Reading another thread on KB on Octane rating, made me have a quick look at the Workshop manual for the Busa which states (outside of the US), use graded 91 Octane (Research Method) or higher Unleaded gasoline is recommended.

Now, I have ALWAYS used 91 and never really thought about changing to a higher octane rating..

So the short story... What do you guys use and have you tried others?

98 octane
I see no performance or efficiency gain going 1 up.
Significant efficiency gain 2 up.

96/5 octane
I see no performance or efficiency gain going 1 up.
No efficiency gain 2 up and the pipes get sooty.

91 octane
I see efficiency gain going 1 up.
Efficiency loss 2 up and the pipes get sooty.

All on BP because of fuel card.
However on Caltex 91 I get an efficiency gain over all above listed and no soot in either one up or 2 up.

No long term recorded stats to back this up but on the 91 caltex my trip comp always showed 19kmpl going long distance, all bp fuels seem to top out at 15kmpl.

I've tried 91, 95 & 98. I get better economy on the higher octane but the extra price negates it. Hard to tell if power is better as you would have to retune for it to get an advantage.

Thanks for that.. Having a look at the Australian Board, and BP/Vortex 95 seems to be the most commonly used one over there.. Your comment is also re-inforced by a few as well

So do you swap around.. or have you settled on one?
Am off to Napier this weekend, so I will have a play - unless anyone thinks I shouldn't?

Thanks Big Dog.. Extremely helpful

You did not ask me but I'm less than humble....

Ride whatever you already have in the tank (fill it up) record mileage.
run as low as you can and fill with new choice (preferably after already running a tank of the new choice). Ride the same route on the way back or in similar conditions and again record mileage.

Repeat as required. factors such as your size and your load will affect the benefits - as well as what fuel you had in your tank the last time you had a full service or otherwise adjusted your fueling.

98 if its available
95 otherwise.
91 if I have to

On 98
350k out of a tank, cruising at 100kph
260 - 280 touring two up not at 100k
210 - 240ish riding back and forth to work
160k out of a tank with a day spent at the flying quarters

I think you get better economy with your right wrist than your fuel choice.
I haven't ever noticed much difference from one fuel to the next.
But then the tanks not usually totally empty and I haven't ridden exactly the same roads
with exactly the same throttle movements.
I just happen to prefer 98.

When I'm home its always 98BP, when I'm touring its whatever is served
at the petrol station I stop at.

I wouldn't worry about it, put in what you can afford as long as its within the
bikes octane range and it runs alright.

Hi
just brought my '03 out from Aussie and looking for bussa (or anything) riders to ride with
if you sit on 180km plus for 1.5hrs (Aussie roads are fucken straight) fuel doesn't last long
NZ roads are "choice as" 100km speed limits on roads that you are hard pushed to do 80/90km/hr
in Aussie twisty roads have 60km/hr speed limits and they are not that twisty
I'm glad to be home

I know what you mean.. Bought mine back from Sydney, and the Sydney Motorcycle Club was an awesome bunch of people - as well as here before anyone gets started

There are a few rides out and about, so I suggest you keep an eye out on the calendar

Awaiting a ride review by HXC!

Well what can I say? I didn't expect M1CRO's comment yesterday, "You can take the 'Busa out if you want" to be serious. (My bike is in gettin' a camchain done.)

I was kindly offered the use of a FZR400 race bike, and was pretty excited about that, having never ridden a 4cyl before, and never ridden a 'sports bike', nor anything bigger than a 250 either.

So off I go to the trackday today, excited about riding the 400. Which, to be honest, just did everything that the Spada did, but quicker and smoother - not much of a change. I joke about how my leathers don't match the 'Busa so I'll have to steal M1CRO's, and he says it's all about style. Then, in all honesty, word for word..."Nah, you can take it out later if you want. Just take it easy. Why don't you go up and down the pits now?"

I of course, jump at the opportunity. And find myself riding quite happily, this beast, when mum spots me...and I laugh. So after 2-3 minutes of up and down the pits, with pictures being taken, I give him back his trusty steed, to wait until later.

Later comes...wow! Holy shit these things are fast! It's a big bike, but not too noticeable when riding it. I took it easy the first couple of laps, then gently pumped the pace up a bit. Was quite happy doing 220ish down the back straight before braking early, to not frighten myself. I reluctantly pull away from the track as the session ends, only to discover many standing, waiting for my response of "Holy shit, these things are fast!"

Was an absolutely awesome ride, and an opportunity I gladly jumped at, although causing controversy with a few, including parents at first. M1CRO watched me like a hawk as I rode around that track with the biggest grin (thank God for bandanas). So thanks to M1CRO for placing that much trust in me to take his bike out, I know it was probably damn hard to hand the seat over.

Thanks mate.

I don't know....but you can change that siggy (back). It awaits too far in the future to be relevant at this stage of your licence conditions, young man
