    I use tesco almost exclusively, and its perfectly fine.

    I'm there anyway doing the shopping, whereas i'd have to drive to Shell and its in the completely opposite direction AND more expensive.

    Tesco also do 5p off vouchers pretty regularly, so it works out the same price as standard juice.

    Good news,
    Now all i need to do is convince the other half we need to spend £50 three times in short space of time for the 5p off vouchers !

    sometimes, like the other week, they have signs by products in the shop saying 'buy 3 tropicana 1.5l bottles of juice and get 5p off per litre of petrol'

    it changes weekly. its been juice and lynx body spray that i can remember

    I use this when I'm not by a shell garage, which is most the time, it's still 99 octane which is what vpower is

    I agree with all you guys, when I used to run forumula fords where every last hp is critical we did dyno tests with every higher octance fuel availible (from the pump) and tesco 99 came out on top, ran it ever since.

    No issues here, but then if you can run a diesel on used chip fat I don't suppose running different types of S/UL fuels should be too bad.

    I've always wondered whether Tesco fuel would put any extra strain on rubber seals (degradation) with its magic mix, but no evidence of this so pure speculation.

    Was strangely enough talking to an old boy yesterday about this... he had a wierd theory ( that would be almost impossible to prove...
    )
    V power is the best out of pump fuel, Its made to be the best it can be,
    Tesco mommentum is UL made upto 99 ron with additives
    He seems to think that if the Tesco fuel is stored for a period of time ( over 6 weeks) it becomes better than the V power,
    Im not sure Fuel would mature with age like a good wine .

    I alway though that the octane level would reduce if the fuel was left for too long?

    ive used tesco 99 for ages now always feels better after prolonged use.

    A lil test to try. Get some 99 in for a few fill ups then get it nearly empty and try some normal bp fuel and ull see the difference

    Don't use vpower or Tesco but I've been using sainsburys premium fuel as its a lot cheaper and high octane. no problems so far. my SIS put regular fuel in at it felt soo slugish

    I read that Tesco fuel was never very consistent due to the fact that the octane level gets worse the longer it sits in the tank at a petrol station.

    To be fair I dont think you'd ever be able to feel a difference. Have you ever seen any difference on Bill's rollers between Shell and Momentum?

    EDIT, oh and as if it matters what fuel you run when your WMI effective boosts the octane anyway! You might as well run 95 RON.

    According to google maps there is the following road in the US "Skin Creek Road, Lewisville, OH, United States"

    I could feel the difference in my old high compression NA vauxhall 16v motor, so i cant see any reason why you wouldnt be able to feel it on a tuned turbocharged engine where its even more important.

    Knock causes the ECU to retard the timing and reduce requested load, meaning you'll get less boost, less timing and less power. The more tuned an engine is the bigger the difference. I'd bet you'd see a fairly substantial drop in power on a 300hp S3 between 95 and 98 octane fuel.

    edit: doh i just realised you were meaning between tesco 99 and vpower, rather than SUL and Regular!

    :whistle2:

    Plus Welly runs WMI which increases the octane level.

    When I went to the Ring last year I did a lap with VCDS running and measuring ignition timing while on the 103RON stuff they sell out there. On the logs there was hardly any pull compared to on 99RON but I couldn't feel the difference.

    had it been mapped for 102 and you threw 98 in it though, you'd see a lot of pull and distinctly less power.

    I think MRC did a European S4 recently and the 102octane fuel gave about +30hp on a similarly tuned (~500hp) S4 motor.

    Since I've been on a Stage 2 map the car has had nothing but 99 shell or the 103 stuff from Germany. It was mapped for 99.

    Last year when I did the test I was running with an ultra poo map that was running lean and ruined my turbo.

    I use both as I have a Shell Garage and a Tesco Garage both near were I live and the only difference I see is the 12p a litre I save with the Momentum....

    I use Tesco 99,. I get more miles per tank and the car feels nicer to drive.

    I put some regular in not long ago and I could tell the difference.

    Vpower has better qualities than Tesco ie knock reduction as tested by a few tuners. But then does cost more and the rewards arent as great.

    The thorney test linked above seems to suggest the opposite...

    Ofcourse its quite a few years old now, so things may have changed.

    Plus Thorney are sponsored by Tesco :p I mentioned it to Ali who owns Unit18 and he said it was the answer i gave on Vpower being better as carried out by lots of other independant tuners. Dont ask me who as i dont know lol.
