Make the GTI drink less?

[marcnazer]

Some of you might of noticed a couple of threads by me lately looking to get a more efficient car as I've taken a new job which involves a lot of town driving.
I cant think of a new car I want at this stage which I like as much as the GTI for the money I have to spend.

So anyway, im in a Mk5 GTI DSG....round town im averaging between 23-25mpg. Is there anything I can do to improve this to get it upto...sayyy 30mpg?!
Remapping? Removal of the Pre-cat? anything else? or do I just have no chance at all?!

Push it..?

Seriously though that's the best you are going to get around town tbh, even if you bought a diesel it'll still be relatively crap on juice on town driving (My old A3 2.0Tdi 140) would do 35mpg at best round town..

Buy a VW Up, and put a GTi badge on the bootlid.  That wil get you a minimum 55 mpg.

I have a 2005 GTI manual, I used to average around 28 mpg but after a stage 1 remap by Revo and a pre cat removal, I know can easily get 33 to 34 mpg round the town. On longer runs I can get upwards of 45mpg when before it was around 38.

I would definately consider a remap if I were you. Obviously if you boot it all the tme your mpg will be a bit lower, but all round driving while still having a bit of fun, you''ll be pleased with your new mpg. Not only that but a big smile cos of the cars new alive feel.

well im looking at the same figures as you, im on stage 2, de-cat. ive been thinking for a while about getting terraclean. Ive just had a service and changed the oil i was using from 0w40 to 5w30 (not sure if that makes any difference) but i couldnt see a change in my MPG. problem with driving in sunderland tho is you can get pretty much anywhere in 10 mins! 

im going to give the guy a call tomorrow to book it in and will let you know if that makes any difference.

terraclean had recommended 2 garages to me, one an auto electrician and the other a window tinting place. on speaking to both of them i was asked if the GTI was a petrol. Clearly not filling me with confidence of even knowing where the fuel lines were i contacted terraclean who's UK boss replied to me giving me someone who is "technical" so thats who im calling tomorrow.

Hmmm interesting...so driven normally I could be getting a 5-6mpg gain which would almost get me to the 30mpg bench mark im aiming for...for some reason haha I would prefer 55 but thats never going to happen 

[trs888]

i drive normally most of the time, but cant get it to 30. i think its the location of the driving you do also, as i live up a hill, a long climb so MPG will be lower generally than someone who lives on a flatter area.

how many miles you get to a tank when the refuel light comes on? mine is around 275-290 even if the range says 315 miles after fill up!

[marcnazer]

Im not sure actually, I tend to just believe the range computer...next fill up I will be sure to reset the mileage and find out!

Pup the tyres up to full load level

[trs888]

I check mine every two weeks

Most 200bhp+ petrol motors are going to struggle to get 30 mpg+ around town tbf, unless they weigh 600kg. ;)

Is there any chance you could cycle for some of your town trips? Only way I can think of to reduce your petrol costs with the gti around own.

[jonnym]

At the moment I'm a averaging 40/41. That's including my final leg in traffic/town. If I go in for 9am, when I'm not shift working, I still get around 36 on the m25 car park!

im not complaining, i didnt buy the GTI with a misconception that it was economical. i absolutely love the car be it driving spiritedly or tootling round. its a great all round car too. i just want to keep it running in the best condition it can be in. Thats the primary reason for me to do the terraclean nearing 100,000 miles theres bound to be a fair amount of gunk thats built up. im looking forward to seeing the results!

If they use an induction cleaning tool then go ahead, but if they just use the red and black cans ,then avoid it, save your £100 as it will make little difference to your overall mpg.

It doesn't clean the part of the engine that is the part that can alter and improove your mpg.

I later proved that Terraclean did nothing to my intake valves when an injector was replaced and the inlet valves were still gummed up with carbon.
