Fuel Consumption - How's THAT going ?

[GTI PP carbon]

High Fuel Consumption MY15 GTI PP

We have recently replaced our Mk6 GTI DSG with a new MY 15 GTI performance, DSG.
I am wanting to know if any other owners are experiencing a high fuel consumption with their GTI.

I know these are performance vehicles and you don't buy them to get great fuel consumption however I am getting nowhere near what we used to get with the Mk6.

The car has done about 2000ks and the last 2 fills have returned 11.6 and 11.75 L/100, all city driving. No thrashing, just normal city acceleration.

We did a highway gentle run-in when we picked up the car of around 650ks and refilled with a return of 7.7L/100.

The Mk6 returned around 8-9 L/100 consistently for all city driving.


Are these figures pretty normal? No where near the 6.6 L/100 combined quoted by VW.

Don't be frightened to drive it hard. If that's your first 3 tankfuls then the engine is still going to be very tight. The consumption will improve as the engine gets the miles on.

As Gavin said, consumption on my R has decreased over time.

I get around 550 - 600 km around town and 750km on long trips in my MK7 GTI.

[brad]

fuel economy will improve dramatically after 5000km but that still sounds kinda lousy...

Assume you are using 98ron?


BTW: I'd be inclined to get some boost happening & get some pressure behind the rings ASAP or it will be tight forever

[Dutch77]

I'm around 10% lower on my Mk7 compared to my Mk6 across the board - but no, you won't be matching the 6.6 quoted by VW.

I still get better economy driving it without watching the economy than my in-laws get in their Mazda 3 though - and I know which is more fun.

All car companies have secret ways to come up with "official" fuel figures. At least VW are reasonably close to claimed. My now departed Merc A250 couldn't get within 25% to 30% of their claims. All of my VW's definitely improved over time. You could try the Eco mode in town but then the engine and gearbox loses any responsiveness and character and isn't that why we buy a GTI in the first place?

That sounds high, even for a tight engine. Give it another 1000-2000km and if it's not into the 8s for normal urban driving then there's something funny going on

Also run ins shouldn't be gentle. Give it some stick asap

There's a good thread in the Octavia section that explains the fuel consumption test. Basically, a turbo almost never gets on boost (IIRC, you're allowed 41 seconds to get to 100kph) & can achieve some amazing test figures. I assume the 41seconds was so that the Wartburgs & Trabants could pass the test.

I believe they are looking at revising some aspects of the test to make it more in line with how people really drive.

Going very nicely in my Diesel

I have found (and Gerrycan has also mentioned iirc) that ac makes a fairly large difference to economy in a 1.4 manual. Almost 1l/100 difference. I can drive in 60 zones around town (non peak) in the mid 5s, but ac bumps that up to low to mid 6s. Stop start bumper to bumper is low 7s now. Highway with ac is high 5s, no ac I reckon I could nearly get high 4s. Engine has loosened up nicely, about 3.5k on the clock and keeps getting better each tank. Gauge seems quite accurate (both fuel gauge and trip computer)

[Baz 55]

Comfortline 90kw 200nm petrol
Usually drive in Eco Mode (DSG)
2000k on the clock.
Long Term 5.8l per 100km
Last Tank 5.5l per 100km
Driving - city / outer urban mix.
Fuel 95 Ron (just found out I should be using 98 Ron (oops) Next tank

Update - 20,000km on clock - same type of driving.
Seems to be roughly 5.3 on average.
Driving mostly in Eco mode and have become an expert on coasting !! lol

[JVdPoel]

Comfortline 1.2L - 105bhp - TSI DSG
Mostly used for commute to work which is 50 - 70 - 90 km/h roads
on cruise control, lots of turning on small roads (50km's per day)
6.4L / 100km on the long term (got 2000km on the car now)

Always use the eco mode of the DSG and disable start/stop as soon as I leave home.

Recommend running it in straight away, or after the first 1000km?

straight away. You need to bed the rings in while the cross hatching on the bore is still "sharp".

I'm not saying thrash the engine but for most people run-in has to be more vigorous than what their normal driving will be down the track. It's a really hard head space to get yourself in. My wife just got a new Honda & she can't get her head around it (partly because she is extremely stubborn and doesn't really give a crap about cars).

I can't believe the number of people in this thread that use cruise control, eco mode, "D" mode and aim for fuel economy in the first 3000km. You are just setting yourself up to have a slow, tight, thirsty engine that will probably use more oil than it should.
