What Kind of Gas Do I Run in My Sleds?

What kind of fuel should you run in your snowmobile? Do you need to run premium, or is regular Ok? In this video I'll share what I've learned about Knock, Octane, Ethanol and how they affect which fuel you should run. Not sure what your sled is supposed to use? I'll give you some suggestions about where to look

thanks for another great video

[@smiller3110]

Ethanol is definitely hard on fuel lines and is not good to leave sitting in anything like you said because it absorbs moisture. I notice with chainsaws as well the ethanol eats the primer balls. So its always peace of mind to run premium fuel without ethanol when available. My 2016 F150 w/ 5.0 on the other hand eats on e85 🔥🔥🔥

[@proamateurs4469]

I have a 1997 arctic cat and the manual calls for 87 octane. I decided to fill up with premium one day and to my surprise it actually had notability LESS power. I just found that really interesting and most people I tell don’t believe me when I tell them, lol.

[@MyOldSled]

IMO, the higher octane of premium gas won’t make your sled faster while some guys swear it does. Actually, higher-octane fuels 'technically' have less stored energy than lower-octane fuel. It’s the fuel’s ability to be compressed more without pre-igniting that results in more power overall - Depending on the machine and how it's used. That said, while I believe you, I wouldn't expect it in most cases to be dramatic enough to say "notibly less power"...but there are lots of other factors other than higher octane. Which fuel, what additives, what conditions, engine, etc etc... Thanks for watching and sharing.

[@lakeville1853]

Thank you David

[@worshipguitarnow777]

Thanks for another cool video. Makes me want to get another sled.

[@stevetrepanier4351]

Sled needs 87, gets shell 91 (ethanol free) at the start of every ride. Filling up on a ride it gets whatever is available. In older engines, there is sure to be carbon build up and snowmobile engines are operated at high engine speed for long periods of time. For me, the extra resistance to detonation is worth the extra couple bucks.

[@MyOldSled]

Agree completely. Thanks for sharing your thoughts.

Hey thanks Jon, I appreciate it.

[@SuperBigdanno]

30 yrs of reg fuel, no additive and tank sits wherever it was when I parked it. Clean the carbs every 2 years. I think the reason this works for me is that at the very least 2 times per storage season I dig the sleds out and rip them around the yard a bit. Keeps decent fuel in the carbs and gets the moisture out of the tank and carbs. Worked this long so mot gonna change now. One of the sleds I have Ive owned for 15yrs and it still runs just fine.

I found this as well as other vids very helpful. I did not realize that only shell and Cdn tire sell high test non EtOH gas. I was always of the belief that all the high test stuff had none of it. I had been buying to date PetroCan 94 since its the highest octane and (presumably) no EtOH. Not so. Thanks for this tip The other tip from previous vids that I was recently reminded of was your comment that the Woody's spring tool was a well thought out device. I had in the past used rope and made my own hooked version but the Woody's this weekend saved my sanity and time with all its little nicks and notches. Appreciate all you do on your site.

great video!! I always put regular gasoline in all my machines, small or large unless it recommends higher octane. I always mix Star Tron especially when storing equipment and it never fails. Lawnmower or snowmobile will start on the 1st or 2nd pull. There was an old Marketplace episode on that subject and it was proven that it's a waste of money to get higher premium if manufacturer is not asking for it and it is more pollutant because of the different compression your not actually burning all the fuel.

Your videos also seam so well researched. I have one sled that says 87 and another one that says 91. I have always and will continue to, run ethanol free, no matter what anyone might say, in everything I own that might sit for more than a week or two without running. I don't always have the time to properly store, or maybe don't always expect that this may be my last ride for the year. I live in the north east US salt is used on the roads for snow control. My motorcycle, car, snowmobiles, lawnmowers, snowblower all get ethanol free. So 91 or above

Sea Foam all the way. These other stabilizers( STP, Motormaster, even the Lucas Oil injector and upper cylinder fuel cleaner/stabilizer) they only offer about 6 months of treatment and I have used all the above with my 1998 Ski doo Summit X 670. I am 2nd owner personally put 4000km on in last 3 yrs... mostly toboggan ice fishing/ skimmer for wood. So WORK! It truly has been a GREAT snow machine. But the fuel and stabilizers make a serious difference. I notice power loss with any octane under 87. Idling is rough and top end shake down rides/ spark plugs fouling in 1/2 life. Shell V- Power has best shelf life and noticed equal run and ride to other fuels that I treat with Sea Foam. Sea Foam' s break down video, is accurate and very knowledgeable on why the benefits are unsurpassed! I used 1yr old jerry can gas in 72cc chainsaw, ran perfect. It also does an excellent job at mixing through with gas line antifreeze or other dewatering products. In that worst case scenario.

[@IbocC64]

Vacuum fuel pumps hate ingesting water. Its too viscous, they can't push it through in large amounts. Water separates from the gas in contaminated gas and the gas floats on top of the water as water has a higher density, therefore if you get too much water in will rise above your fuel intake line and you will literally get nothing but water and can contaminate your fuel pump and carbs forcing you to drain the tank and clean the carbs and fuel pump. There are other problems like corrosion and even hydro-lock that can occur when getting too much water in a cylinder and it becomes uncompressible. Then you need to pull the plugs and blow all the water out then change your fuel and clean the fuel system too. It can be a mess. Happened on my 1999 MXZ 600 twice!

[@robandrews4925]

Great video, really important information. My two cents is that based on the rather limited amount of gas you would burn in a season why not give your engine the best fuel possible.

[@MyOldSled]

I agree. Thanks for watching

[@italianbulldog3319]

Bang on Dave!! I've always used premium fuel with no ethanol and Star Tron stabilizer In all my small engine equipment and I've never experienced any fuel related problems. The gas station I buy my fuel from actually state that their premium fuel is ethanol free. Also try to keep tanks topped up to prevent condensation and phase separation. This seems to have happened to my daughter's boyfriends Ski-Doo Renegade on Sunday. We went for our first run of the season on Saturday and he had half a tank of fuel from last year. (Don't know if it was regular fuel or not, he couldn't remember) On Sunday it wouldn't start. After putting the battery booster on and dumping a generous amount of Star Tron in the tank it started. It ran poorly for a while then seemed to clear up and ran fine. He has since topped it up with premium and started it and runs good on the trailer. I may be wrong but it seems that there was a fuel issue and Star Tron to the rescue!

[@MyOldSled]

Yeah most things are ornery when starting up for the first time after sitting. Usually once you run a bit, warm it up and parts get lubricated it wakes up. Thanks for watching.

[@farmark457]

Seems like ethanol gets a bad rap and in some instances maybe so. 5 yrs ago I bought a 1969 pickup truck mostly original including fuel lines and pump and have ran ethanol with no issue’s whatsoever. As a former 30 year mechanic I must conclude maybe the rubber used back then was better or maybe ethanol isn’t as bad as portrayed. I do run regular in my 2020 600 ski do but last tank before storage is premium. Anyway works for me and glad to see you back on you tube. Thx

[@MyOldSled]

There are a lot of variables…so it really depends on a lot of factors. If its allowed to sit indefinitely yes it can phase separate and then you can see issues. I think if a vehicle sits unused to long, it can contribute to a number of processes which degrade components.

[@666dynomax]

Good vid. I run 91 not because of octane and not because its E0 the manyal says 87 10% E is fine, but I don't like that ethanol sitting around for long. 91 here has no ethanol. I run this most of the time in my truck and always in sleds & powertoys. My math on the truck says the 10% (which i think might be even lower) cuts my fuel mileage by about 6%. I faithfully tracked the first 60,000 kms of my tundra in a fuel app... every tank.

[@acemissler6683]

The best octane boost I have found an tested is Lucas oil, and after years of fighting with ethanolI have found what seems to be the only stabilizer that works with ethanol is Ethanol shield, it stops separation of the fuel. I have found it at Peavey Mart. Most stabilizers stop the octane from deteriorating but that's it. Ethanol settles at the bottom after separation and will turn into a black goo if left long enough.

[@MyOldSled]

On a chemical level, most stabilizers are pretty similar in composition … a mixture of antioxidants and lubricants that repel water and limit evaporation. I generally use brp products but I will often grab other brands in a pinch for mowers etc. Really all a Fuel stabilizer does is bond with the gasoline to prevent evaporation. As with anything, evaporation leaves behind a denser liquid ….in gas, Stabilizer prevents fuel from forming sticky resins that can quickly ruin a carburetor. Thanks for watching and commenting.

[@Coyner4321]

Ethanol-free premium in ALL of my small engines.. from my weed eater to jet skis and my sled.. no fuel stabilizer, no line deterioration, no cleaning carbs, etc. Works perfect for me! I'm not an ethanol fan at all. A great additive for treating ethanol-containing gasoline is Star-Tron! 👌🏼 I use that in my old 90 Chevy with regular 87 gasoline.

Diversity is key! The last tank of gas of the season is non-ethanol for storage reasons. If I'm going to fly through the tank of gas on a lawn mower or snowmobile in a day or two, ethanol gas is ok. Clean all your carbs once every two years or so. Its best to run the gas out for storage.

Running a sled out of gas is not recommended, but i do suggest draining carbs for storage. Thanks for watching.

Could you educate all of us with another good video about the use of Methyl Hydrate , or other fuel line anti freeze products or fuel stabilizer ?

[@shperax]

In any snowmobile made mid 90's and on, the metals are designed to be used with ethanol, so it's no big deal. I would just run whatever it says in the manual. Just don't use old gas, and you should be fine. I wouldn't use gas older than 3 months these days. Siphon it out and run it through your car at the end of the riding season. Mix up some seafoam. 1 can of seafoam to only a few liters of gas and run your machine for 10-15 min before you store it. You should never have carb or injector issues again. Note. Seafoam can be mixed up to 50/50.

[@MyOldSled]

Hi shperax. Its actually the rubber and plastic components that are affected by ethanol, and true as early as the 80s they started using materials that were more resistant to ethanol, (inc. modern after market replacements) but it is still harder on them than non-ethanol fuel. This is something that is often debated between those focused primarily on the environment, people in the fossil fuel industry and lots of small engine mechanics. To your point, I agree it's not as disastrous as a lot of people think, but if I can get a non-ethanol fuel, I will always opt for that. As I mention in the video there are a few negatives to ethanol. Thanks for watching and commenting.

[@shperax]

@@MyOldSled Look up the effects of ethanol on aluminum. I've torn apart many engines. Some early aluminum carb, intake and block components look like they get dissolved by acid. That's from Ethanol. Over the years, they have come up with new aluminum compounds that resist ethanol. But yea, it also dries out and shrinks rubber and plastic. Those materials have also been enhanced to resist ethanol.

[@MyOldSled]

Totally hear you. I don’t think most of the issues are catastrophic. I think even in old motors the ethanol is more damaging when its allowed to sit and ends up phase separating. My thinking is with all the conflicting info i hear and read, there are negatives to ethanol, and really the only downside I can see in premium is cost, so I just run premium.

[@davebabbitt2432]

Yes, ethanol is hygroscopic or in other words, attracts water molecules. In the past , motors with carbs and hi/low speed jets would often find the water freezing in the small jet openings causing extreme leaning of the air/fuel mixture resulting in extreme heat, and piston meltdown. I’m not sure how modern day injectors handle this problem but like you suggested, simply avoid ethanol when possible. Another downside to ethanol is that it actually has about 30% less energy than gasoline. No matter how you cut it, if you have ethanol in your tank, there aren’t as many kilojoules of energy available. Can you sense it in the performance of your sled? Perhaps, perhaps not.

[@MyOldSled]

To be honest I think the negative properties listed in the video, were greatly exaggerated when ethanol was first introduced, and a lot of those fears are continued today, including its hygroscopic properties. The layer at the top of the tank can absorb water molecules, but until it is substantial enough to cause phase separation to be honest, I’ve never worried about it too much. A lot of old school guys are more worried than i have been. I did put regular 87 in once and didn’t see a difference, but with my sleds, ridden conservatively the way I tend to, I don’t expect to see any difference. If i had fuel in something for a year, i’d probably drain it. Yes moisture in carbs could cause issues, and can also cause slides to stick. To me its a matter of premium and ethanol free is worry free, and im not buying hundreds of gallons so why not. I use regular gas in the truck.

[@MyOldSled]

Also, yes ethanol has less energy, (and higher octane) than gasoline, but again, a typical rider, running E10, Out for a day on the trail probably wouldn’t really feel a difference. I think sometimes when guys say they do its a but of a placebo effect, but what do I know? :)

[@tylernelson1993]

Here's the thing. You do zip up in the UP and in Canada and in northern Wisconsin and Minnesota.. You are likely to have water in your gas compared to people better in more Southern states.. Illinois gas is way better quality of gas. Same goes for Indiana and Ohio. And a lot of the attitudes that they use in your northern states to keep fuel from freezing also cause it to absorb water.

[@MyOldSled]

Hi Tyler. There is some variance between states, but the typical gasoline blends described in the video apply to most of the us and canada. The component which causes gasoline to attract moisture is ethanol. While not it’s main function, ethanol is also the primary additive which prevents freezing. The majority of Illinois motorists buy gas with a 10% blend of ethanol although the US Environmental Protection Agency issued a waiver to allow the sale of 15% ethanol blend gasoline. Minnesota and Iowa are the top 2 ethanol-blending states by percentage. Minnesota recorded a 12.6% blend rate followed by Iowa at 11.6%. One of my favourite states, Texas ranks third at a 10.7% blending rate, with california is right behind Texas. Thanks for watching and for the interesting comment.

[@pinittowinit8481]

Just my opinion think it's kinda useless IF your sled is STOCK. Me and my dad have ran regular forever everything ran fine. We also go through a tonne of gas so it just doesn't make sense to get premium. But yes run premium if you care that much or if your motor is ridiculously high performance.

[@MyOldSled]

Hi PTWI. Very much depends on the sled you run. Even a stock sled can have a high compression motor rated for a 91 octane. If your stock sled is designed for a 91 octane fuel, you absolutely can damage your motor over time running the wrong fuel. Thanks for watching and commenting.

I buy premium at my esso I didn’t know esso stations didn’t have ethanol and when I bought the sled off my uncle he told me he ran premium so I just continued

[@MyOldSled]

Unfortunately, I think they are switching to ethanol soon. The station near me just informed me today that was supposed to have happened already, and will be soon.

@@MyOldSled Apparently Canadian Tire gas bars will still have Ethanol free 91!

[@MyOldSled]

Thanks James. I did see a post recently about a specific CT that had a 10% ethanol sticker on premium, and I know some stations are switching. Just check the markings on the pumps.

Any chance you will be selling your old sled David? Need a first sled and I am 55 yrs old from Manitoba

[@MyOldSled]

I go back and forth on that. I still have a lot of fun with it. Thats a long way to come for a sled!

@@MyOldSled I have been debating all my life on buying one and eventually need to do at just let me know if you do decide eventually I sold cars for a living and realize it's more about the owner than the vehicle when it comes to buying used if you know what I mean

[@ourkid2000]

Yeah, I just go to the local Esso and get the premium because there's no ethanol.

[@MyOldSled]

good call.

I buy 90 ethanol free..manual says 91..should be ok I would imagine?thanks

[@MyOldSled]

Just like the petroleum industry to make gas one octane number different just to confuse us….:) if it was me I would run it. I can’t see it would hurt.

Costco premium is ethanol free and at a reasonable price.

[@MyOldSled]

Thanks Robert. I am a long way from a Costco :)

[@Wastelessplague]

try to only put ethyl free gas in every thing i own

[@MyOldSled]

Can’t hurt! Thanks for watching.

[@charlesmyers2762]

I won't run Ethanol in any of my sleds. I run 91 minimum....ethanol can actually etch the fuel bowls of older sled...my buddies 96 Formula Z was horrible. Ethenol is the devil unless your fuel system was designed to run it.

[@MyOldSled]

Not a bad thought, unfortunately it's getting harder to find ethanol free fuel and some stations that currently carry it are switching.
