98 octane fuels?

[Kendog]

im amused tho i can get top speed **blush** of 130 red lining of course on 95 octane but the 98 puts my top speed **more blushing** at 140
not that i speed or anything im a legal rider

I am sure these 'tests' were conducted on a track so no worries.

I took my FXR onto Manfeild years ago and it was reading 150 down the back straight using 91.

i am curious as how you managed to get such speed out of it even after a good full on service it only pulls 140 struggling and shaking as only the FXR does.

The bike would have been fairly new (maybe 2 yrs old) and had a very gentle life.
Not sure what the wind was doing that day but a tail wind would have helped, especially on these bikes.

To be honest the FXR does the job well enough on the open road (except passing up hill into a head wind) so I would not worry about 140 vs 150.

Once you get onto a bigger bike you will laugh when thinking back to these speeds being fast. Just remember the road is not a track.

with a teacher like big dog i know when it is time to go fast and slow i dont like to speed that often as its ment for the track! but still sometimes id like to keep up! but will be trading up to my next bike in a matter of weeks but dont know what to get yet any suggestions?

[Pancakes]

I used to run mine on 98 only, have used race gas too but not much octane/$ really eh. Use 95 all the time now and seat'o'the pants meter says no difference from 98 and cheaper. The manual for said mighty Ho'sack says min 86 octane or something stupid! I want a turbo diesel single 250. When I win lotto I'm into production! (hehehe, won't hold ma breath!)

Thats another thread right there.

Not knowing anything about your riding style, size, bike preferences etc it's impossible to recommend a next bike for you. Some advice I can give is to test ride as many bikes as you can, it's the best way to find a bike that is right for you.

This was discussed a while back, and quite a few engineerig types got on board and gave some details as to the determinants of whether higher octan fuels would benefit different engine types / bikes. I seem to remember that it was not recommended for certain bike types.
Also there was some discussion as to the real as opposed to marked ron or octane ratings at different garages.

As for me, 98 is hard to get but I run the GSX on 95. The cage - a 2L v6 sucks in 91 and hardly moves, but the higher the octane the better the performance AND economy.

[Bass]

I run the sprint on the highest octane fuel that I can get at the time.
It detests 91 and behaves accordingly.

i will be testing race gas in the FXR this weekend thanks to one of my buddies here is hoping high octane doesnt let me down

[Grub]

I maintain records of every fill in the '90 and get 98 when I can.

the results are that 98 gives me 1 km per litre better economy and the costs work out the same as 91 or 95.

Therefore 98 is better as it runs cleaner and better

[Kwaka14]

Is the 98 Octane sold in NZ a true 98 octane ie. Ron+Mon readings /2? this is the Octane rating that[B] most manufacturers specify. Usually the advertised rating on Pumps (definitely when I've seen it in Northland) is the RON reading which is typically a few points hicgher than MON. The 12 is supposed to be fine on 91 octane but it pinks badly on NZ 91 as it's actually more like 89 i've been told so I always use 98 or as close to as I can get. It definitely is better for me as I don't get problems with preignition.

98 octane is more effective in high performing vehicles although it wont hurt anything it burns best in these. Its cool to go up in octane i.e 91 to 95 to 96or 98 however going down in octane is not normally recomended (yea i know ).
As mentioned some bikes will run better, smoother, further etc with 98 but others wont even notice the diff as 98 burns cooler so high compession engins may notice more fuel economy. Low compression engins may burn cleaner under heavy loads....Let me know if someone knows more or different
Even though i get discounted fuel i still run my Bike and Cage on 91...some times i will run 98 (in the cage) just to clean pipes and injecters a little more.
FYI: 91 & 98 do not mix to make 95 or 96. 98 will float above 91 (as far as i am awear i could be wrong)

[dangerous]

Its not just about Oct rating... down here we can only get 98 from BP, unlike all other fuels its NOT NZ made ie: shitest crap fuel money can buy... but Aussie made and modified for NZ ie: its a far superior fuel and thats the main reason most engines prefer it.
Remember Chalange? 100% imported and a much all round beter fuel than the shit here.

If ya want to go one beter use AvGas (not legel on the rd) ok so in the average engine theres no more HP infact you can often get a lesser Hp reading, but a beter start, beter idle, smother power etc, its about quality and NZ fuels sure as hell have none of that.

That's because although the group (Todds) that owned Challenge had the biggest single shareholding of the Marsden Point Oil Refinery (27%?), the "Gang of Four" got together and voted to stop them using fuel from the refinery, so they had to import it all, or buy it from the other companies at a hiked-up rate. Eventually they gave up and sold Challenge to Caltex.

Av gas is illegal on the road because it is leaded, but we are happy to have it spread by air all over the landscape aren't we.
Challenge imported their petrol from Singapore, octane was generally higher than stated, but a few tests indicated some batches had substandard additives for protection & easy starting, but quality still good.
