132kw fuel economy

[IN2VWS]

Hi guys,

I thought it would be interesting to see who can get the best fuel economy out of their 132kw TDI, using the readings from the MFD.
Please list the ∅ l/100km, ∅ speed and time travelled from a minimum distance of 500km. That is, you can't list the economy from a short trip of 50km.

Have a look over at this thread an consider signing up to Fuelly and sharing your ongoing fuel consumption with the world

last tank. 7.8l/100. 132kw. nailing it about town and a trip down south. filled up with 2 bars of the last quarter remaining, only got 69l in think.

Hmmmm.... tried the fuelly website.
The Fuelly website says my economy is 8.3l/100km, but my MFD tells me: 8.0l/100km, Total trip = 857km, average speed = 45km/h, total time = 19h 09m.
I tend to trust the MFD reading rather than fuelly.
Fuelly's accuracy is reliant on how much fuel you put in your tank, and, I suspect the temperature when you fill up also affects how much fuel you can put in your tank. This morning when I filled up, it was 4°C. Another factor is how much the fuel is foaming up in your tank while filling.

Not just by the temperature, these humans operated pumps could be quite inaccurate I have to say.

That's fantastic fuel economy regardles. However you had better last week.

Was reading something years ago in regards to filling up.

Was said it was best to fill up in the evening or early morning (IE: When it's cooler) & to not depress the filler all the way... Best to use only 50% (Which can make your fill up a great deal longer when your not at a high flow diesel pump).

Unsure how true it is of course but it does make sense.

[Transporter]

I will try it, especially not to depress the trigger on the nozzle and 50% volume is probably truth since I've noticed when I filled the tank 1/2 full I had a better fuel economy.

Thanks for the tips.

FYI, Those is Sydney.

Vortex Diesel on the Northern Beaches is 1.59.9 still. (and even 1.60.9)
Vortex Diesel at the Caltex in North Ryde. 1.50.9!!

That is a decent saving of $7-$8 on a full tank! I can't believe the rip off prices that are about.

I don't think temp has a great deal to do with it, the pumps are well out of whack tho, I once put 82l into an 80l tank that wasn't empty!! go figure.

I think the 80L figure on the tank is pretty nominal. I've put up to 84 in mine (and I still drove into the servo), but it seems to get a little more every time I rip off a fuel tank strap going off-road (a problem I hope I've cured now). There was also a post a while ago about how to get an extra couple of litres in the filler pipe at the end of your fill (something to do with dodging the venting). Never quite worked out how, but maybe I'm doing it unknowingly.

The code on the plastic fuel tank has an 85 listed in the number, so I presume that it is an 85L tank.
I also have put 84.3 litres after the range on the MFD suddenly dropped down to displaying 25km, and I had about 55km to go to the nearest servo!
