Our 'Race Fuel' is Shell V-power

not sure of its benifits totaly someone will probably set you right on that
of more help i think deamon tweeks sell it tho

Rather than use race fuel which is very expensive, you would be better using an octane booster. Try using a quality fuel like shell optimax ( its called soemthing different now, but you'll know it as it's more expensive than unleaded) and add a booster like silolene pro boost or aldons equilalent. I've used it in race engines where there is a definate improvement, however, it depends on the machine work done on your engin e.g decked block and skimmed head etc to increase compression. Using with a standard engine won't make a noticeable difference.

Unless your engine is specifically mapped to use it, there's no performance advantage to using high octane fuel (even bog standard Super Unleaded / Optimax etc).

dont BP do 102 octane fuel?

Agreed unless you are running a turbo when higher octane will help with detonation issues. Otherwise, save your money and fill with standard unleaded!

You only release the potential of higher octane fuel with a higher compression ratio.
If you have modded your engine and get detonation then go up a couple of RON values.
