sure this has been covered...but seeing as i am making an observation rather than asking a question, hopefully i wont get shouted at :scared:
since owning my 08 GTi for just 5 weeks, i have used V-Power on each fill up and standard Shell unleaded on only one. i have a spreadsheet for fuel...(yes, it is a bit nerdy but i am sure some of you guys do it too!)...and over a tank full i got 38mpg on 98RON and 36mpg on 95RON. the cost of a tank differs by £4 yet i probably will only get an extra 22 miles from the tank. on cost alone it might not seem worth it i suppose, but i feel "programmed" to use V-Power only.
-
I felt the same when I got my GTI, and for a good couple of years I used V-Power exclusively (believing it really made a difference), but recently I've abandoned it for the cheaper stuff.
-
its an age old debate 98 versus 95. i guess £4 per tank doesn't sound too much and 98 will be beneficial for preventing knock but in these financially difficult times, £4 is £4!
-
It's one whole pint!
I guess in reality the filler cap says 98 so there must be good reason to use it, I've just never truly appreciated the difference it makes.

never a truer word...
i dont think there is any additional benefit other than more protection against detonation...detergents etc are going to be the same. however, people report reduced power on 95...but that's hardly scientific unless on a rr.
-
i definitely felt a difference in torque when i used 99RON in my old 1.6. i know it's not scientific but once i went on a long hol and left the car with the folks and when i got back i thought something was wrong with my car - it took me a while to figure out that they would have put the regular stuff in while i was gone and that was the difference
i think the combo of slightly better fuel mileage and a supposed power advantage are enough to keep me buying the stuff. i only use Momentum 99 tho (Tesco)
-
The difference in power on my stage 1 is extremely noticeable between 95 and 98 ron. I always used 98ron but then over the course of the year I moved to 95 due to the cost. Six months later the car went kaput and was due to the fuel sensor going faulty. It was almost clogged.
I wont be touching 95ron again unless absoloutly necessary.
-
Although it may be £4 and you can't really notice a difference I'm sure inside the engine something is having to work harder to try and generate more spark/combustion, I'm sure our ECU magician dave a PD could explain in more detail if he sees this :popcornsoda:

I will ONLY use 99ron fuel and nothing else. What is the point in trying to save a few quid when it could cost you in the long run?
-
Surely it depends on what u want isn't it. Performance or fuel economy/cost. Rarely can u have both!
I choose performance so use V Power all the time, even if it's now costing me over £70 for a full tank! :fighting:
If mpg / cost is ur main concern then by all means use normal UL or get a hybrid/diesel!

Over a couple of years at £4 a tank that could easily outweigh the cost of fixing any problems that could happen. Doubt you will see any costly problems from the type if petrol used tbh in general, I bet more than half the Gti owners don't even look at the super stuff and there car will run fine.
-
I have only been putting momentum 99 in mine for a while now. Gotta love the clubcard points too. I can say i honestly noticed a real difference with 95ron fuel though.
-
V power gives you double points so you get £10 back easy on a gift voucher
-
Ok I just worked out that an extra 22 miles is a £3.69 saving.
So if it is £4 extra its actually only 0.31p more?
Thats at £1.40 for V-Power which is what I roughly pay.
If you pay more then the saving is more, as you have not put what you pay I can only go on what I pay.
Unless I worked it out wrong, 4.54 litres to the Gallon.
Anybody else want to do it, its all approximate.
22 miles over 38mpg equates to 58% so its fairly easy.
Its late/early so forgive me if I am wrong.
-
the important thing to remember is if your car has been maped, use the fuel it was maped with to avoide any timming isues , other wise you can use either 95 or the higher octane :smiley:
-
I find these arguments quite interesting as there are quite varied views from all members.
I dont think its fair to make a direct comparison in your spreadsheet between shell regular and V-power because as far as i know, V-power isnt just regular fuel with and 3-4 Ron on top which equates to extra miles per tank, you have to take into account of the detergents that are in V-power. If shell regular had these detergents as well, then yes, the spreadsheet comparison would be quite accurate.
I take a best of both worlds approach -i use 3 tank fulls of tesco momentum which is about £1.36 litre and 1 tank of v-power which is about £1.41 a litre.
This way, im exceeding the recommended minimum 98 Ron fuel as per instruction manual, saving a bit of money by using the momentum 99 Ron fuel but also benefiting from the detergents in V-power.
For members who use the 95 Ron stuff - There must be a reason why VW recommend 98 Ron fuel, they built the engines, have done all the years of R+D so must have a valid reason for recommending a minimum of 98 Ron fuel.
Im sure, the car will run with tyres at 25PSI, cheap oil that doesnt meet the required VW spec, cheap brake fluid that does meet VW spec, cheap non oem coolant or cheap gearbox oil but it wont be running at it's best. Most people wouldnt dream of skimping on stuff as mentioned above but will skimp on the fuel :stupid:
just my 2 pence

Very good points. :congrats: :congrats: :happy2:. Mine runs on V Power all the time. :happy2:

V - POWER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :laugh:

My Ed30 feels like i'm driving with the handbrake on slightly with the normal 95 stuff. I only used it a couple of times in the last two years out of necessity.
With 98 ron the car is much more responsive and reurns around 3-5 mpg more.
I've just had my quarterly V-Power statement and a £8.50 voucher off my next fill-up so if you can win on fuel spend, V-Power is a Winner!

i think V-power in the UK is actually 99 RON nowadays :happy2:

My Gti 2006 says 98ron.
I didnt realise till this thread lol. Ive been using sainsburys 97ron. Will be using 99ron v power once mapped mind as find VAG cars seem to run better on v power over momentum. Was other way round on my old RS. Weird.
When the kids were not at school i was seeing 40mpg to n from work. I dont even hit a motorway either. Get about 32-35 now because of traffic.

More importantly, how on earth do you get 38mpg ?
I struggle to get 30 on Tesco99 and I'd be down around 28 on normal 95
-
I find in my stage 1 Octavia VRS mkII that it runs better on momentum. I tried V power but it felt flat whereas with momentum it has more mid range grunt.
-
Lucky people having the choice over here in ROI its 95 or run out :sad1:

it's a shame as people over here have the choice and still use 95 Ron... :sad1:

I always use Vpower and my mpg is horrendous :mad:
Although I thunk the car performs better on Vpower and pulls more urgently
-
I run my Pirelli stage 2 on V-Power or Tesco99, it is a little sweeter and crisper on V-Power but pulls hard on both. I would not run 95 for risk of knock and the map retarding the ignition timing which would mean rubbish performance and mpg until the map adjusts back.
How do people get 38 !!! I average 27.0mpg and that is a fair amount of motorway journeys. On a 120 mile motorway trip I will only see 29-30 at best. I have tested my mpg and it is virtually spot on checking via a full tank between refuelling, are some meter out ?
-
I try and run Vpower 99 or momentum 99, if that's not near where I am then the next best thing is super unleaded 97 which BP, Esseo, sainsbury's, etc sell. Only if I'm desperate I go on 95.
Mainly use Shell and Tesco for the discount schemes, just got £5.50 off at shell and now I'm a v power member and have the magazine.
I normally get between 300 and 350 a tank.. I've got near 400miles before but went through loads of average speed cameras and stayed at 60mph in between but normally get bored and fuel economy goes out the window.

i guess i have a light foot...dont constantly boot it...mainly use the power for overtakes. sure i could get more if i tried :ashamed:
Filler cap on mine says 95 is grand.
mine too says 95 is a minimum but 98 is recommended...suggests that there is nothing wrong with putting 95 in or that the car will have an early death if 95 is used.

i too checked my spreadsheet calculations against the on board dash mpg and they were the same...spooky. i get 38 regularly...thought that would be the norm for normal motoring...and that's without having cruise! a light foot, no need for harsh acceleration, keep constant speeds. lmy daily journey consists of a major A road that is clogged with lorries and is hell...so usually i sit at 50 - 55 mph for approx 23 miles before a little town work. on the way home its 28 miles of B road where i can pretty much stretch its legs, but normally sit at around 60 officer!
at the end of the day, i am sure i will continue to put V-Power in...but i certainly wouldn't use supermarket fuels...but that's maybe a different thread!! :evilgrin:
-
With judicious use of the right foot and cruise control, I've managed 40mpg on a journey which I'd normally expect 32mpg.
The car is designed to run on both 98 and 95 RON - it makes the necessary adjustments but remember the quoted power (200/230 bhp) is based on using 98+RON.
Have personally found V-power to provide more "oomph" where as Tesco Momentum provided better mpg.

Optimal tyre pressure, no aircon, windows wound up, no junk in the boot? :signLOL:
-
I think the original posters mpg might be out a bit. I wouldn't get 38mpg out of my STD gti dsg even if I drafted a lorry down the motorway at 50mph
-
A higher octane fuel does not contain any more energy or power than a low octane fuel but it is more 'knock resistant' so will allow the ECU to advance the ignition timing more than on a low octane fuel.
As a general rule, the more advanced the spark timing, the more complete the combustion is. A combustion that is cleaner and more complete is more powerfull so its also more efficient.

The ED30/Pirelli engines are a little worse on MPG compared to a regular GTI (based on the offical figures), then you have added stage 2 mods, which can't really make it better?
Anyway, I'm another person which can average 38mpg (commuting trips with 25% motorway). My tips would be:
Go easy on the throttle
Look ahead
Tyre pressures 2.4BAR or a little more
Regular spark plug changes
-

I agree with the above, i used to have 32 psi all round but recently went to have 4 wheel alignment done and the technician said i should have 36 PSI. so now with 36 PSI in, the handling feels better and mpg has improved.
worth a go?

-
I run at the standard pressure of 2.6 bar which works out as 36-37psi.
-
I think these greedy oil companys have been VERY clever in how they have marketed these "premium" fuels.
I use regular UL purely for the cost.
-
Use V power and join the V power club then you get cash discounts. I use this and Tesco 99 Ron.
-
I used to get 38mpg on ED30 stage 2+ but, no idea why, ever since I fitted a Twintake I can get no better than 30mpg.
Anybody else experienced this?
-

Yes, if you drive to the moon and back as your daily commute.

Alan - I do approx 8k miles pa and have just received a £8.50 voucher for the last 3 months so I think you're 'slightly' exaggerating :P
-

I find the same but I also find my car totally poops itself if I don't put v power in, think it ran for 5.5 years purely on v power so when I was skint and had to put the 95 ron in it had a total hissy fit and starting blowing that horrible gritty smoke out the back! Also car feels really sluggish on the 95 ron so I try to avoid it as much as possible.
I usually get about 350 miles to the tank and mpg of 31.8 on motorway journeys, I have had as low as 9mpg on a quick blast from my house to shops though :ashamed: usually get about 24-26 running about town. I have never seen my car get over 33mpg but I don't drive very economically....
-
Hi i have a round trip of 34 miles to work and regularly see 38 mpg,although the roads are very quiet at 03.45 and i am very rearly out of 6th gear.i have stage 1 with millteck tbe,but when friday arrives(pay day lol) i have seen single figures lol. my wife constantly tells me i dont deserve to own a gti driving it like miss daisy. anyway V POWER all the way has run on this for the last year religously with no probs at all.
-
Regularly see 38mpg now but in city traffic its in th mid to low twenties. A steady drive without harsh braking or acceleration is the key to good mpg.
I have seen very little difference in mpg from using 95 vs 99 but there is a noticable difference in performace, particularly the top end of the rev range.
Running on 95 will do absolutely no harm whatsoever to anyones engine. Think of all the A3 / A4 2.0TFSI's out there - not exactly owned by enthusiasts who give a stuff about detergents and such snakeoil. They seem to manage just fine. Maybe won't make the factory quoted power output but thats about it. Loads of countries / places in Europe where its difficult if not impossible to get better than 95 RON. Again the roadsides are not littered with broken TFSI's ...

here's how i did it...brim to brim...zero'd trip...351 miles travelled, 41.53 litres added (9.13 gallons) = 38.46mpg (98RON). happy to be corrected. second tankful, 38.31(98RON), 3rd 36.38 (95Ron). :grin:

You only managed to get 41 litres in? The tank holds 55 litres so it was no where near empty. I have a habit of driving round with the petrol light on so regularly fill it up and manage to get 50+ litres in. This is probably why your mpg figures are high.
I used to use an app on my iPhone that worked out the mpg but haven't filled it in for a while. I can get high mpg on single motorway journeys if I'm using cruise control, but over a whole tank it's probably high 20's/low 30's. A lot of my journeys are around town
-

Whether you fill an empty tank or a half-empty tank is immaterial. Fill the tank until the nozzle clicks shut, zero the counter, drive, refill until nozzle clicks shut. You now have a distance (from the counter) and quantity (from the amount of fuel entered). It doesn't matter whether you drove until the tank was half-empty or completely empty, it can be calculated each way.
I've achieved 40mpg by sticking at 60mph (via cruise control) on a 250 mile run.

Couldn't agree more, my commute to work is 80% DC and Motorway 58 miles in total. Very close to 40mpg this week, driving at the speed limit using 95 unleaded.
My old S3 1.8T would do around 34mpg with the same driving style.

Yeah true, my bad. I'll put it down to a long day and being tired so not thinking!

Exactly, it doesnt matter at what point you fill it up...drive till your on fumes or drive 100 miles...so long as you fill until the nozzle clicks off and calculate from there. Thanks for backing me up there Stealth :happy2:...thought i was going mad as that's the technique i have used for years.

ROFL. They've used the same technique on TG once.
