premium petrol types

[Jazzscot]

Today I was out for a blast and had to stop for a refuel (as you do when you own a storm) Anyway, pulled up to the pump and for some reason I was drawn to the middle pump in the group of 3. I usually just fill up with bog standard 95 ron unleaded but today I put some of the premium stuff in http://www.tesco.com/Momentum99/

Now the good bit. I headed for home and by heck she was purring away like a happy kitten. She seemed to be pulling loads better and felt a whole lot better in cruising mode too.

Question: was it me just imagining better performance cause I had put more expensive fuel in ? Or are there definite benefits to using the expensive stuff??

What is the best premium petrol in your opinion and what do you usually fill up with?

I found that the higher octane stuff gave me less vibration. I didn't notice other benefits though. This was confirmed to me when I had to refuel with some independent's fuel which gave a noticeable increase in vibes.

mine runs like a bag of poo on the cheapo 95
maybe cos of the +4 advancer?
definately takes off a hell of a lot quicker too with the good stuff.
tbh it depends who im riding with & where i am.... some country stops dont have 97 and if im on a long bimble like the 400 miler on saturday i put in what i can afford lol....
100 miles worth of the good stuff is like £24+
