Just because the fuel has ethanol doesn't mean it isn't what it says it is regarding octane. The problem comes from stored fuel either in the ground at the station or in your tank over the summer. If all your fuel comes from a high volume dealer you probably won't have issues. But since snowmobile fuel sources are typically back country places that don't sell much premium fuel except to high output snowmobilers, you may be putting 91 octane fuel in your tank that's 2-3 months old that ain't 91 no-moe. And unless you and 20-30 other affected customers can pull resources for laywers, fuel sample testing, expert testimony, etc, expect to be the lone supplier of repair funds.
Perhaps some enterprising Canuck can perform some random testing on they're fuel. All thats needed is water and a couple measured beekers.
Maybe Ontario is alone in thier mandate but if I lived outside of Ontario I wouldn't assume that the fuel supplier or station owner isn't cutting corners. After all, nearly all trucks/autos and low to mid performance 87 octane burning sleds won't have issues. It's the small minority high output folks like us SRX owners that can suffer.
DCS is great insurance and is perhaps nearly fullproof. But IMO there ain't no such thing as perfection unless you're a 2011 year old jewish carpenter.
We here in the states already know what we're up against. Or at least we know enough to not assume we know. I can't stress enough the need to ignore what the pump says. Whether it's the refinery or the station owner, there is too much incentive to cut corners.
