Fuel Consumption - How's THAT going ?

[Ralfi]

Ahh thanks. I asked because iirc, the engine in the Polo GTI needed to be run in after a certain number of km's had been reached.

Different engines, different characteristics/demands eh?

No, they are all engines and can be treated the same.

I'm not sure you have an understanding of what the term "run-in" means. You are running-in or bedding-in the engine (and all the driveline, brakes, suspension, etc) from the first turn of the key at the factory.

You can run them in gently like my aged father does & have a slow engine that drinks fuel like a sailor on shore leave.

You can run them in briskly but gently and they will spin nicely, get good fuel economy & last a long time.

You can thrash the bollocks off them and they will do all of the above & maybe not last quite as long.

I'm a middle-ground guy.

Run in is most important in the first few ks. Vary load and speed and you should be right. I'm not trying for economy in any way, just commenting on the figures I get. I took it for a drive in the hills and used the firm run in method. Car gets a proper spanking every now and then also. All my vehicles get that and I haven't had a bad engine yet.

Appreciate all the info, Brad.

I'm not an enthusiast when it comes to cars (clearly), but interested none the less.

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)

I find driving into a head wind or driving in rain makes a bigger difference than air con to the economy. I regularly get around mid to upper 4's with highway driving sitting around an indicated 105 (because of the inaccurate speedo) A trip to Sydney and back with air con running all the time gave 4.5 one way and 4.6 the other. The MFD economy readout is usually around 0.2 optimistic. After 73,000km my long term MFD readout averages are always 5.3L/100km

This is my first VW and have been enjoying my 6 week old MK7 GTI PP. Its used primarily for commuting to work each day. I feel that I have been running it in "briskly" with the odd squirt of the pedal occasionally but have noticed a drop in the range each time I have been refuelling (all 98RON). The second refill included a round trip from Melb to Bendigo for work and I probably got close to 600km from that refill.
Avg. consumption depending on traffic started around 8.8l/100km and now edging up to 11l/100km travelling the same route to/from office. The large drop in range is not something I was expecting.
1st tank 560km
2nd refill 560km
3rd refill 520km
4th refill 480km
5th refill 450km

Should I be concerned and take it back to dealer and insist a check up or let it run in longer?

[Dam355]

My MK7 GTI will get around 750km on a long run including overtaking, some spirited driving as it was through wine country in the southwest of WA. Around the city it will get around 600km +

[GTR27]

What average speed does each tank have? I find that the average speed a better indicator than outright tank range. If your average is very low <30 then over 500 is OK. If its 60-70+ then that sounds like your having issues

[brad]

6weeks / 3000km. Engine isn't anywhere near run-in. Give it another 2000km.

[eldubyas]

Appreciate the feedback. I will check out my avg speed and keep on tracking while it runs in for longer.

I'd like to think I'm doing the 1.4 TSI proud Keep in mind that 650km of that was on normal mode, I only just put eco mode on when I took the photo. I ended up getting a total of 755km out of that tank with 10km to empty on the trip computer.
The car in total has done 2400~km.
TSI for the win

[Mountainman]

Heh I have a 2013 90 TSI and I notice that they range display position has been changed on later models. mine has it in the first line of the display on the right. And if I had a range of 75km like in the above photo my car would be closer to the petrol bowser.

I am driving a 2015 Octavia petrol RS wagon DSG as my daily commute, 25km each way, average speed 30-40 km/h sometimes as low as 20(Sydney traffic), car has done almost 2000kms.

I am getting around 10L/100km on average, however I am still running in the engine, so I rev the engine to 5k even 6k from time to time.

Got down to around 8.5L/100km one morning when it was raining where I used D almost 90% of the time.

Just back from a reasonably long trip. 2014 TDI wagon, 18000 odd on the clock now, heavily loaded for a 600km each way trip. 5.0 l/100km on the way up overall, 6.0 l/100 km on the way back in foul weather, sitting on 114 km/hr indicated on the cruise control both ways pretty much. Can't complain, tho the 6 was a little higher than expected.

I had the Yeti 103 TDI before the Octavia RS petrol, I found Diesel does better in town than freeway run, went down to southern coast for holiday with 4 adults and a baby onboard, we average around 6.7/100, however on my daily commute I was down to 5.6 or so without even trying.
