Official Fuel Economy Thread (formerly Highway economy).

I can sit on 110kmh (Speedo-indicated) up the Bruce Hwy and come back with 5.5l/100km on the Hwy run from Brissy to Noosa, but that's a TDi, and just cruising, not gunning it past anyone (too old for that!)

With my 125, and 95% city driving to and from work, I'm averaging pretty stock standard 10L/100km (30,000km). Can get down to around low to mid 8s on the highway but I generally do 120km/hr (speedo) in the 110 zones.

I'm still dumbfounded as to how team v averages such low fuel economy with such modifications. I'd be up around the sharki figures if my Tig was modded the same as team v's!!!

APR is great for power but i rearely get to utilise it for it's potential.
Because it doesn't get pushed very often the apr actually ends up giving a good fuel economy figure.

my experience as well, and the fuel economy is helped in part because torque below 2500rpm is also improved a lot with the APR mod. That makes it easier to drive at lower revs and lug around in higher gears, which everything else being equal will 'almost' always, improve fuel economy.

Same setup as Roscoe, although a 2011 silver leaf TDI, I travel the Brisvegas corridor but from Buderim way. Trying to break 1000km with this car but always get tantalisingly close and miss it.Has anyone got over 1000km on a tank from a TDI? I have just done 12000km

Hi all, With a 103TDI I typically have a mix of Freeway and city ( F3. Pacific Hwy for those who know sydney), and average 5.9-6.0 on that type of trip. Best I have seen is a trip 3 weeks ago Bathurst to C Coast, so through Bell Line of Road, Blacktown Rd, M7, M2 Pennent Hills Road and F3, it was middle of the day so light traffic and averaged 4.9, which is the first time I have averaged below 5. At this stage I suspect the MFD is reasonably close, as I have taken it down to empty and the trip meter was saying I had 30 kms left.

Dargan...............I have routinely got over the 1,000 km per tank, the trip above from from Bathurst was suggesting I would get ~1200, but I prefer to have some in the tank than run out on a Motorway. Good luck breaking the 1,000 k mark, mine has 10,000 km on the clock.

I've not yet taken delivery of my 118 TSI manual so I read this with interest.
Many things are relative; trading down from a Turbo Territory and 19l/100ks I shall be ecstatic with anything sub 10!
One question I have is about fuel . I see little mention of grade or brand in this thread.
I see some discrepancies between the brochures, Wheels magazine and the dealers. Is 98 RON THE ONLY APPROVED fuel grade?
And what are the feelings on brands?
Any info gratefully received.

Is 98 RON THE ONLY APPROVED fuel grade?
And what are the feelings on brands?

With 95 RON, the car is slightly rougher and sluggish taking off. I can feel the difference but my wife cannot.

Of all the brands I have tried, BP ultimate offers a slight better milage than Vortex98 and VPower (Hwy: 7.8L vs 8.1L vs 8.3L/100km). Suppose you have a fuel docket for Shell/Caltex, the final cost difference between brands may be negligiable. Although BP probably cost me a bit more, but I hate queueing up for the other two.

Give every brand a try, your driving style may get you a different result.

[whiskywallah]

Thanks for the info. Really looking forward to delivery in 11 days. With 2 identical cars it will be interesting to compare fuels and drivers

[iamthestig]

z1000 - Is that on a 132 or 155 ?

[MGV]

Though i mainly use BP ultimate also, have not noted any real difference to the Shell VPower. Certainly not 0.5 l/100k's!
Interesting to note my long term average has just reset again (yet another 100 hours clocked up!) & my city driving average still around the 9.2 mark. Heaps better than 19, hey whisky?!!

132. All highway figures are obtained from regular Waterfall to Gong drives.

I do such test to prove that Shell is less economical in the daily city commute.

[Dargan]

Am now close to 27000km for an April 2011 TDI and am getting over 1000km per tank. Even an indicated 1150km at one stage. Very economical cruiser for highway running.

HI All

Recently picked up my 118 tsi and driven it about 1500km. Im a little concerned about fuel economy. Ive getting on average about
11.2lt/100km, which is a far cry from the state 6.9lt/100km. I do mainly suburban driving (NOT city grid lock driving), and am averaging about 550km per tank. Im a little dissapointed considering its a 1.4 litre and 2 whel drive and that I am a conservative type of driver. Is this going to improve with more driving?

[masev]

Considering the very low km you've travelled, it will DEFINITELY improve as the km's roll on. I was averaging about 300km on a tank from my Golf R in the first 3000km and am now averaging around 550km (now @ 16,000km).
