Another ride today on the Super. Same as yesterday - pushed it hard and was rewarded with a bike that felt more on steroids than usual and oh so smoooooth! Will use up most of the tank and refill with Regular and give a back to back report.

Swansea can I just confirm

Vpower is 99 ron
Super is 97 and
Regular is 95 right?

Which one you using? 99 or 97. I use the BP garage next to me it has 97 Ron but I might travel the little extra to the shell station and try the Vpower to try for myself if there is a difference.

97. Will try Vpower and see how that compares.

My bike, and previous bikes, have often felt smoother and faster according to atmospheric conditions.
Possibly down to the humidity of air going in to the engine?
I have noticed this, particularly on a cool summer evening, after dark. I never use 'premium' petrol.
Do I imagine this? or have other people noticed?

 Z Pete you are correct cooler air equals denser air which equals more oxygen which results in better burn of fuel result more power  :046:

This is interesting:


5th gear found a small difference in power between different fuels.  But 'feel' is different to outright power.  Few of us ever get to peak power while riding anyway. 

I can believe that it makes a difference.  I do know that years ago my 600 bandit used to develop a massive flatspot if I ever filled up with Asda fuel.

I had a similar effect on my previous BMW with Asda diesel. Every time I used it, it would go into limp mode and I would have to drain it and refill with premium fuel eg shell etc.

That's just because ASDA fuel and most of the super cheap supermarket fuels are also super CRAP!

Standard is 95ron but I wouldn't be surprised if you look hard enough, you'll probably find ASDA and other certain supermarket fuels like Morrisons are less than 95.
Worth noting Tesco use 'Momentum fuels' who are a reputable independent fuel supplier and provide reasonably good fuels

Not sure exactly what it is they do but I know they use the 'left overs' if you will... the slightly less refined stuff and dilute it to make it run.
Worth noting that this is similar abroad where fuel industry is less regulated. ALWAYS buy premium if you ride on the continent!

If you're tempted by the premium stuff then make sure you don't use this one  :008: :008: :008:
