The MK6 Fuel Consumption (Most / Least per Tank) Thread

[Corey_R]

I used to do that on the Polo GTI all the time... 1st, 3rd, 5th (there was no 6th). You don't need to redline it though... changing at 3,500 would bring it into ~1500rpm (from memory) which is already on boost in a Stage 1 Polo GTI!

In fact, Volkswagen actually recommend skipping gears if traffic and road conditions allow (I can't remember whether it's in the owners manual, or the "driving economically" hand out).

6.7L/100 from Melbourne to Sydney along the Hume, including a good half hour or more of slowish to stopping traffic on the Western Ring Road in Melbourne due to road works - not to mention all those pesky other drivers getting in the way. Cruise control all the way (when possible).

That's 0.2L/100 better then my MkV on the same drive last year (40,000+km difference in total car travel) but road works weren't a problem and there were fewer other delays. So good run vs bad run and still better.

Better than 6.3 L/100km average since new with a mix of city and highway running. Best on a single tank has been 5.7L/100km. The trip computer seems to be pretty accurate. I've compared the trip computer value vs the value calculated from fuel purchased & distance travelled, and the two were within 1.5% of each other averaged over 15,000 km of driving.

Since new I have averaged around 6.2 to 6.3l/100. Having fitted the Superchips ECU and 19 inch wheels at the same time, the figure went to around 7 to 7.5l/100. I immediately blamed the ECU upgrade for the increase, so returned the tune back to stock. Have run 3 tanks since with the same fuel and similar conditions. Guess what? No difference! The rolling resistance of the bigger wheels seems to have increased fuel consumption in the order of .5 or more l/100. Have just reinstalled the ECU tune so will confirm after a few tankfuls. Food for thought for those wishing to fit bigger wheels. BTW, the next test will be to refit the old 16inch rims with the ECU upgrade. Takes time as I only do a few hundred ks a week.

[Corey_R]

Yeah - it's not just the rolling resistance of the bigger wheels. What is the weight difference between the stock and new wheels. Rotational weight has the highest impact on performance than any other type of weight in the car (unsprung, sprung, etc). In the case of wheels, it's unsprung rotational weight - so it's the worst possible place to be putting on weight.

Not quite babying the car entirely though because I have 'accidentally' boosted to almost red-line on 4 occasions I hope I don't kill the engine.

don't worry about it, my last car was redlined 4 times by my friend with 140km on the clock when i took it up to his place, and after 101,000km of HARD driving it doesn't burn a single drop of oil nor have there been any engine issues. The same friend picked up his Alfa Giulietta a couple of months back and with about 200km on the odometer I added another 50km or so of wide open throttle and redline (partly as payback!), and neither of us were concerned.

The GTI I picked up 3 days ago is getting driven as it will for the rest of its life, as hard as it needs to be. I've tapped the redline about 6 times now in 500km and i don't think that's bad, it was done because I had to get the car moving fast for a particular driving situation. Plenty of WOT but usually shifting at 4000-4500.

Average fuel consumption for me at the moment is 8.7L, but this is majority peak hour freeway work, I think that's a pretty good average so far.

[shakespeare]

I think I might need lighter shoes or something! I've averaged about 13.5L/100 km since new, though most of this is city and the few times I've gone country I've thoroughly enjoyed the drive therefore fuel use was a little high!

Still, I didn't buy this for economy and is similar to my old MPS

btw the fuelly hasn't been updated for a while!

[Brian916]

According to the computer, I'm doing aroun 7.8l/100km but that's in Canberra to/from work, with little or no stopping, and gentle 80kmh zones. Makes good economy simple. Current fill is at 9, but that was filled up at peak hour, and I had to drive around a car park looking for a spot so I'm not counting this as 'normal'

[Prodigy]

Thought it was about time i checked my usage on the R and i'm pleased to say it is a respectable 10.4 L/100km.

[GTI Go Karter]

My mk6 GTI fuel consumption is down to 4.9l/100km , ok sorry my wife's fuel consumption is down to that and she runs between 4.9 and 5.2l/100km . but when i'm driving it jumps to 5.9 and 6.7l/100km . But in saying that i only get this low fuel consumption due to the modifications and overall the running gear is very different to standard vw gti .

[Brendan_A]

On our trip to the Gold Coast today the 118tsi averaged 5.2L/100km. Not bad, almost as good as our tdi Jetta.

Do tell? What changes have you made to improve the economy?

I'm at 9.2 now.

I spend most of my time on the open road.

Would a stage 1 tune lower fuel consumption?

[masev]

Apparently it does....
