100 Octane

**Acid** · 22nd February 2006, 15:07

heyas was just wondering how many peoples have tried using the wynns octane boost that takes 96 up to 100 and works out costing less than 98.
any replies would be great cause am thinking of using it.

Don't waste your money mate you won't notice any difference.

I could run mine on diesel and it won't make any difference, piece of crap Honda's!.

Plenty of threads about octane etc. Consensus seems to be "No difference unless you make changes to the state of tune".

yeah, wouldn't really be worth it.

91 is cut with more additives than 95/98. Once they're in the bike, you can't take them out, so adding 'octane' isn't going to cure the fact that you could have crap fuel in there. You could use 108 octane (AvGas) and add the octane boost to it, and it'll probably run really really crap..

Unless the engine has been modified to run high octane stuff, the additive stuff doesn't really do anything, the pump stuff works just fine. I can't even tell between most of it, I don't know what all the hype is

You either need high compression or very advanced ignition timing to make any use of high octane fuels.
In some cases high octane actually hinders performance if the motor is not tuned for it.
High octane = lower flammability (ie burns slower).

thanks for answers and nice choice of bike slimjen thatll be what i want later on

buggie sorry mate its the 95 thats got the most additives.

**nadroj** · 22nd February 2006, 15:32

Best mix is 60% 91 octane & 40% 95/98 octane according to a local dyno operator tuning race engines limited to pump gas. Have tried av gas and octane booster in the past but unless you require the higher octane due to compression ratio then you're wasting your time.

k, ma bad. I thought the fuel came pure and they cut it back with additives, which lowered the octane rating

i'll shut up then!

Some bikes do prefer a high octane rating. I've noticed on mine that it has a slight pause when snapping the throttle open on 95 but doesn't do it on 98. Seem to get better milage on 98 too.
