Thought I'd try V power.

Just to make a bald statement saying what everyone else had said is cobblers, without giving any reasons even for that statement, well, not surprising you'll put someone's back up a bit, is it?

There you go again, I did not say that what everyone else said was cobblers, I did not use the word 'everyone' or infer it, yet another misrepresentation. I said there was 'cobblers being said about these fuels' and there ARE comments that presume these fuels perform better because of a higher RON value -you do not have to be engineer to work out that an anti-knock additive is in a fuel to retard the burn in engines that need it, and patently does not offer any advantage in engines that don't need it (like in a standard jap four for example).
Sorry if I appear arrogant but perhaps I should have mentioned relevent credentials, I was a marine engineer (with a good degree) for 35 years and taught it at City of London Poly for 3 of those years before moving into diving tech. I do know a little bit about engines and the stuff that makes the bits move around inside. I don't know what Shell stick in their fuels but I'd bet the bottom line is that your engine runs just as fine without it.

:thumbup :thumbup :thumbup You have hit the nail on the head.
To some the spoken cold hard truth is considered arrogance. :rolleyes

Each to their own and if they are happy spending well earned cash on a fuel with a higher RON value, then they are entitled to and if they feel there bike runs better on it, then there is no harm in using it.
I remember the old GS Suzukis which were designed to run on low octane unleaded fuel and 2 in the bike club I was a member of insisted on using high octane leaded fuel and could not be convinced that the low octane fuel was perfectly fine. Even when they were changing plugs more frequently than I was due to lead fouling they still remained unconvinced.

Oh! one question, a good degree of what :lol :lol
