I had a 5p off per litre from tesco a few weeks ago so decided to try their 99 fuel.
About halfway through the tank I Noticed a massive improvement in the way the car pulls and also managed to get 350 miles to a tank compared to the usual 300.
I filled up with v power as usual this week and this weekend the car just doesn't feel the same also at 250 miles and will need to fill up soon
Have scanned my car for fault codes but there isnt any
Can 1 Ron really make this much difference? or am I paying v power prices for normall unleaded at shell?
I will be filling up with tescos finest again this week to see if it is the fuel
On another note I have noticed that at shell unleaded has dropped by 5p per litre here in the last week but v power is only down by 1p
-
no idea, I think i'll have to try some tesco 99, my car is only been running on V power so it would be good to see if I notice anything
-
V-power and Tesco are both 99RON :happy2:
-
V-power and Tesco are both 99RON :happy2:
Probably the old optimax I was thinking of
They dont seem to put the Ron rating on the pumps anymore
Maby it's the quality of the additives but you would think the most expensive fuel at the pumps would be the best
-
They are both 99RON now (unless abroad and vpower is 102RON iirc)
I use both and tbh I can't tell any difference, but then my car is standard. I used to put V-power in religiously but as I either have to pay a toll there and back to the nearest station or a 35mile round trip I now use Momentum as its on the way to work and was 135.9 this week, cheaper than vpower. But if I'm away somewhere if shell is nearer than a tesco then I'll use it
-
After using Tesco 99 for months I have now swapped over to V Power. I have noticed a slight increase in mpg over the tesco fuel.
I have a standard '05 gti. My run to work is 10 miles and would get 34 or 35 mpg with tesco 99 and now I am easily getting 37, sometimes 38.
I think the car feels a tad quicker too.
I always have heard that supermarket fuel is of a lower quality than that of the branded companies like shell or bp. I was told that when the big tanker ships are quality checked, if the fuel isnt quite right, like the s.g., it is sold at a lower price to the likes of the supermarkets. The fuel is still good, but of a lesser quality. Whether this is entirely true I' not sure.
-
Vpower Racing in europe was 100 when I moved back to England in December
BP ultimate in Germany (Aral forecourts) is 102
I miss it.
Oh it cost me 90cents a litre too, Send me back!!!
-
I've always found v-power gave the car more oomph but Tesco 99 gave me better mpg.
-
Maby it's just a bad batch of v power
I had a faulty DV up untill last weekend when I had 3/4 tank of tesco99 and noticed an improvement But initially put it down to the DV, But this weekend with under quarter a tank of v power it just doesn't feel the same.
Think I'll do my next 2 tanks with tesco again and the 2 after that with v power to get a proper comparison
It's a bit out of my way to get the tesco fuel as shell is just round the corner from work but another shell 2 miles from that one is slightly cheaper but Due to the traffic not worth going to
-
I've always found v-power gave the car more oomph but Tesco 99 gave me better mpg.
Exactly this , for my car too.
-
i used to think that V-Power gave me better mpg but considering i use them interchangably and it would take 2-3 tanks for the car to adjust i don't think there's anything in it really
there's a Tesco petrol station (2 actually) on the way to work, with the cheapest petrol i've seen in months. if i need V-Power there's one on the way to my gym, so i still use them basically interchangably.
-
Had my ED30 since October and it gets 1 tank of V Power to about 2 or 3 Tanks of Momentum 99 and can honestly say there is no noticeable difference between them, only diff you notice is in your wallett, especially if you have a 5p litre voucher for 99 (In which case its about £3 a tank full difference :happy2:) :driver:

Ive also found that. V-Power vs Tesco 99... no difference to me.
-
I find tesco 99 to be better. always find i get terrible mpg on v-power and the car just doesn't seem to run the same.
plus v-power tends to be 5-8p more expensive than tesco 99.

I've never used Tesco 99, just exclusively V-Power. The Shell stations are easier to find on my journies. Good to know that there isn't that much difference.
-
I only ever use Tesco fuel in both the vRS and Golf and find them absolutely fine, I would be interested in doing a few runs on V Power to see if there is any difference. :popcornsoda:
-
I've been using v power for the last 3 tanks then filled up with momentum. Not really noticing much difference in performance but I'm getting about 1-2 mpg more (at least) for my usual commute to work.
-
I use Murco 95, is that any good? :popcornsoda:
-
My GTI thrives on Tesco momentum :happy2: when run on 95 in the past, I've felt a horrible flat spot between 5.5 and 6k revs :scared:
-
my vote also goes for Tesco. when i was running my evo 8 (400hp) as a daily i had all sorts of issues for a while which after about 500 quid turned out to be fuel related - after many frequent tank dips/tests after fill ups at both shell and tesco, it turned out v-power wasnt quite what it said it was.......(car was pretty borderline mapped to eek power) thereafter i stuck with tesco 99, no problem whatsoever...
at the end of the day i guess engines /maps could act differently in answer to fuels?, since its all the same stuff initially until they add all the proprietry additives, especially in the higher octane options at the pump
-

............it's fine along with Morrisons & Asda own 95. :laugh:

.........i just filled up with some of that right now... oh, thats Merlot...... :confused:.... :drinking:

Vpower Racing 100 octane for the last 5 years or Bp 102. Now I'm back in England momentum or Vpower whichever is most convenient.

Wasn't one of out tuners doing a test of the fuels on an ed35 for tv a few weeks back?
Were any results allowed to be published yet?

Rtech nick but didnt include momentum, hes going to do his own b2b dyno testing again including momentum :happy2:

TBH i absolutly hate Tesco momnentum ! Dont get me wrong in the gti and edition 30 the car run fine on the stuff both performance tuned and standard ! But when in the M3 and RS the both cars hate the stuff the cars feel lumpy and the zorst pinks like fook ! The make up of the fuel must not be right for these cars, like i said though i never noticed this on the gti though, switching to v power though the cars feel and drive perfect even on standard esso 95 ron this never happend !
I will say though i used to put it in golf instead of v power but both the m3 and rs have only had it in once or twice and it made for a noticably bad drive, i dont even use it if i have the voucher anymore its v power or standard premium for me !
It does make a differance to performance though and a lot better for your engine especially on the TFSI cars
-
Revo Kev told me to stick with V-power when possible stage4 wont like the tesco99. Had no choice one day and went with bp ultimate which resulted in a flat spot (i think). Havnt been back to V-power yet to test as car is away getting painted. Cheers, Stevie.
-
i use v-power most of the time but tescos 99 near the end of the month when im skint ( tesco pay at pump lets you fill up a full tank even if you only have a few quid in the account :grin:)
went for a country lane run on sunday and found myself 60miles from home with the fuel light flashing, only station i could find had 95ron, stuck some in and set my car to 95ron map and i was shocked, car felt flat, boost felt lacking and overall no were near the power it makes on 99 :driver:
-
.
Apparently, if tuned for V-Power/99 and you have to fill with 95 RON, it will take a good half tankful or so before you will feel the inferior results.

i found it was a instant drop, maybe had more to do with me dropping to apr 95ron map, with such a diffrence i cant wait to go from 99--->104 ron :jumpmove:
-
^^^^
Yep, gotta be due to dropping to the appropriate map - Your experience actually proves the difference!

Not exactly. If, due to the fuel, it can't run such high timing, boost, etc it will correct instantly rather than give pinking or knock or leave the engine running at dangerous levels.
That's what these engines do.
-
Im thinking it is a problem with the shell station that I use near work it's more expensive than another shell just over a mile away but I normally just use it because it is handy.
I filled up at the other shell and the car feels the same as It did with the tesco fuel!
I won't be using the shell station near work anymore unless I really have to

Which shell is that mate?

The one at the airport

The one at the airport
I tend to use the one in Bucksburn as its en route to town - no issues there but I do think my car is running better and more economically using the Tesco. Do have to go to Westhill though as the Inverurie Tesco doesn't do momentum.

It's the one in bucksburn that I'm using now, I would use tesco but only really go near them when I go into town.
The Inverurie tesco is annoying as they have signs up for momentum but none at the pumps, would be very handy if they did!
The shell just outside Alford has v power

Instead of having a shell shop they have a budgens or spar or sell things you wouldn't have in a normal shell garage

Yeah, found that out about Inverurie when I pulled in because they had the signs up - parked next to a pump and it was just 2 pumps of bog standard unleaded! :fighting:

Hedge am I right in thinking that although my car is mapped to 99RON (R-Tech custom Stg1) it will still run safely on 95 or 97 RON if that's all that's available (or I fill up on 95 by mistake)? I understand the OEM map is set to 95RON (in the uk) so anything stronger is a bonus. . . :chicken:
-
OEM map is for 98 or higher as per your filler cap. :wink:
Perhaps you should ask Nick what his map would do. My guess is it will run but not optimally.
I'm not sure what the reduced octane will affect timing or boost wise but there will be some changes.
-
I always run my stage 2 scirocco on tesco 99 it seems to run better on that than anything else!
-
Also with Tesco99 you get tesco points and vouchers which means free fuel, shell dont seem to issue vouchers as often regadless of how much i use.
-
I have run every car I have owned with a turbo on Tesco 99 including my 09 GTR and my scooby track car and I am sure I can feel the difference. It also seems to give a few more mpg the Shell but from what I understand the only real differences are that the Shell fuel has more additives in it than the Tescos.
-
.
It seems to me that anyone running a GTI or performance car on the road is best off running it on either Tesco 99 or V-Power but should avoid using any other fuel.

My regime is 1 Tank of V-Power (purely for the additives) to 3 Tanks of Momentum 99, that pretty much covers me for 3 months anyway :signLOL:

My filler cap says 95RON - although Im not opening that can of worms :grin:
As standard it felt very flat on 95RON so I avoid it like the plaque now it's mapped.

I use Tesco 99 all the time , but with a good measure of Redex in every tank :happy2:

Which I interpret as meaning that you are advised to run on a minimum of 98 RON but may run on 95 if you can't obtain it. All as advised in the GTI Handbook - RTFM!! It says that if you are obliged to run on 95 "in emergency" you should "drive at medium engine speeds and avoid high engine loading". Hence why reputable tuners insist you use at least V-Power or Tesco 99.

So in the above picture (Ta Robin) it says 98RON / 95ROZ not 98 or 95 RON. :smiley:

....I never noticed the ROZ but what's the difference between RON and ROZ? - I can't find anything via Google.
-
I could only find ROZ – Research-Oktanzahl - German for Research Octane Number. :wink:
-

....So I'm inclined to think that RON and ROZ ratings are the same and that my fuel flap label is merely stating that the car can use either 98 (in 2005) or 95, and that more advice is written in the Handbook.
Long story short = Use 98 (minimum) whenever possible and only use 95 in emergency and granny drive accordingly.
This of course is advised and written by VW for their standard OEM cars, not ones remapped by mad Englishmen.
-
I would agree with that Robin. :happy2:
-
my cars filler cap also states 95 ron. Could it be the later cars that the filler cap states 95 ron (BWA engines)? Just a thought
-
My Ed30 states 98 RON and only gets 99 ron :happy2:
-
Mines the same as robins and apart from the first couple of tanks since owning the car it has only run momentum or v power and premium unleaded in emergencies (usually 97RON from esso etc)

Mine is the same as Graeme's cap - also an 07 build.
Darn early GTIs with their blue glass, no aerial and a better fuel recommendation :P
Anyways, regardless of what the cap says, just stick some decent fuel in and we'll all get along just fine :happy2:

my 05 reg GTi was 98 on the lid, and my later 07 std GTi was 95.. Might be due to engine code type..

the mk6 GTI says 95RON. mentions nothing of 97/98/99 etc.
i always use VPower or tesco 99. only time its had anything less was when i picked the car up new with 1/8 of a tank!

^^^^
Judging purely from the filler cap labels it's sounding as if VW have revised the engine to better accommodate 95 RON in later Golfs.
Those with 95 RON labels: What does your GTI Handbook say?

Nothing much really. Says you can use petrol of a higher RON number than is recommended but it makes no improvement on fuel consumption or engine power.
Also encourages the use of fuel containing additives to stop corrosion, keep fuel lines clean etc.

....That's taking a directly opposite stance about RON to earlier cars like mine. Perhaps VW thought that people were too thick to understand the label and think that sales would be effected when they saw 98 RON on the label and thought the car would be more expensive to run.
It surely can't be a generic petrol Golf label because it includes tyre inflation info and surely that's different on the GTI?
Anyway, either V-Power or Tesco 99 is the way to make progress.

I'm sure I read somewhere that they released the tsi engined gti for use with 95 Ron.
In Norway you get 2 kinds of v power from shell 95 and 98 Ron would that sticker be for the Scandinavian market?
