Fuel Consumption - How's THAT going ?

[Brendan_A]

Refueled the GTI tonight. 7.7L/100km, 631km to fuel light. 280km was highway driving rest was town driving.

Thank You Dutch77,
I am switching off my "stop & start" manually - every time.

IIRC that can be fixed on VCDS, failing that there was a. Kufatec dongle that achieved the result as well.

I have deliberately activated it in long waits in peak hour but otherwise not.

I'm getting around 6l/100 since refuel. Bumped up my tyre pressures to 40psi, I like it since I can feel the road a bit better through the wheel! Anyone know what the safest max is?

It will be on the sidewall of the tyre.

Beyond 40 you are getting into the realm of diminishing returns

Yeah I've decided it's not worth it, dropped down to 34, much more comfort, really a negligible loss of economy..

Try 38F/36R. That will be a happy compromise.

Cheers I'll give it a whirl tomorrow and let you know how it goes

Just drove 130km back from work in Toowoomba to the centre of Brisbane. The usual 4.2L/100km. Makes me wonder what the diesel would do?

[GTR27]

I doubt the 2L diesel would be any better......on a flat, the engine would be using barely any power/torque, so the smaller the engine, the better the economy should be (even taking into account more energy stored per L in diesel). If it was a 1.6L diesel (which we dont sell in OZ IIRC in the golfs) then you might be able to better it.

Is that figure from when you roll down the range and through Withcott?

[Mountainman]

From leaving Ground Up coffee in Searles Walk between Ruthven and Duggan Streets (I don't work there - just enjoy the best flat whites ever made). At Withcott it is usually showing around 2.7L/100km average and that gradually climbs to around 4 by the Plainlands pub. The 4.2 indicated average is usually about 4.4 true. The reverse trip is nearly always 5 indicated. That usual crawl up the range at 40 in 3rd or on one occasion at about 10 in 1st is doing my head in. I sometimes go around by the Blanchview Rd - more fun too.

[Brendan_A]

The up section is crap! The run down is not bad now. Very impressive figures anyway.

Figured this doesn't require a new thread. In your experience, at what speed do you get the best fuel economy? Probably best to list engine and transmission.

1,500kms into mine and it's 9.9l/100km on city driving. Struggles to even get close to 500km before the fuel light comes on. Drives in Comfort or Normal mode. Wonder what others are getting as the car gets run-in further..

top gear, around 2000rpm. Probably 80-90kmh. It desn't sound very fast but surprisingly that's about the speed most city motorways flow at.

You shouldn't be trying for economy at such low mileage. The engine will still be bedding-in right through to 15,000km. You'll be about 90% there at 5,000km

On my 90 TSI manual I reckon it is around 70km/h in 6th at around 1500rpm, just after it's reached peak torque. It would bring in an average well below 4L/100km (even 3.5 maybe) but where would you have the patience to try it? It would certainly piss off most other road users.
