me i tryed super fuel in my bike and car a few times and well to be honest the only differnce i could tell is when i put it in my bike by mistake (touring 2up) it made it vibrate a little more?

so whats the low down then any one sware by it
more power? better mpg? cleaner plugs even

i mean thare always raving on about it been better for high output motors
and motorbikes probaly have the highest state of tune on the road.

I can feel the differance when i go back to >97 ron in my bike but due to the cost i only put it in once a month or on special occasions like rideouts etc

I only notice it in the mpg, adds a couple on, but nothing going to the cheapest station wouldn't also do. They only premium i'd use is esso energy supreme as it contains detergents to help clean the fuel system.

Use Redex additive, it's better and has more permanent benefits

As you've said already you'll feel the benefits of it more in high state tuned cars,especially in Jap imported cars as their fueling maps are set as such to run on higher octane fuel and when run on 95 ron they run like a bag of poo! and can also do damage to the car over time.

I've never bothered with these fancy fuels and don't believe the hype the fuel companies spout about them.

I've got over 100 bhp, why do I need another 1 or 2 when most of the time its only at 20% throttle anyway.

In my opinion fuel is expensive enough as it is without spending any more for zero benefit.

I used to work for Shell as promotion for 'Super fuel' so learnt a lot about it...

Won't bore you with the details, but if your just filling up occasionally for rideouts etc, you won't feel much difference, but once you are running solely on this, the difference is quite noticable and beneficial... Ask Ferrari.

As Clunk said, we don't often open up, so the top end speed isn't so important as the cleaning agents, better acceleration and MPG (although don't expect better MPG if your testing the better acceleration/top end)

So, yep I swear by it being better, but it doesn't bother me if I pull up to a station without it and have to bung in the cheap stuff.

Can't say I bother much ...... the pefomrance gains could be equally as well gained by eating differently

Oddly enough, I find more of difference with the diesel in the car - it runs much cleaner and smoother on Shell/Esso diesel than it does supermarket (Tesco's) diesel

Personally I think most of it is the placebo effect. Although I'm sure they're good at cleaning your fuel system.

I saw a small article in a bike mag where they ran the same bikes with 95 & 98 fuel back to back on a Dyno....The carb'd bike made an extra 0.5BHP or something very tiny and the FI bike made an extra 1-2BHP which I very much doubt anyone would notice.

Bikes are just not setup to take advantage of the fuel, high performance cars do and adjust to the fuel, so using better fuel will make your car faster.

i used to use it racing but ended up not bothering as it made no differnce to the times, so never bothered, so saved myself some money, proper job!

Since our Tesco started selling super unleaded I've been using it in the bike. I've been told it can make a difference but I'm not sure I've noticed, although I do want to cane it more than usual Like Nick says maybe you need to use it for ages.

But it does make me feel that I'm treating my bike well and better than the car, which gets 95. And I don't use the bike so much so the extra cost is negligable, so why not.

I go for the cheapest everytime as It don't last long !


Age


Although the wife came back the other day complaining that I had made her late for work because I had left the car with the fuel light on, she was upset because in her rush she filled the car up with (this was her words) Bloody Nigel Mansell fuel

in small 2 strokes the difference is very obviuos, we run BP ultimate, or before it was available here a mate thats a trucker would bring back 100 octane V speed from germany.

In the bike no, because as far as I am aware the ignition timing is fixed, so the higher octance fuel (with a greater resistance to detonation) cannot be exploited, so the power will stay the same.

In the car yes, becuase it has knock sensors and will retard the ignition (decreasing power) if I use 'normal' unleaded.

I suspect that it would be fairly easy to set up an injected bike using a power commander to get the most from super, but you would then have to use super all the time.

not all of them. only a few bosh systems use them and thay have a maximum advance set point in the ecu.
the ecu constantly advances the timeing until a knock is picked up by a piezo cristal (knock sensor) generating a small pulse.
the ecu then retards the timing 1o.
then when there is no pulse it is re advanced.
there is a set piont so if the sensor or wireing were to fail.

How about throwing in a spoonful of meths when you fill up.. what happens then...
