Not entirely on point with this thread, but I did read in our newspaper today that Flarda is considering increasing the ethanol content to 15%. Additionally, there was an article yesterday espousing all the great things about ethanol in our gas. SAY IT AIN'T SO!!!!!!!!!!

Canada uses the same octane ratings as the U.S.
87 regular, 89 midgrade and 91 premium typically.
My area uses upto 10% ethanol on the regular and midgrade fuels, while the 91 premium has no ethanol:

If your bike, car or what ever is set up to use premium and you use 87
the on board computer will retard the timing, So there will be a slight lost of power. If you ride easy you'll won't notice it.
But most test riders don't ride easy, So when your selling bikes,your selling
performance. Fast 0 to 60 and 1/4 mile times sell bikes.

:agree:
I always used 87 because I didn't experience "knock". After reading about the computer adjusting for the anti-knock a while back, I started using 91. Still no knock, but better performance. I tried mid-grade (89) and I didn't find that there was a difference from the 91. So I am using Mid-grade (91) most of the time. The cost (and the difference) is higher here, so I might as well save the two or three dollars per tank and use it to buy more gas or accessories.
Regular is $1.07 a litre ($4.07/US gal)

Premium is $1.20/litre ($4.56/US gal).
That is about $3 per tank more and the US$ is at par with the Cdn$ right now

Forgot to mention that I have a 2008 RS (recommended 87). i would say the higher compression RT would benefit with 89 ir 91 Octane
