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

[Corey_R]

lol... averaging 8.4L/100km on a R is impressive. Too impressive. I'd go as far as to say that you're not driving it "properly"
Try harder! hehe

I'm averaging ~11.2L/100km on my R, and several of the R boys are averaging more. But then, it's a hundred odd kg more than the GTI, has AWD, and has an engine which is not "optimised" for fuel efficiency combined with a turbo which doesn't get "on boost" until 3,000rpm odd which is DEFINITELY out of the "fuel efficient realms" !

Most of that was on running it in, keeping the revs relatively low, no hard acceleration. I’m expecting it to go down a bit, but it will be interesting to see what I get. Most of my driving is on pretty open and flowing roads rather than stop start traffic. When I was driving my S3 in the city a lot and engaging in semi-frequent traffic light grand prix I was averaging around 14.5l/100 km. I’m thinking about the 10.5-11 for this one.

But it’s not something that worries me that much to be honest.

...consuming 14L/100km on average. I literally can see the fuel indicator moving!

Stop worrying and just enjoy mate.

I am having lots of fun and can't be bothered about the FC now. I am loving 3rd and 4th gear. Mainly use it manual, shift it across to D when in lots of traffic. Will be taking a drive out of city on the weekend, woohoo!

My 1,100kms R managed a highly respectable 9.0L/100km (averaged) read out from the MFD recently....never thought i'd see that!!!! It's always been bouncing between 12 and 15L/100km!

I've also managed to run my R on 1 tank of fuel for 5 weeks compared to burning 1 tank in 2 weeks when I first got it =)

My driving style now has eliminated the need to use 2nd and 4th gear.

From standstill I switch from 1st to 3rd to 5th and 6th. 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.

[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.

[prise]

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.
