  • Mk4 GTI fuel consumption??



    Does this seem high? Taking off at lights (yes it's cold) not as bad when warm but still not great- I understand it's turbo etc but driving it sensibly still
    Seems pretty high? Has gotten up to 70L/100km on just taking off from the lights sensibly haha

    A litre in an hour isn't much. How far do you get out of a tank? I would expect over 500km easily. Those are instantaneous figures not averages.

      When its reads litres per hour you are not moving. 1 to 1.5 per hour is normal idle.
      When driving it will change to litres per 100KM.
      On warm up cycle expect something in the 20s. Moving off the lights mid 30s. Cruising in 4th gear 7-10 litres/100km.

        its a video. Idle with ac on is around the 1.4 mark or so and 0.8 roughly with ac off which obviously seems fine.i just got a bit suprised on a normal take off how high it goes up

          Ok saw nothing to indicate a video
          The most I have seen in my Jetta 2.0 (golf has no display) is 48litres/100km, nailing it up hill. The numbers jump around all over the place. You will see 0.00 when going down hill too.

          Start taking note of your odometer each time you fill up, work on the overall consumption when you fill up.
          Use fuelly.com to track things if you like.
          In that car city driving, anything under 10 litres/100km is OK.

              take a look at www.fuelly.com it is an international website but you can find cars of all makes and models for comparison and you can use it to log your own usage too, I have found it quite handy when car shopping for real world figures

                Around town driving normally you should get 550-570 and highway should be able to do 700km-750km.

                  I used to get roughly 550-600 kms per tank, I don't even bother counting now but this 100oct stuff has got my attention. Where do you get it from?

                    i usually wouldn't bother paying any attention whatsoever to fuel consumption figures as i couldn't give a crap, the fact that the bloody L/100 is right in front of my eyes and constantly changing its just too hard to ignore haha i wish i could switch it off. I just want to know if somethings wrong , ill have a look at this fuelly site.

                    United servos you get 100 octane and e85 !

                      Shell used to have a 100RON product called Optimax Extreme, then it changed name to V-Power Racing or some such. It had 5% ethanol. Only a few servos had it, Coronation Drive had it and was my local for many years.

                      The United and other independents have a 100RON, they have rammed in 10% ethanol, which pushes the RON up but lowers fuel effifiency.

                        Revival,sooo did some measuring and got 90km/10L (180km/20L) bit higher than i was hoping but i guess i do 50km a day in an hour and a half of driving - stop/start with air con on not thrashing it but driving it how a gti should be driven-does this sound about right? might change my fuel filter,temp sensor and spark plugs just cause..

                          We have already stated what you should be getting. Set your trip computer and run the tank til the low fuel light comes on.... This I think means 5L left. Add an assumed 50km on to you trip and then tell us your figures.

                            Waste of money on parts if there's no proven defect.

                            The fuel filter was probably never changed but I have only seen them make a difference on high output cars.
                            The temp sensor can be checked with VCDS, make sure it goes up from cold, with the gauge.
                            Plugs I doubt that will do anything either, unless you have a misfire when giving it a bootful.

                            The numbers you have indicated would take you about 500km on a tank, which is 10l/100 ish. Through traffic, I don't see you doing better tbh.

                            An indication of how good it is on fuel on the highway, would tell you much more about how well it is running.

                              its about to hit 160 so its up for a service.Fuel Filter has been changed several times,need to double check service book but i know it hasnt had new fuel filter or plugs in some time,changing these parts can only be beneficial. i wanted to know a rough figure on what i should be expecting per100km as i thought it was a bit higher than it should be but my question has been answered.

                              Referring to the original post-how high up the L/per hour would go up on take off (up to 70L/hr on a hill start :S) didnt seem right??
