Seems a bit silly, considering it is nothing special yet BP consistently charge at least 3p more than any other garages.
Ive started using VPowah exclusively in my 13 yr old CBR6...it makes a big enough difference to warrant using it - engine runs smoother at idle and under load, defo get more MPG and I do notice the pickup is quicker and more power through the revs/gears.
Next stop new chain and sprockets, going 1 tooth down on the front!

Who's your mapper? I'm pretty sure everyone normally says V-Power is best.
Paul Blamire. The issue is that V-Power goes off much more quickly. If you get new stuff it's great, but if it has been in the garage tank for four weeks, it has dropped its octane rating. Tesco 99 RON either turns over faster, or lasts better. Either way, the octane rating is much more likely to be what is intended. The best V-Power is probably a little better than the best 99 RON, but the average probably works the other way around.
