So, the fuel light comes on, which on my bike means GET FUEL NOW!!!! The only station I was anywhere near had the premium pump out of service, No midgrade offering so I had to dump in 87 octane regular. I was gentle on the throttle and quite careful so as to not have any knocking. However, I know in many new cars the computer will prevent knocking by readjusting the spark, etc. Is that the case with the 1125R ECM? I'm just curious, I gladly pay the price for premium to get the full performance of the bike, but it would set my mind at ease if the regular is OK. | ||

The 1125 does not have a knock sensor, so it cannot adjust the spark timing. You will be fine with the 87, just take it easy to prevent detonation, and fill up with the higher octane gas next time. | ||

Hi, I know the manual states 95 octane but does any one know if 98 octane (available at Australian gas pumps) will have a positive or negative impact on the engine? My setup is completely stock. | ||

It will have no impact other than your wallet.  | ||

I run 91 since it's specified, and I usually ring mine out pretty good whenever I'm on it. Pulled into a station yesterday that had 87, 89, or 94. That's a big jump from 89 to 94, wallet included. But given 32+ MPG and relatively small tank, the 94 was the only real choice. Can someone please insert a story about how running aviation fuel in their bone stock '72 Nova made it a 12 second car  Mike | ||

Jayz, I can feel a difference in drivability, and get less km per tank going from 98 to 95. James | ||

No story, but in my other vehicles, especially my Chevy Suburban I've run all normal grades, 87, 89, 91, 92, 93 while going on cross-country trips and I've noticed a slight increase in MPG with 91-93. The increase is small and barely pays for the extra cost per gallon but I do like not having to full up quite as often. For my bikes, they are all high-compression so I always use 91+ anyway. | ||

whe are so lucky here in Europe, 95, 97, 98 and 100 octane at the gas station | ||

Easy, just like everything else, the US measures octane differently. Our 93/94 "Super" is about 98 for you. "Regular" gas is 87 for us, 91 for you. http://en.wikipedia.org/wiki/Octane_rating | ||

I am not worried about the amount of octane more about the amount of ethanol.. | ||

Thanks Anakist. I fuelled up with 98 and it felt better. May be placebo effect??? | ||
| Froggy |
Yea same here. I have been thinking of converting my XB to run on E85, that would be awesome! | ||

Jayz. Australian octane rating is the same as Froggy quoted for Europe. US 91 is our 95. I run 98 mostly but if there is only 91 I use that and I can't tell the difference. | ||

and we can also get hold of octane boosters for the seriously high compressioned - heh heh |
