4.5 Lt Petrol Landcruiser Fuel economy

Hi Ozzy, sounds a little bit thirstier then I have heard. I have heard in the vicinity of 22/23 for the 100 series and 20/22 for the 80 series. This is one of the reasons why I didnt get one. Dont know what tyres your running but have heard mud tyres can increase the fuel by a few Litres per 100 ?? Only what Ive heard. If this seems to be normal consumption for yours then maybe a switch over to gas might be the go. Tour Boy on here has his on LPG and loves it so might be worth a thought. Thats very heavy considering my boss get 15 per 100 out of his 4.7 V8 100 series on par with my prado. Hope you sort the problem out but I dont think you have one I think thats just the way it is unless things have changed since owning it and you have worked it out previously and it was lower. My prado was high the last 2 fills presuming its due to the colder weather and wife only doing short runs in it and not totally warming up. I have also been filling up at a different servo so am running both tanks down to M.T and refill at usual servo to see if that makes a difference which I have heard people say it does but mainly on diesels not unleaded. Have you also changed servos at all ?? Just a thought Regards Steve M

3.85km / L

I get about 4.55 km / L in town but I am running a prototype fuel saver so can't comment on the standard consumption.

I do know some pumps are out of calibration. I filled up at the Shell the other day and the 90L tank took 104L and the reserve light had only just come on. I am waiting for Shell to contact me and tell me the pump is 10% out. The manager was going to contact them and have the pump checked.

Hi there

We have a 4.5 Petrol 2000 GXL model Cruiser, she is thirsty as. At present running around town we get about 340km on the 95 litre main tank. On the highway towing campertrailer we get about 22 litres/100km sitting on 90-95k/hr. We are pretty happy with that as we were expecting alot worse, and seeing aswe are travelling around Oz the highway consumption is more important to us than what we use running around town.

We have just discovered a fuel leak so hopefully when that gets fixed things might improve!!

We have 170 litre sub tank, ARB winch bar, snorkle, winch, roof rack (usually a bag on top full of stuff) dual rear wheel carriers with 2 spares.

I have a bog standard 4.5l petrol auto 100 Series. Returns around 16/17 Litres per 100 country, 21 to 22 litres per 100 towing a 16ft poptop at around the speed limit.
Do not have city figures as I live in the country, but some city miles would be included.

Any extra weight or drag (wind resistance) will add to fuel consumption. Speeding, heavy accelerating, hard braking all contribute to a driving style inconsistent with economy. I was once advised that if I wanted to improve economy, try driving (imagining) that you have an egg placed under the accelerator pedal - the object being that you don't inadvertantly break the egg.

It's a good idea to use 5 litre, 20 litre or known size container to check/verify output from servo pumps. Although not intrinsically accurate at least you'll get a pretty good indication.
Another good check is to multiply cost per litre by say 10 (1.25 = 12.50) then watch the pump, when it reaches 10 litres just check that the dollar cost displayed corresponds, in this case $12.50 just another way of checking the 'mechanics/electrics' of that particular unit.
If sometimes you do manage to 'squeeze' a bit more into your tank(s) I wouldn't be too alarmed as it can depend on the slope of the driveway/forecourt (away from the pump - you'll often get more in), how quickly you fill and if you stop at the first cut-off, 2nd, 3rd etc or until you can't get another drop in. The difference can be anything from 5 - 10 litres (in some cases even more).
It may also depend on the ambient temperature too, colder means fuel is more dense, hotter the fuel is more expanded. Least that's what I was told by a Servo Operator (friend) some time back. Mind you, I don't think you can ever expect to get anything for nothing from the oil companied. The shape/design and plumbing set-up of your installation might also have something to do with inconsistencies. You could also be getting air locks in the fuel tank breather lines which would have an impact or if the vehicle/tank is not vented correctly there could be spaces left at the top that you can't ever expect to fill. Lots of variables, suggest you use a bit of lateral thinking. Where I live, industry is required to have their pumps checked for accuracy and tagged by suitably qualified technicians. Don't know if it is a foolproof method although I've never had reason to qestion the accuracy of servo pumps.

Hi Ozzy,

I'm feeling a tad better reading your comments about the cruiser. We have a 4.5 Patrol, twin carriers, bullbar winch, rooftop tent, draws etc etc. and generally return 24-26litres / 100km.

I found since I put the Kaymar rear bar on it's been quite average. Before the rear bar and without the rooftop tent I would get 18-20l / 100km.

We don't come across many people with petrols touring, for good reason obviously... I was chatting to a local in Innamincka when we were stuck there for 7 days a couple weeks back, fuel range came up in the conversation... It wasn't long before the entire town was blown away by our consumption figures!! (all 150 of us stranded)

I have a 2004 LC 100 series V8 get 14ltrs/100kms sitting on 100/105kms, going over to SA last month on the nullabour sat on 95kms cruise control on and got 12.5ltrs/100kms, once you get up around the 115/120kms it will suck the juice......with the Van on the back (2000kg) get 18ltrs/100kms

Ya didn't say if its auto or manual.

I have a 4.5lt in a troopy (manual). I get 5.6ks per litre on petrol and 4.6ks per litre on gas.

Hi Ozzy,
I get 18-20l per 100km on gas running up and over the mountains every day. 18 with the boat (4.8m) going up the coast and around 14 l 100km on petrol in the mountains.
I would no doubt get better milage if I drove it differently and reduced the time warming it up.
I'm also running 285 muds, lift, bars, wheel carrier, drawers, fridge and all manner of other crap incl snow chains all the time so that doesn't help.
I have the twin LPG tanks setup and still have the original twin petrol tanks (more weight)
Regards
Tour Boy
