Hi,
Im off to VMAX this weekend and was going to fill up with V-power/High Octane, but was just wondering if its possible to can you find stronger stuff in the UK? ie 98+???
And were can i find it?
Tks
What do you mean stronger stuff?? Octanes have nothing to do with such a thing.Im off to VMAX this weekend and was going to fill up with V-power/High Octane, but was just wondering if its possible to can you find stronger stuff in the UK? ie 98+???

What sort of car do you have? And is it tuned or capable of dynamically remapping for higher octane fuel?
I believe some (few) BP places sell 103 or 104 octane race fuel. Or there are specialist outlets that you can buy race fuel in barrels. Rather expensive though and if your car isn't setup to make the most of it, then you'll see little or no real gains.
I ment stronger as a figure of speech, im not a trained Bio-Chemist so to me higher numbers equals more potent fuel "Stronger stuff".
Im in a tuned C63 AMG, but as to wether it can handle 103 etc im not sure so will check with Kleemann.
If i were to fill up on 103 from BP would i be wasting my time? and does 99 really give any advantage over the standard 95?

You can put higher octane fuel in, it won't do any harm. But it might not make a huge difference.Im in a tuned C63 AMG, but as to wether it can handle 103 etc im not sure so will check with Kleemann.

Is the C63 na or FI? If it's FI and modded I'd have thought it'd need superunleaded.
Higher octane means more stable burn. So less chance of predetonation. This allows you to run a more aggressive state of tune with less risk.

I personally us 98 anyhow, but not sure what you mean by na or FI?Is the C63 na or FI? If it's FI and modded I'd have thought it'd need superunleaded.

I'd just stick to superunleaded, personally I like Tesco 99 or Shell V-Power.I have found most modern cars will run slightly smoother on higher octane fuel and often slightly more economical, so the cost per mile is no different to running 95 RON.
i did not realise that it helped economically,thats good news, i will give it a try on the motorway this weekend.
Thanks

It's not a night and day difference, but I think in most cars it's worth 1-2mpg, maybe a bit more. So in terms of pence per mile it doesn't cost anymore to run.Thanks
But the differences on naturally aspirated engines are normally subtle and minimal in terms of power and delivery.
I do run my TR7 V8 on 99 octane and I certainly think it runs a lot better on, but then it's cammed and has had quite a bit of work done to it.
And turbo powered cars will normally run a lot better on higher octane stuff.
Just to add a bit more.
For VMAX, yes use high octane stuff, although for cost purposes I'd stick to superunleaded grades (97-99 RON) rather than race grades.
This is because most modern cars have a knock sensor, this detects pre-detonation and will retard the timing. This means should you get knock, the ECU will compensate but you'll get less power.
Full power wide open high speed throttle runs (even more so on a hot day) are more inclined to suffer knock than normal pottering about. Even on n/a standard engines.
