How about a which oil is best thread?
Anyway chill out dudes. But meanwhile,
The first thing you have to understand is that high octane as Simon points out simply means a slower more controlled burn. The engine in your Fazer produces optimum performance on 92RON and it's timing is set up for 92RON.
What you might be better doing, rather than umm spending cash on fancy fuels, is looking into ignition advancers. As we can't get 92RON and have to use 95RON, the theory is that you might want to advance the ignition to match the fuel you are using and ensure max performance. ( that could be an angry thread too!
)
Now I have tried super unleaded in my car. Simply becuase the local garage was out of ordinary unleaded and I needed fuel. I noticed no difference. But I can't remember what brand out petrol station is/was selling (it's changed a few times (see how much I care)).
But anyway I will look out for some V power come the spring and try and get a couple of tank fulls, hopefully 2 in a row, through the bike. I am puzzled that people claim to notice a difference. Plus Shell claim more MPG (though they offer no evidence whatsoever. So OK I'll try it and and report back.
All in the head? Placebo effect? Ever heard of God? Some folks even talk to him you know!
Hey, how about a God thread?
