FUEL CONSUMPTION

[Shifter Junior Member Find all posts View Profile Close Shifter]

Can you do 110 in Tassie without falling off the edge?

It's so expensive to get to the big Island we try to launch ourselves in an attempt to save money - haven't quite got the trajectory right yet!

God's little acre!

We have an 04 with auto just done 200,000. currently getting 17.5/100. Mostly used as school bus during the week, has 265/70/17 mtz's & roofrack with spotlights, injectors have been serviced recently. I've been told by my local diesel guys that its all because of the tyres & roofrack, but I refuse to except this as the only reason as I have read in these threads, others are getting much better results.
I have also been told a simple fix is a diesel chip, but I'm not convinced.
Any ideas or help would be much appreciated

18.8LHK at 46km/hr average speed along Sandy Blight towing camper trailer, 25psi. Gotta love that bowser at Warburton at $2.35 litre. Managed Warakurna to Alice on 152 litres.

There is definitely something not right, and I wouldn't chip it before you know what the problem is and fix it. My worst figures were 17.8lph with lots of mods (and weight) towing a camper up a pass at altitude. I've done 260k.

Does it blow any smoke at all? Does it lack power at all? Do you have a boost or egt gauge fitted? And silly question, but does it drive straight ie brakes aren't binding slightly?

I have not noticed a drop in power but it does kick back a lot more if towing. Smoke is very minute. no gauges, and no binding.

Best so far is 8.9 l/100 highway lots of traffic at 80kph. Worst close to 40 l/100 towing the camper on Laura to Maytown track. On that day we did 40 km in approx 8 hours. Never needed recovering but just slow going.

The idiot light came on 80km from Tennant Creek. I'd done Alice to Binns Track, Frew Loop, Policemans Waterhole, Hatches Creek, a fair bit of running around this location, towing my heavy camper sitting on 90 on the dirt at 30psi and 100 on the highway at 42psi. The picture was taken when I drove into the servo at Tennant Creek. Says I still have 11.9 litres remaining and this was spot on. I have never ever been with less than at half of one tank left before. The average was around 17.4 for that part of the trip.

I have a 90 series auto 1kz. When my wife was driving it, and doing heaps of short trips the fuel was around 16-18l/100km. Now I drive and it gets a chance to warm up and doing more kms, I'm now getting high 12 to high 13 running around town. I'm running 238/85r16 mt,with xrox bar, sliders snorkel.

I'd take a look at your air filter, fuel filter. Tyrepressure, and when was the last time your auto was serviced? Also what economy where you getting before the injectors where serviced?

Just filled up the old 1kz manual.
1320k squeezed the ass out of it to fit 142ltrs.
Use included some 4x4 small amount of towing maybe 200k of 800kg's
Plenty of short trips from home over 3 week period.
Pretty happy with that for what it is.
Tyres 265/70-17 bfg a/t. So actually a few more Klm's than that, probably 1350k.

Fuelly tells me I get an average of 11.6 litres per 100.
My mechanic gave me a new brand of full synthetic oil on my last (140k) service. Asked me to monitor fuel usage, it dropped to 10.6, and some that was the old oil.
If it is good as he was told, I might get back some of my lost economy from all the mods (tires had the most impact).

Next fillup will tell the story..

Mate something is definitely not right at all there !!

Just did over 2000km's up the east coast in our 2004 1KZ, 245k on the clock. start of our oz adventure

Prado is maxed out in weight, 2"lift with roof racks and a Thule cargo carrier, Towing a 21ft 2.5t van and we avg around the 18l/100 sitting on 80/100km/h .

Van off i avg around the 13l/100 with roof racks/thule pod/lift.

I couldn't even imagine driving your rig hard would get you figures like that

Have you been filling it up with petrol gmhgq?

Does anyone know the weight of a 1KZ engine?

[Bushbasher Out of control poster! Find all posts View Profile Close Bushbasher]

I've heard that a Colorado dual cab gets a little over 12 litres per hundred kays at a steady 140km/hr.

Here's one for you guys...I'm in Melbourne and got an '09 D4D GX (6sp manual) with 85,000 on the clock. It's bog standard with sovereign bar, only mod I have on the car are 265/70 Goodyear Wranglers AT's...yet I'm averaging around 11.5-12L/100 combined. Don't have scangauge or anything, just working out how many KM's I'm getting out of the litres I'm putting in, for example the last 20L top up that went in got me 155km. If I tow my 4.2m tinny around the usage gets worse too, and averages around 13 - 15L/100. The car gets serviced religiously - just wondering if there's anything I can do to improve the economy, as this rate I'm too afraid of putting any mods on the car as it'll be more thirsty that what a lot of you guys are experiencing. Bit frustrated. Any help would be great, cheers.
