Title: 41mpg!!!!
Post by: Deako on July 16, 2009, 03:11:07 pm
Took the GTI on a 40 mile round trip to one of our Remarketing sites today to discover why the comms room was losing power when the generator kicks in, and upon arrival had gotten 39.2mpg average for the journey. Same roads on the way back, and when i got here the average had topped out at 41.2mpg.

OMG. Im pretty astounded by that to be honest. If i cruised in a relaxed manner in our old Ibiza 1.4 16v Sport i could only just get 43-44mpg.

Admittedly i didnt use the loud pedal that much. So most the time the car was off boost (50mph road works on M6 too), but that is very good even for a 2.0 engine.

Has anyone else managed to nurse a GTI above 40mpg? Or is the temptation to plant the right foot too much?

Just filled mine up and just before I did it said  154miles on the trip from the last refill and 45 miles left in fuel. Once I topped up to the brim it said 190 miles on the range :surprised:

Must have been having fun! :evilgrin:

On a 55 litre tank (12.1gallon) that works out at..................

15.7mpg :scared: :scared: :driver: :rolleye:

Sorry for the threadjack Deako. :ashamed:

The most I've ever eaked out from a tank is an average of around 38mpg when I was on the APR stage 1 map.

The most I get from the Stage 2+ REVO is around 32mpg.

There we are, back on topic :happy2:

LOL. No worries guys. Its still fairly on topic!  :signLOL:

I managed 45mpg out of a Mk2 Golf running an ABF 2.0 16v. It was a peach too, running really nice power.

Ive had nearly 600 miles out of 2 full tanks. With mostly short journeys, so im not having enough fun in the car compared to a few of you.  :grin:

Managed to get 42ish  on a LONG stretch of road where 50mph was the order of the day.

Wasn't as boring as it sounds it would be either.

In my experience its a very jekyl and hyde engine, very frugal when cruising but equally thirsty when you press go.  On balance its pretty good for what it is and I'm glad I've got the flexibility to go either way.

Ill have to host some. Converted it to a VR6 in the end, took me 3 weeks using my mates garage/ramps and tools. Errm, it didnt get 45mpg afterwards.  :signLOL:

Ive had 15x Mk2 Golfs though. Most modified with engine conversions in one way or another.

I can regularly get 40-41mpg if I want - on my way to work and back.
22 mile run, on a mix of M11/A406/A13

I always fill up my tank when it gets to the last quarter mark, and get around 320-330 miles to that point - with the computer still showing another 80-100 miles to go.
On a longer run, I reckon I could get 420-450 miles to a tank if I wanted.

In fact Im driving around 300 miles up North on Tuesday, then back later in the week. Wont be putting my foot down since I will have the wife and kids with me. Will see what I get and report back  :wink:

I've got no chance of any of these figures...even if my car went back to stock.

Sheffield is basically built on seven steep hills and it completely buggers up the fuel economy :sad:

My morning commute would regularly return 37 - 39mpg.

I often go up to the midlands to visit the 'rents. Almost always, I'll average 26mpg. Even if I try and restrict my heavy right foot, I barely get anything above 30mpg.

However, I once got around 42mpg (over a 150 mile journey) by using the cruise control. Even then, I reckon I could have got more if I didn't blip the throttle every now and then.

32mpg on my regular commute.
the speed is the key above 60mph the economy drops like a stone on the GTI

Post by: big al on July 16, 2009, 07:50:56 pm
In my MK3 16V the best I ever got was 42.8 MPG, the worst was 7, Although this was a much lighter car, still not bad for something 13 years old.
My MK5 gets about 31, managed 39 recently.

Does Cruise Control really make that much of a difference?!
Thinking of having it fit...

Yeah but I was doing 60mph. If you can keep the car at sixty without too much throttle adjustment, you're going to get high mpg. If, on the other hand, like me, you can't keep off the throttle, then you're gonna get low mpg. When I'm using cruise control, both feet are on the foot rests on either side of the pedals, so no temptation to floor it.

Speaking to another owner, there was a dealer up North somewhere that ordered 8 in Llahsa for a promotion, all 3 doors.

Back on the mpg issue....

I have just returned from a dirty weekend in York, then a few days in Newcastle followed by a few more in Falkirk then back home to Peterhead, North of Aberdeen.

Took it steady, pretty much adhering to speed limits all the way.

My average mpg over 990 miles of driving......38.5mpg. Pretty good for a 200bhp petrol car!

I had the odd moments when I had to stop a focus ST driver from thinking he was in a Ferrari, but generally just as I said, not driving like a granny, but adhering to the limits...most of the time.

OOO also, gotta say, after 990miles in 6 days, both the wife and I thought this car was the most comfortable we have owned. Especially good after 2 nights in the worlds most uncomfortable bed in the Ramada in York!!!

I hope you had a really nice time Andy, but unless a lot of it was very twisty, almost 1000 miles adhering to the UK's wonderful speed limits sounds like purgatory to me.  Even a metronomic 70 on a motorway could hardly be described as adrenaline pumping.  :indifferent:

Mate, had a nice bit of fun on the roads north of the M8 around Stirling - never got sideways or crossed my arms Im afraid.

Only thing I can say in defence was that this was meant to be a relaxing week away from the kids - its really amazing how calm you can arrive at your destination when you have driven in a law abiding manner! Certainly surprised me!

On a seperate point, I can confirm my car will it 140mph and feels rock solid at that speed - unfortunately, the PRIVATE test track I was on ran out of road to go any faster  :ashamed:

I normally know I've done well if I manage 370 miles to a tank in the ED30.

Short journeys to work everyday doesnt help things.

I expect this to get better after I rack the miles up. She's only done 20k at the mo.

The third day I had my GTi, I travelled from Northants down to Portsmouth + return.
I sat between 70-80 on the Mways and gained a solid 39.8MPG round trip, with some needless flooring considering I'd had the car a matter of hours.

They're well capable of a reasonable return if the Turbo's not called into action unnecessarily.

Are these readings entirely accurate because the speedo is about 10% out according to your satnav... the reason this being is... the law allows u to be 10% under but not 1% over... :stupid:

Absolutely, for a true representation you really need to work it out based on filling the tank and actually working out how much fuel you have used over a certain distance.

depending on the year of manufacture some are closer than others to 'true' mph.
Some are proposed to be almost spot on which can be 'tricky' if you assumed it was 10% lower (like almost every other can on the road)
(assuming your sat nav is accurate too)

According to my TomTom I am about 5-7mph out.

Anyways, drove up to Middlesborough on Tues (still there!) with a fully loaded car - both boot full, and car full with passengers.

About 240 miles. All motorway. Only manages about 33.5mpg - which is less then the 38-40mpg I normally get on my 20mile work run!! Im putting it down to the fact I had a fully loaded car, and *may* have have been running along at 3 digits at places.....lol

Its more of a percentage rather than a constant amount of MPH that you would be out. For instance on our recent trip to the ring at high speeds on the German autobahn's the clock was around 20-25mph out!  :happy2:
