Title: Crazy fuel consumption on my GTI
Post by: Black9 on 07 October 2011, 19:07
Hoping someone can help, from £20 of shell VPower I'm lucky to get 60 miles. This is less than I got from my old Type R when driven hard. Driving home today from work which is around 5.5miles. I drove under 3.5K RPM all the way with no hard acceleration and according to the trip computer I got 19.1MPG..... How can this be right?

The cars stock and fully serviced up to date by VW!

Got no idea what's going on and VPower costing over £1.40 a litre it ain't cheap :sad:

Is this town driving?
around town i would get 20-25mpg, especially if it is short journey's of short duration.
On a long haul, i can get 35mpg easily.
If you want economy around town, maybe get a small diesel car ;-)

Yes it's town driving but under 20mpg is ridiculous considering I'm driving like a granny, if I give it some hard acceleration it will easily drop below the 15mpg Mark which can't be right? Any other GTI owner I've spoke to says they get around 30mpg town driving :huh:

It's pretty obvious tho even around town I shouldn't be getting such bad mpg

I wouldn't get near 30 mpg at 20 miles an hour so I don't know who has told you this and I wouldn't reach 3500 rpm either at that speed.

Your mpg sounds correct.... Short journeys fella, you will not see a return above 20mpg if your doing such short journeys.

Remember your mpg on your dashboard starts at around 4-5 mpg from starting your journey, and only starts climbing slowly the longer your trip is.. :wink:

I do 20 miles to work and back each day. With a couple of longer journeys circa 50 to 70 miles on weekdays. Plus perhaps one 40 mile journey and several 3 or 4 mile journeys at the weekend. I do approx 800 miles a month. My average mpg is 30.

To be fair I do drive steady on the motorway, but otherwise I do enjoy a bit of pedal to metal action nearly every day!

Sounds about right, whoever told you they managed 30mpg driving a GTI round town is probably named Pinnochio.  If you are only ever making short journeys then if I was you I wouldn't waste the money on V-Power, putting the best fuel in the car and then using it around town is just pointless.

15 mike trip to work and I average 39mpg - mix of 50mph lanes and about a mile of queuing traffic. Average around 34-35 in total according to the car trip anyway.

Phew, appreciate the replies. Thought there was something seriously wrong with my car. But I still find 19mpg poor for a 5.5mile journey of granny driving :rolleyes:

It's force of habit for me to use VPower, don't mind paying that bit extra. Last time I used normal pump 95 the engine felt a bit flat...

Crazy tho how some people claim they get almost 100 miles for £20!?

You could easily get 100 miles on twenty quids worth of fuel, travelling at a steady speed of about 60. :smiley:  But it wouldn't be much fun.  Petrol seems to have dropped a bit in price recently round my way.

Personally i pay little attention to the trip computer over short journeys as it acts more like a random number generator for me !

I do mostly short trips (under 20 miles around town and generally drive it with a lead foot) and working it out from a full tank I average about 30mpg so your 20 does seem low.

Can I buy your engine in that case. :grin:

I've had a lot of mixed reviews on how much mpg i should be getting. Bearing in mind the 20mpg I get is town driving only which is a lot of stop/start. Going to fill her up today and see what sort of mpg I get. Is best way to do this is keep a reading of how many litres I put in, how Many miles I get to a full tank and work it out from there?

Yes that is the best way to get a true idea of what you are getting.

This is a good site for working out your MPG - input litres used/ miles driven/ etc and it gives you your mpg - http://www.torquecars.com/tools/uk-mpg-calculator.php

My trip computer shows average 26mpg on my 7 mile commute to work - haven't filled it up and calculated properly yet as i've only had the car 2 weeks

Your doing well at 26mpg. Is the route u take in town or longer and less stop/starts?

I've found the car's fuel computer to be very accurate when I've worked out miles/fuel used manually.

You should try taking the car on a decent run (30 miles+) to see if you can get over 30mpg.

Under 20 mpg does sound poor unless you are stationary for long periods. I can get 25+ on a shortish town run.

Your MPG is correct  :wink:

Sounds about right tbh. Short town journeys are terrible for fuel economy, even in my 1.4.

i get 24mpg town driving/short journeys  and i get 35mpg on a run up the motorway ... moderate driving in both cases. Put the hammer down and its down to 19mpg .....my car is mapped and i run it on v-power which i find gives a better mpg than regular 95

you sure you havent got a hole in your tank  :grin: lol

Alright I have something to add here.
I won't be bothered convert my numbers to your odd ways, but the meaning should be clear.  :tongue:

It seems to me Idling and going in 1. gear consumes alot of petrol compared to going in 2.
If I'm driving in heavy traffic and letting the engine idle in 1. but still pulling me gently along i get about 7 KM/L. When I manage 2 put it in 2. the computer shows 10KM/L when idling along.

If I have to stop completely for a while my fuel economy drops dramatically. My average is affected by a few minutes of idling at the traffic lights even if the journey is 15KM long.
