...my Prado definitely not stock...

Looks stock to me.










Nah just joking, looks tough. Good build Matt. Not sure what this washing thing is though, hopefully it won't catch on.

If you work it out as u average 8ltrs/100kms (12.5kms/ltr) and say you can easily use 140ltrs of the 150ltr tank (leaving 10ltrs spare) that means 12.5 x 140 = 1750kms out of a tank full. Is this the sort of range you are getting?

If u work it out on your figures u showed below then 13kms/ltr (7.7ltrs/100kms) x 136ltrs = 1766kms out of your tank.... is this what u got?

That's pretty amazing sort of figures I reckon as we don't get any where near that at all. We avg 12.4ltrs/100kms (city driving).

My trip computer shows 7.6 - 7.7 most of the time based on probably 50/50 town/country. Fuel consumption from my sat nav calculates slightly more at around 7.9/100k. I would be really depressed if the consumption went into double figures.

I'm also interested in how accurate you all think the range display is. The car is meant to have a tank of 150L, yet I can drive for almost 100k with the range reading zero and yet I have never put more than about 136L in the tank. Is the fuel reserve really that much? I haven't been brave enough yet to run more than 100k with the range reading zero.

Yes I get about 1720-1750 per tank (well 136L), which leads me to trust the sat nav more than the car for the fuel consumption. I guess my fuel economy is a result of spending many years driving in Europe with the rip off fuel prices and learning to get the absolute best economy possible. I rarely accelerate hard and rarely do more than a gentle dab of the brakes, usually when I've botched up my planning. When I picked the car up (it is second hand) it had about half a tank of diesel and was showing about 14L/100k on the after refuel screen. If I fill up just before a round trip to Sydney I usually have it reading 6.8-6.9 by the time I get home again.

I've found that the trip computer tells porky pies as on the last few tanks it's indicated consumption averaging in the 9s . On one fillup I'd actually done 1100k's and put 120 litres in , the next was 1200k's and 130 litres so how does that average in the 9s ?
Would the Scangauge be more accurate ?

Correct..... mine does the same thing. I find it's usually out by about .5 to 1ltrs/100kms depending on the type of driving that u do

Resetting the trip computer as soon as you have filled up also helps. Not waiting til the top of the big hill on the way home. :-D

Having said that, it's still out by about 1L/100km for me generally.

Having tried to use the scangauge for this function, not sure.

You would think that the fuel management system would know precisely how much fuel was being used and that the Toyota display would be able to use this. Maybe it does and it is the distance measurement that is out?

The scangauge needs to be calibrated, i.e. you need to tell it how much fuel you have put into the tank while it tells you how much fuel it thinks has been taken out of the tank.

You do this at every fill, I did it for quite a few cycles but it never seemed to get it right. Sure it got close but never correct. There is one major problem with this "calibration" procedure, you have to fill the tank to the same level every time. Given the different pumps, slope of vehicle, degree of foaming, patience to try and get the last drop in and possibly others there is an unquantified variable here.

The calibration factor ended up around 40%.

One thing the scangauge does do is give an accurate speed and possibly distance(?) I suspect it reads the speed info from the GPS on the satnav fitted to the Altitude. I suspect other models with factory satnav will be similar. The scan gauge speed indication agrees with other GPS units I have in the car at various times. I suspect the speedo reads the speed from the drivetrain.

Hey Prone.....

I had always thought that the speedo had been designed to have a small error to help prevent people from speeding.... Well that's what I've found in all the cars that I've had. The SGII unit in ours reads accurately where the speedo was always out a bit and we don't have a inbuilt satnat in ours. I believe it just pulls the data from the computer.....

Re: SGII - I just filled our tank up today and b4 filling it the SGII indicated 108ltrs. I actually put 109ltrs in and that's filling to the absolute top where u can physically see the fuel at the top of the filler.... this is what I do all the time and I find if I use BP Ultimate Diesel, there's less frothing and therefore less time in filling to the top. When I use Shell/Caltex Diesel I find they froth too much and trying to fill it to the absolute top becomes a PITA, but at least with the SGII, I have an idea as to how much I need to put in.

Our SGII is set on adjustment of 45% and after today, it now sitting on 46% which should be pretty accurate now.... but this will change again when we are loaded up and the back is sitting down a bit, it's a bit of a balancing act. Still, I've found the SGII very helpful when touring as to distance and fuel left and when/if I need to fill up....

cheers....

1st post

Just bought a 2010 GXL D4D Auto with 71k on it last week. First tank is reporting 11.1 on the trip computer.

The vehicle has ST MAXX tyres, which I'm sure won't help, and I think I need to learn to drive the auto a little more gently

Re: Trip computer being out, I found that the one in my Navara was out in city driving, and I believe it was because it didn't measure any usage while you were idling. So if you started the vehcile up, drove all the way through the tank until it was empty without stopping, it was accurate, but if (like most people) you stop and start in traffic, at home etc. then it will skew because of that.

Last time I was at the bowser I got curious and actually checked my consumption. I got 1460kms from 128ltrs at the refill which works out to be roughly 8.8L/100km. Mostly around town driving and a couple of short h/way stints (about 80kms each). My car is fairly stock weight & tyre wise & has had the exhaust done, Also I've been trying that "chemtech diesel power" for about 3 tanks now.

10.1/100k's

[rob_macca67 Avid PP Poster! Find all posts View Profile Close rob_macca67]

We just got back a 8000km outback trip... The car was packed fully and was shaped a bit like a brick when it came to wind resistance.... the avg economy was 13.2ltrs/100kms. Not real good but good for where we went and the load we were carrying

Fully loaded figures

Those figures you return actually look like real world figures. Over the yaers I have seen and heard many 'wonderful' accounts of fuel economy figures. You seem to be one of the few to say what you are actually achieving with a full load and touring gear fitted.

I have had a 2010 Prado and a 2012 one, they both come out at around 11 l/100km. The trip computer lies. Typically I end up doing around 1200km to 1250km and use 128-135 l of fuel. I drive it as hard as I can without getting a ticket.

it does get better when taking it easy, except I only last about half a tank.

Picked up my new kakadu week before last and fuel economy out of dealership was sitting on 13.4L now after doing a little of 700km it's on 13.7L ? I have been a little heavy on the.accelerator at times but even so would still have expected a drop? Is this normal ? It is a Diesel.
