V-Power / Super Unleaded

Is it worth running the bike on higher octane fuel?
Will it make any difference to the performance?
What are you guys filling up with?

In short, no. I use standard.

Use the more expensive stuff every now and again. Only to give the bike a treat, don't make much difference IMO. I usually fill it up with Vpower etc when they've been stood a while, don't know why, perhaps I'm tricking myself into thinking it will help it along its way after leaving them with half a tank of crap for a month or two

Someone tell me if I'm wrong, but I belive it makes no differnce to injected bikes ie the one you and I own. I have been using regular unleaded all winter with no problems, but then I do my bike in the garage. However if it does then I will put some in.

You need a knock sensor, the new BMW's and Scoobies have them. SV's don't.
Though there are a lot of cleaners and other things in the fuels so they burn better, and even helps with carb icing so you do get a better tank range but it all balances out with the additional cost. I found that Shell Optimax was the best for cost and benifits, the BP stuff was just stupid expensive and didn't compare as well.
If your really bored there is a hole load of it on my blog from the testing I did.

some bikes tend to run better, but only because the higher octane fuel is slightly cleaner than the normal one.

yes and maybe/no.

yes for my bmwr1100s (or for any of the bmw BOXER bikes) id not use anything BUT super unleaded. it really does make a difference!

maybe/no as it varies dependant on bikes, some run better with it, some it barely noticable.. others u may has well of not bothered.

i normally give any bike that is new to me a test (a few successive tankfulls of the good stuff~ to run it through the system) and go from there.

My experience of it in my K4 was that I got marginally higher MPG from it, but the difference was so slight it was nowhere near worth the extra cash. The "backside dyno" noticed no increase in BHP.

Not really, I have never noticed any gains in mpg or power with a tuned or standard SV650 engine.

Any unleaded I can find, and the cheapest too.

i've no scientific evidence to back up my claims, but my curvy seems to suffer less from carb icing when it's filled with super unleaded.
