Landcruiser V8 100s Fuel Consumption

Submitted: Friday, May 25, 2007 at 11:50

H2O

Hi,
Just wondering what people are getting out of their 100s V8 Auto? I have a 2006 model with 29,000kms on it and the average I get with 85% highway work is high 17ls per 100kms. On the highway I typically get low 17ls with the best 16.8. I have a set of storage draws and a TJM steel bbar but the rest is standard. I have a mate with a 2004 100s the same as mine and he gets high 13ls on the highway. He has no draws and a alloy nudge bar. Should I be getting better fuel consumption? I told Toyota last service and they said it was tuned right. How can I get better fuel consumption - exhaust?
Cheers
JD

I wouldn't be complaining - best I have ever got from my 2001 4.5ltr is 16/100klms andf I think that was with a tailwind! No weight and driver only.

B/bars do cost a bit in fuel economy, because it disturbs the airflow, but I am not about to take mine off. Pump up your tyres a bit, try uni filter and better flowing exhaust all help. How many ks has it done?
keep it under 100 makes a big diff to all 4bys.

H20,
did a trip at Xmas 7900 klm" half bit half dirt". 4 people. Out west averaged 120 to 130 kph, trip average was 18.528 lts per 100 klm.

From Cairns to Townsville average speed 105 kph.(350 klm) 14.341 lts per 100 klm.

With high tyre pressures - 235/85/16 tyres as per standard model, 100kmh and conservative driving they can get into high 12's whereas my 4800 Patrol never goes below 14 H2O.

Yours is to high , at least do a run with 45psi , you may be surprised !

I've got the same year model as you. All I have at the moment is an alloy winch bar at the front and a Kaymar wheel carrier on the back... and I also have mine converted to duel fuel gas. So I have the gas tank at the back as well.
When on petrol I get about the same as you. When on gas it blows out a bit further to about 19L/100km. Hope this helps. Craigb

What did the duel gas conversion cost and type?

Where can you get it?

Any problems?

Any issues with warranty?

Does the sub tank remain?

Some discussion previously on this forum about using gas in the tropics, any comments?

Have been thinking of doing conversion and further adding to the range,

Cheers and thanks in advance

It is on par with what I get from mine. I have fitted 285/75R16 Mud Terrains on steel rims (the standard 275/65R17 tyres on alloys will go back on when we return) for our Cape trip starting next week. I expect these to make the economy even worse.

Have a 2006 V8 GXL Auto new Jan 2007, (7500km) Bull bar only.

Towing 2.8 tonne 22'6" Offroad van Perth-Derby return (nearly 5000km). Aircon on continuously, + lots of DC power being drawn. 80km average speed.

Best 20.5, av 21.5, worst 22.5. Driving conservatively. BTW Diesel Troopie with identical van average 19.5 and struggled to maintain 80km average speed.

Open Road no van cruise control set at 105km 13.5

50/50 mix open road 110km, city driving 15.5.

Check how fast you are accelerating from standstill. Being as smooth as they are it is easy to accelerate faster than you really need to.

Dont go over 100 if you want good fuel consumption. Temptation is to cruise at 120 + they seem to settle down on the road nicely at 120, less wandering/wobbling and smoother ride but fuel consumption rises considerably.

Where can you get it? Most reputable installers

Any problems? None.

Any issues with warranty? What Toyota won't cover Parnell does.

Does the sub tank remain? No, I replaced mine with a 92ltr gas tank

Some discussion previously on this forum about using gas in the tropics, any comments? Haven't been there yet since conversion.
