Guys,
The fuel octane debate has raged and raged and raged...
I'm not interested arguing over RON values, Tesco's 5% biofuel content or whatever, simply what do you feel makes your GTi run better... Shell V-Power, or Tesco juice?
For the sake of 1-2p a litre, I'll fill the lady up on whatever is generally accepted as better! :laugh:
-
I use Tesco 99 over shell, main reasons being my local fuelstop is tesco, i get my clubcard points, but comparing the 2, i get identical performance, mpg when ive used both types of fuel when ive been nearer a shell stop.
My nearest shell garages have had credit card fraud on a number of occasions, and i try and refuse to go there using my debit card.
I dont trust them with my card.Im not mentioning Nationality.
Sorry, thats just my experiance.

Had to fill up with BP :sick: the other week as the local Shell is having new pumps fitted.
The nearest Tesco fuel is 17 miles away :sick:
For me - Shell first, then Tesco, then BP Ultimate as an emergency. :smiley:

Thanks Phil, Hurdy.
I've got a huuuuuuuge Tesco about a mile away, but for some inexplicable reason it doesn't have a fuel forecourt. :undecided:
I use Tesco 99 (mainly for the points), but I was interested in you guys' experiences. Might give the Shell a few tanks.
-
Which I had a choice!!!!!
No shell or tesco 99 ron pumps within 15-20 miles of my house and the car is rarely used outside this zone. 80% of stations around here are texaco so this is mainly what I use.. only 97 ron though :angry:

I chop and change between the two and don't notice any difference.

Nice one :laugh:

when i had my mk 1 octavia vrs it was a different cat ran on v power so i ve used ever since :smiley:

....
My late Godfather was very senior in the Shell organisation in The Mediterranean and I feel an inclination to honour his memory and all his support, so I wouldn't consider using anything else as long as it suits my car, which V-Power does.

I think I have to say the same .... generally .... though every now and then I feel the car is livelier - and on each of those occasions I have had Tesco 99 in the tank !
-
Complete opposite to SO8 - I feel the car is 'livelier' after filling with shell V-power. I only feel it on that first journey out of the station. Otherwise, I've chopped and changed between the two. When I lived down south, I'd fill up with Tesco's 99-RON stuff. I could then make a 200-mile journey up north, fill up with V-power and head back down.
Honestly feel V-power has a slight edge over Tescos but it's very slight and short-lived.
-
Theoretically there shouldn't be much between the performance you get from Tesco 99 or Shell V-Power as both have the same RON rating. The difference will come over a longer period of time. Running on Shell V-Power - The reports I've heard are that the RON rating is much more stable and that the fuel has more additives in it to keep the engine healthier. Tesco runs a larger element of bio-fuel in it's make-up and so could be an issue for the FSI engines over the longer term in terms of keeping the engine clean and longer term maintenance of the power outputs due to build up of deposits. :smiley:
-
I travel out of my way to use Tesco's 99 and quite often they have none left.So go back along the route to the Shell station I passed for V power.
Slightly off subject....
Very Cherry... Your in Penzance... Where do you go.The Tesco there is,nt 99 and all the other garages are local stuff.AFAIK the nearest good stuff is back way out on the A30,(Shell).Just wondering if you know somewhere nearer.I fill up on the way in but always run out and end up using the bollox.

use to always use either tesco99 or vpower99 and as others if an a emergency then BP 97.
now only vpower - revo advised when I changed map to them to only use vpower if you are running a high timing setting.
they say vpower is more consistant, where as tesco super varies quite alot from pump to pump.
doubt it makes much difference though if you are stock or have a generic remap

Interesting...
Think I'm going to run the old girl on V-Power for a month and see if there is a discernable difference. :laugh:

Huh, please explain! :huh:

You got that the wrong way round. It is the Tesco 99 which has been repeatedly proven to be more stable. Thorney Motorsports have systematically proven this, as have Revo. V-Power is much less stable than Tesco 99 - the only time it is on a par with Tesco is when it gets delivered by the bulk tanker.

That is wrong too. By law, ALL UK and EU unleadeds, weather poverty spec 95 RON or BPs 102 Ultimate - all have to have 5% bio fuels. But being as GreenErgy, who make the Tesco 99 brew have been using bio fuel base-stocks for years - they have far more 'bio ethanol' experience than the traditional 'crude oil' based oil companies. And Tesco 99 uses an advanced additives package, which is on par with any other UK fuel, super unleaded or otherwise.

Nope - you are miss-quoting Revo! Revo state that Tesco 99 is more stable than V-Power! Just ask Kev or Carl.
-
Having tried both, I think the Tesco 99 is slightly superior. As I have a Tesco quite near to me (and no Shell station) I always go there and get the clubby points too!
If I am going on a long journey I look for Tesco PFS's along the route. In fact, if you go to the Tesco storefinder website you can download the locations to your Garmin/Tom Tom. Sad isn't it.

Nope. I've got Shell stations on my TomTom. Have to figure out how to stick them on the RNS though.

V-power has more additives in than Tesco to help keep the deposits off the valves etc.....or at least that is what they purport! :smiley:
I thought that V-Power was the more stable of the two?!?
Are you telling me Tesco 99 doesn't have more bio-fuel in it's make up?

Then Shell are feeding you mushrooms - Tesco 99 has an highly advanced additives package, easily equal to what the 'major' oil companies claim. What's more, log onto www.GreenErgy.co.uk, click on the contact us button, ask them what additives they use, and they will e-mail you back with their full additives package. Shell, BP, and the others certainly don't do this - they are more than happy to spout about what they claim, yet completely fail to back up their 'claims'! :rolleyes:
Seriously, Tesco 99 is categorically the best 'pump fuel' available in the UK. OK, there is the BP Ultimate 102, and when it is fresh, it is superb. But at just 10 stations around the country, it is hardly gonna be 'local', and it suffers from horrendous degredation - for £2.50 per litre!!! :shocked: :rolleyes:
I thought that V-Power was the more stable of the two?!?
Nope, other way round. Ask Revo, and ask Thorney.
Are you telling me Tesco 99 doesn't have more bio-fuel in it's make up?
Tesco 99 has EXACTLY the same bio fuel content as V-Power, as well as every other 'petroleum-based' unleaded. But GreenErgy supplied Tesco fuels had been using bio-fuels for many years before the likes of Shell added them, and so have a massive 'head start. And don't forget, GreenErgy are the UKs third largest petrol retailer - so they ain't no 'cottage industry' oil company!
HTH

I dont shop at Tesco as I hate their business tactics and their stores are really bland, prices are not that good and they are generally really dull.

And you really think that the 'business ethics' of Shell or whoever else are any better? :rolleyes:
As far as I'm concerned, I couldn't give two figs on their 'ethics'. The simple FACTs are that two completely different companies have PROVEN that Tesco 99 is the best fuel on the UK forcourts - better than V-Power, better than BP Ultimate. And it is soley that which helps me decide what fuel to use. An the last time I checked, I didn't think that unleaded petrol could be made in some Chinese child sweat-shop - unlike Tescos, or even M&S t-shirts . . . :smug:

Erm, GreenErgy were using bio-fuels for a good five to six years before Shell - so in the corporate/commercial world - that IS a massive head start. :smug:
And I neither work for, nor have shares in either Tesco or GreenErgy. I am just happy to recommend a good product. :rolleyes:

In what way has Tesco 99 been "proven" to be better?

Use the search function old chap! And use some keywords like Thorney Motorsport, fuel tests, etc. You will then soon realise that we arn't just talking tosh!

I use mainly Tesco 99 and occasionally V-Power.
My old ED 30 used to run great on Tesco 99, even the exhaust note seemed to sound that little bit "raspier". It does take a while for the ECU to adapt to the different fuel though, and I thinks it's best to fill up at least a few times with the same petrol before making a judgement.
Another tip I read is to fill up when it's cold, apparently the petrol is more dense when cold, so you get more in your litre ?
The Thorney Motorsport Fuel Test summary was :-
QUOTE :
In simple terms, Shells V Power is near identical to the Optimax product that it replaced, in power and ‘feel’ terms it continued to out perform all 95 octane fuels and we’d still recommend owners of all performance cars use the highest quality fuel they can find. However the performance offered by the fuel was sometimes inconsistent.
The Tesco 99 fuel again outperformed V Power in all the tests but the differences between the two fuels were marginal and we doubt most people would tell the difference in their cars on a day to day basis. However the Tesco fuel was the most consistent. ...
........Bottom line? Use the Tesco 99 fuel where you can find it, it offers the best, most consistent performance of the fuels available and it’s cheaper than V Power. If you can’t find a Tescos that sells it then go for Shell’s V Power. :
-
Yes it's best to fill up at night or in the morning as the petrol will be colder and denser. Jeremy Clarkson mentioned this once.

Im going to experiment with some V-power for a few tanks. Just had some data logging done since my remap, and it shows that the engine ignition timing gets very erratic on the odd occasion, sometimes back to -6 degrees, which is getting close to detonation territory :lipsrsealed:.
Whereas another Ed30, same map as me, dsg, has stable ignition timing on his logs but he uses V-power as gospel.
Ive been advised to try it to see if the car runs better on a different fuel with this identical map.
Perhaps it maybe worth considering running V-power when at a Tuned State rather then standard form.
I will update once i have run a few tanks. :smiley:
