Standard test figures are intended as a comparison between engines based on each doing the same cycle. They were never intended to represent what you would actually achieve.
Real life driving will produce different figures for each driver based on conditions locally. These too can be collected and used to produce actual consumption results.
So as a comparison both figures here are correct in their own way.
Yes, the standard test figures are the only way of comparing different vehicles, but the real life figures the only way of assessing what is the likely real life consumption .Quote:

For example. If you compare joel's Yeti to my Scout (both vehicles share a lot of drivetrain and chassis components, but I have the earlier PD engine and manual box, his is CR and auto).
His Yeti has a claimed combined figure of 6.0 litres/100km.
My Scout has a claimed combined figure of 6.4 litres/100km.
So driven in the same manner in the same places you'd expect the Yeti to do better.
But I've got an eco remap in my scout and my driving is more open road. So My average is between 6.5 and 7 litres/100km and his (from his fuelly records) is 7.6.
In defense of my Yeti's poor consumption. I drive pretty hard, I always seem to be accelerating to 80km/h from stop lights and Diesel in Darwin is pretty rubbish.Quote:

I find it funny when people like BP or Shell or whatever over the other. All the franchises are also owned by Ausfuel so it doesnt matter eitherway.
On the open road loaded up with the family of 4 it sits around 6.2L/100km which ends up just shy of 1000km per tank. The best I have got was just myself and the oldman going from Bathurst to Sydney, over the Blue Mountains. It got down to 4.5L/100km. Around Darwin it's pretty bad but I rarely see it over 9L/100km.
I drove it to Darwin just after we moved up here in April last year. I towed a trailer with all the stuff that the removalist wouldn't take (like the dogs). I went across a weightbridge and I think we came in a 2600kg? 2800kg? or something and we averaged 8.0L/100km for the trip of almost 4000km. I thought that was pretty good considering we were still wrapping up road trains at 140km/h (or a bit more).
Happy Days.
That's not poor consumption for a tdi Yeti, getting below 5 litres/100km is exceptional. But it does appear the 6sp DSG versions use up to a litre more every 100km than the manuals.Quote:

I used a scan-gauge to keep track of whole tank consumption and calibrated that over several fill-ups. Then I used VCDS to calibrate the trip computer so it matches the scan-gauge read-out.
Ive got a new discovery 4 and find its about a litre or 2 out with its read out can i fix that with a scan gauge or something like that do you know?Quote:

Yep. Maxidot is out by about 0.5L/100km but I just use Fuelly to calculate my consumption.Quote:

I don't know how much of my stuff you can see in fuelly but if you look at the graph, you'll see a few tanks in quick succession in April and October 2013. That was when I drove to Darwin and then a trip from Darwin to Bathurst and back.
I wish there was someone close to me with VCDS. I got the usual changes done like fog light for come and go light and needle sweep while I was in Canberra but I can't justify the cost to buy VCDS to just change the fuel figure.
Happy Days
Thanks mate i didn't know which one was the correct one to get, but thanks for that i might look into it!!Quote:
