5 inches diameter, and they will fit on a 16x8 rim, but you would need a suspension lift at minimum to get guard clearance. These tyres would give you 10% fewer rpm at 100km/hr and substancial increase in footprint and traction.
Always good to remember you can buy thesame diameter tyres in 15 inch aswell for less.

Thanks Dozer,

You weren't the big guy in the Matrix were you? Just kidding.
The problem with the 15 inch tyres is that the majority aren't load rated for the cruiser. Even the Cooper ST's in 12.5x33r 15's aren't rated enough for the cruiser. This can give major insurance probs in case of a crash related to tyre failure.

I am going up to 16's because most of the metric tyres are load rated. I hear you about the cost though, they are definately more expensive.

I would love to put 35 inchers on but would require too much modification for my budget. I have just put in a 3 inch lift and bloke at fourby's in Bris. said they wont put them on without a 5 inch lift at least.

Will just have to do with the 12 inch 33's. It will still go better on the sand than the 31x10.5r 31's that I have at the moment. (which aren't load rated and illegal at the moment)

I have a 4.2lt turbo diesei Toyota 1998 intercooled with about a tonne of 'extras' including a rooftop tent, awning, arb everything, long range fuel tank etc etc. I keep the cruiser fully packed with food, tables, chairs, tools etc ready for an instant take off on Friday nights after work. Never weighed it but reckon it must be closer to 4tonne than 3 tonne. I did a 2500km trip last Easter and kept very accuarte fuel data and averaged 15.5lts per 100km. Very little off-road stuff and mostly at 100 - 110km/hr 5 - 8 hours driving per day. I noted that where I used to manage to cruise at 110km/hr at about 2200 rpm I now need 2500 rpm with the rooftop tent and full roof rack.
I wont win any efficient fuel usage awards but hey...I did it in comfort and style :-)

Have 1990 GXL T/D, have roof rack and extras etc. On highway I get 8.5 Klm/litre which is travelling on freeways around 115kph. Around 100 kph get 9k/l I had to stay in Sydney for a period where I was getting 10.5 klms/ litre in built up areas which really suprised me. Travelling on freeways towing camper (approx 1.4 tonne loaded) at a speed around 110 + it drops to 6.5 kh/litre. Dropping speed to 100 kph I get about 7.5 kh/litre whilst towing. Vehicle done 280k and injectors getting serviced soon. (Sorry I don't talk in litres/100 kilometres but it is arse about for my liking, kilometres per litre much simpler to work with and to calculate distances with fuel etc.)

I think they are economical for its size and power. Reducing speed does increase economy a lot, plus get to see more.
