A myth that premium gives better MPG is one of the 7 myths along with buying the cheapest gas around is not as good as the most expensive in town:

And that said, we will each run what we think is best, real world experiences or not (and my Ryker will run on 87, with or without ethanol.) Speaking of "crap I read on the internet..." This thread has more than its share. 48 posts and not one convert from 91 (92) to 87 or vice versa!
So, I was on the Can Am site today looking at Ryker specs. It says Premium Unleaded right on their website under the Ryker specs under the Capacity Section. So, what say you now?
It goes back to Minimum Requirements vs Optimal Options. Yes, you can run ethanol fuel with an octane rating as low as 87 in the Ryker. The ECU is designed to compensate for the less than optimal octane component. But if you want optimal performance you will need to use Premium Octane fuel. And, knowing the attributes of both fuel types. Using non-ethanol fuel will give you the best results. It's simply a matter of physics. You just can't change physical realities with opinions.
However, the next potential fly in the ointment and legitimate question is, how much difference will using optimal fuel make over using the minimum requirement fuel? This is where the factual debate lies.
It will be small and not actually noticeable, really. Not worth the hefty price difference.
I would love to see documentation on this. The physics are there. The rest is speculation and opinion until someone takes the time to do some research. Otherwise, BRP is simply recommending premium fuel to increase the cost of owning a Ryker.
Not saying you're wrong. Just saying...
Some years ago there were several studies on using higher octane. Not being sure what I was reading I was using 91, until I realized it only required 87 on re-reading the manual. The studies basically said using higher octane than required was a waste of money. The Ryker manual is poorly written and vague about several things. I am frugal but not cheap, spending more on gas than I need to is just a waste of money for myself.
And of course each person can make there own decision on what to use. On one trip I got got exceptional mpg, but it was a warm day and I was at a t study 40 mph. I think weather and humidity and winter vs summer gas has a big impact on mpg and not octane. When someone says "optimal" without explaining what it means I tend to ignore it.
:agree:
Does it really? What is the knock sensor Part number?Well, technically yes but in reality, using the higher octane allows the ECM to use a different timing map (more advancement) without detonation. Which will in fact give better performance by accessing all available power the engine has at any given load....
They are not actually recommending premium They are recommending 87, but saying it is "OK" to use premium, just to satisfy every customer.
They would have said to use premium, and that using 87 was "OK", if that was the best way to go.
I’ve seen tests (I’m sure this can be found on YouTube) on the cleaning properties of 87 vs 93 octane and the higher octane gas with the added detergents do clean a good amount better.
