That's enough to insure isn't it? You guys will have these things hoped up before ya know it and be doing scary stuff no worries! Wanna feel silly about the debate go watch a 80's 90's snowmobile movie lol

Cause most people don’t pay close enough attention to what they are doing. Plus most don’t understand EBC. They grab 91 but don’t pay attention if it’s ethanol or not. They fill from some sketchy station in BFE. Tankers go out fill with crap, empty and then put good fuel on, the crap gets into good fuel.
1000 ways to get bad fuel. They cover it with some race or av. People need to pay attention and fill consistently. Just because it’s pump doesn’t mean dump sewer water in it.
I try to fill from the same places. Even go as far as hauling a drum of 91 when we head out.

Maybe I am giving people too much credit. But I really don’t think people paying over 20K for factory turbos are the type to get crap gas. I would guess all of them get non eth 91. I would think anyone getting newer sleds knows how to get gas.

I live in CA and good luck getting ethanol free gas. I wish that was an option for me. I know how bad the ethanol is for 2 stroke motors. Or so Ive been told my entire life. I did have "moderate detonation detected" on my first few rides with my boost. I did add a couple quarts of 100LL the last few rides and never saw the detonation warning. I think that is better to do then seeing the warning coming across my screen? I too only put fresh gas from the local chevron in my sled when riding.
My dealer Boost 23000 O.T.D. ?
19,800 OTD 165 boost pro with electric start.
Basic shocks.
It’s Alaska so no tax.

ever fill at a three way pump 85,87 ethanol and the sign says 91 no ethanol but comes from the same hose. I haul all my sled gas because of this. polaris will have warranty claims because of bad gas but will they pay?????

No one has ever blown a motor from the amount of gas in the line at a 3 way pump… vastly overthinking it.
And any decent station has inline filters/water separators. The chance of getting “bad gas” from a high volume, premium brand station is extremely small.
I owned a gas station for years, went through a few b-trains per week and never poured 1 bad tank or had 1 legit complaint of fuel quality. Only legit gas beef is that it doesn’t last as long as it used to…but that’s only a problem at the consumer level, as it’s never at the station long enough to even remotely be an issue.

I always start by topping off my gas truck with 91, either til full or with a couple gallons, just to clear the line of previous lower octane. Then I fill my sled and/or jugs with what's hopefully 100% 91 non ethanol.
It's going to be hard for polaris to deny claims because of bad gas...
Hard to if you run a diesel
Typical owner would say that putting extra money in your pocket.
I just always filled my buddy's sled first.
Very true that. Even a little boost can bring on detonation if the tuning is off, but at elevation especially, you can tune more power on pump gas safely to a point. The best way to handle significant boost is to redesign the combustion chamber (both piston and cylinder head) to be more resistant to detonation. That partly involves lowering compression, but the most simplistic ways of doing it (a spacer and/or piston changes) loses a lot of efficiency for the amount of detonation resistance it adds, and can even be ineffective in some cases. 2t vs 4t isn't apples to apples, but combustion characteristics do translate, and what early adopters who tinkered with turbos on old American iron found was that the low-compression "emissions" heads were often MORE likely to detonate than closed-chamber heads, despite the drop in compression. So blindly adding CC volume isn't wise, but I'm pretty sure there's more going on with the CC on the Boost head than more volume. For the aftermarket guys, at some point you're either limited to lower boost or more octane, but octane should never be an automatic. It's a convenient band-aid, and that's why you sometimes get blanket recommendations, but a good tuner can make power without it.
Going back to the Boost, I'd lean to the side of "quit worrying about gas." Make sure you're following the manual's fuel requirements to a T, and if something goes wrong, that's what the warranty is for. If you're doing everything right and getting det warnings, raise a stink with your dealer - there's something that needs to be addressed. At that point, it'd be wise to add more octane, just to avoid a break-downs and potentially having your sled sit while it waits for parts. But it's definitely BS to have to run high-octane on a "pump gas" turbo. If that's cropping up, either it's an isolated problem with a few sleds or there are issues with the tune, in which case owners may be back to another round of "flash-dance" fever. If you're following Polaris's guidance on fuel and it's running fine though, I'd suggest you relax, don't worry, and have a home-brew.

Hippie fuel bro! It’s the only way to go! My sleds love sipping on the green fuel, ethonol is of the big bad government, that has stock in rubber fuel hoses and new Poo Boosts man!

Yup I have. And I bet that whole hose full of 85 or whatever the low octane is at the pump really isn’t gonna wreck my day. Oh wait it never has. About 10 years deep with no issues. Crazy! Stop worrying about the gas and go ride!

Hey, keep all that positive stuff to yourself
That’s why I don’t run a pump gas sled. Leaves to much performance on the table for me its good to be right on the edge.
Just to clear one thing up. I have a Boost coming (supposedly) and will not be running any sort of higher octane gas in it unless I decide I need to do some kind of bottom end build (eg, build the sled for better bottom end with a head/flash swap) which I highly doubt I'll attempt. New career + life is busier = I don't want to play pretend "monster-garage" anymore.
The sled is designed around 91 non-eth. It will run that stuff just fine. a hose-worth of 85 isn't going to effect **** (I can do the basic math if you want, but it'd reduce the octane by 0.01% or something)
Only disclaimer, if you have ethanol in the fuel, maybe some race/AV would be a good idea, but then again ethanol sucks because it leans out the fuel (and attracts water) not because it is somehow "lower octane" (there is less net energy in a gallon of ethanol fuel than ethanol free fuel - hence "leaner")
