Super Unleaded
Discussion
I use v-power or tesco's 99 ron.
Anything else is a waste of money as they seem to charge the same amount for super (97-98 ron) as they do v-power/Tesco's 99ron.
My car gets 30mpg on v-power/tesco's, compared to 25-27mpg on 95 ron (standard fuel) and also runs smoother, picks up sharper etc.
If you compare the percentage increases in mpg against the percentage increase in cost from 95-99ron you can see that it makes no sense for me to run anything else.
I really only use 95 ron if i cant get v-power or 99 ron tescos, and even then i only fill what i need for the journey so i can get back on the good stuff asap.
HTH.

Unless you have over 300bhp it will not make the slightest difference. Anyone who disagrees is dilusional. This has been proved and it is a fact.
Its got f*ck all to do with how much power you have, more to do with whether or not your engine can ascertain and make the most of the extra octane.From what I've heard, Shell V power contains cleaning compounds which are good for your engine and contains more than its competitors, however not every car will receive a performance boost. Cars that are tuned to run on the higher octane fuel will notice a difference.
I fill up with V power now and then due to its cleaning properties and for the most part run normal petrol. The garage is out of the way for me so to get it every time would be an inconvenience. I personally don't find the car anymore responsive but thats not to say it isn't. In any car tuned to use normal petrol, the performance gains will be minimal.

Yeah, that'll be off the advert for erm, Shell V-power then.I fill up with V power now and then due to its cleaning properties and for the most part run normal petrol.

+1It really depends on the engine's ECU. Turbo engines have more complex advance/knock sensors to control boost pressure and so can make use of the extra octane. N/A engines may run a little better but the %age increase in power will be much less.

I've just bought a Golf Mk4 V6 4Motion, and have yet to try it with Super unleaded. Any views on whether it is worth paying extra for Super unleaded? Ie do you get more performance or mpg?

I cant find a better link but it was on 5th gear recently (err well on Dave not 5)Tim

You are a moron, its not a fact. Its got nothing to do with bhp, it makes a difference if your ECU is clever enough and has the appropriate sensors to take advantage of the higher octane by altering the igniton timing and/or turbo boost etc.Just have a look in the manual to see what fuel they recommend
If it's been mapped to 95 octane then you're only getting the benefit of the detergents they put in the fuel to keep your engine healthy
If it's mapped to 97 or 98 (like my Evo is), then make sure you put that in. Typically only forced induction cars (particularly imported ones) have a requirement for higher octane fuel as they have more of a tendency to pre-ignite the fuel
A knock sensor is primarily there to protect the engine against rubbish fuel by pegging back the ignition, you shouldn't rely on it

If the car comes from the factory saying 95 octane or higher your wasting your money putting superunleaded in it because its tuned to run on 95 octane. You will get no power advantage at all.
If however you re map the car, more can be had buy remapping it to run on superunleaded. Then it must be run only on superunleaded or you can damage the engine.
