My bike runs sweet on the 99, but i generally use 97 as standard.
It's not too keen on the 95 and i notice a difference when i use it.

i also got a transit van, the lad i used to carry in the back allways moaned about the smell in the back when i bought diesel from sainbury,s,  i wont put in in my car, or use them for the bike, it,s shit, i use about 200, a week just for the van so not a small user.

i use shell cos the cops dont fill up anywhere else. also a mate races a ktm which doesnt run very well on normal but runs ok on v power. i fill up with normal and use vpower every third tankful. works for me.

Using higher octane fuel than your engine requires actually gives no benefit and may be a waste of money. This is because virtually NO engines require 98 RON over 95, and the market for ‘super’ fuels seems to be based on people’s misunderstanding of octane ratings and the placebo effect of filling up with ‘more powerful’ fuel – making motorists think their engine is running better in some way.What do the fuel companies say then, to justify the “increased power” claims for the super grade fuels? Some companies say that while all fuels contain cleaning additives, ‘super’ fuels contain more or better detergents to keep the injectors cleaner than standard fuel. Others say the fuel is a few percent denser which gives slightly more power per litre. These benefits may be marginal though in comparison to the extra cost involved so it is worth ensuring that your engine will actually benefit before filling up.Some engines actually do need higher octane fuel, such as race engines with very high compression and some turbocharged engines, such as the import version of the Nissan Skyline. Also, a few vehicles, such as the new BMW K1200R motorbike, can sense knock and adjust their engine tuning to take advantage of higher grade fuels. Another user commented that the 2004 BMW 330 also does this, according to the driver’s handbook it makes 231 BHP on 98 octane and 221 BHP on 95. This ability is apparently widespread amongst German performance cars using Bosch / Siemens electronic engine controls.

:agree Unless it's mapped to run on 97+ ron, or intelligent enough to use it properly, it won't have any effect.

Just be glad we don't get the shite 'regular' unleaded from the US.  At 87-91 octane you may well notice a difference with that stuff  :b

i just bought a ford kuga, it says inside the petrol cap only run on high grade fuel, ????

[darrsi]

What's the score with the new V Power Nitro +, is that just all about better cleaning abilities?

Regular unleaded here is high grade.  We get 95 ron, US, Japan etc get 87-91 ish in regular.
Regular here is premium compared to a lot of places.

nice one Lawrence I didn't realise that, Is that the same for diesel, cos it,s actually a turbo diesel.?

I put the cheapest cheapest cheeeappest fuel possible in all my vehicles. Including my E55 (5.4L V8). A higher octane fuel resists pre-ignition, compared to lower octane fuel, that is all! My car will listen for engine knocking, and retard the timing if it does, and the bike is carbed so doesnt matter either way (the listening for knocking is done by me!)

The diesel bike! Now that gets anything! Veg oil, old engine oil, ATF fluid, bit of a petrol. etc etc

That's not quite true
According to http://en.wikipedia.org/wiki/Octane_rating
due to different ways of measuring octane (RON, MON, AKI...)
"... the octane rating shown in Canada and the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel."
