I typically don't run anything. I make sure to get as much fresh fuel in the tank as possible before the first ride of the year. I do run some heet during the season and recently have used the Polaris anti static stuff because I got 12 bottles of it. Always try to have non ethanol in the tank for storage. Can't say I've ever had any major issues.

 

I’ve used these for years and have never had an issue with fuel. They are pricey but it’s a one shot deal and no more looking for additive or stabilizer for storage.

 

I use nothing else but FITCH in all my sleds. I use Stabil in my boat.

 

I could be way wrong but I thought “HEET “ contain methanol not isopropyl that is preferable ?

 

Heet is methanol, ISO-heet is isopropyl alcohol. They say iso is preferred for 2 cycle engines. I've used both and have no issues.

 

bull shit test. you don't run two stroke mix in a 4 stroke motor. and marvel mystery oil does no claim to stabilize fuel they didn't test the three that would blow stabil out of the water? i've had k-100 clean carb's without ever taking stuff apart. but you have to run it on choke for 5-10 minutes for three times. then the snowblower or what ever this was done on ran perfect. try that with stabil.

i do for winterizing marine engines. more on that later. Busy day at work. I’ll explain how, why it works, plus it caught mercruiser’s ear and why they now recommend it.

 

I store my sleds with polaris carbon clean or anti static and a full tank of fuel (ethanol sadly in Canada) and I've never had issues.

 

I work on a lot of carburetors (not many sled carbs) and i’ve found stabil to work real well also. That’s what i use on my and others i work on / winterize/ etc.

 

Don’t want to start a big debate but this is a good point in the conversation to mention the good in using ethanol fuel DURNING THE SEASON when moisture is most likely to accumulate in the fuel tank… ethanol is beneficial here as it combat’s and carries moisture through the system. Not saying at all it’s what you should be running but if using nothing but non ethanol (rec fuel) I’d be adding a tad of isopropyl now and then. I definitely store my sled with non ethanol but I know guys that never use it on or off season with never an issue if stored treated properly with a FULL tank. Just my observation of many decades ..carbureted or into the fuel injection years

 

I agree. Using E10 fuel during the season is totally fine. For summer storage non ethanol is preferred. In the winter where I ride most pumps are 91 non so I use some heet. If the pump has 93E10 I will fill up with that. There also is some argument for a slight performance gain with the E10 fuel.

 

I've been storing my marine fuel with stabil, along with my sled, power washer, and snowblower for decades never having a fuel issue even after 4-5 years.

 

mechanic's in a bottle, BG44k, royal purple max clean and stabilizer.

 

Mib works awesome in some of older power equipment that can sit around more that 2 years.

 

I have a dozen small engines between 10 and 25, maybe 30 years old. They do all get ran at least once or twice a year, and for as long as I can remember (last 15-20 years?) I’ve been storing them with SeaFoam and non ethanol fuel, and a shot of two-stroke oil. I think it must even preserve the gaskets and rubber parts too (think primer bulbs) , as I took a float bowl off a ‘90s generator recently and the bowl gasket would have gone right back in place if I had wanted it too.

 

Looks like im sticking to STA BIL

Great reviews on Ethanol Sheild, its what Ive used in everything 2 stroke for the last year.

 

I started using Star*Tron in my boat years ago and always had good results with it. Definitely easier starts after sitting for awhile. (5.0L MPI) Started using it in the sleds for summer storage. I do partially fill and replace the tanks early in the year, and then again late in the year, and so far, no issues with starting or running. As someone mentioned, I like to get fresh gas in them ASAP once we start riding and take it easy until I'm about 1/2 way empty and refilled again.

 

BTW, why was this posted in the Polaris (Matrix) section? Does this mean other brands don't even need stabilizer?!

 

everything in that video basically just demonstrated how bad modern fuel is and that we are screwed basically. I parked a half ton gas truck for a month two winters ago, maybe 5 weeks. 40k miles on it, and the fuel pump set up during that time. That wouldn’t have happened 10 years ago. It only has the cheap ethanol fuel in it. My error

 

Yep. I just put one of my trucks into storage for the winter yesterday. I ran it down to the fuel light came on, put a bottle of stabil in it, and filled it to the top with 91 non ethanol. Ive been doing this for years and never had a problem in spring.
For good measure I run the truck down to half tank in spring and then fill it back up with 91 non ethanol again.
Ethanol absolutely destroys everything

 

Idk how bad the current fuels really are, sure they all have 10% ethanol, or more blended in them, but I've never had a fuel related issue here.

 

Would just like to know the Fitch being dropped in the tank never would cause any kind of issues with pump pick up and components inside the tank….id give it a try.

 

I’ve used Fitch pucks going back to my Sabercat days and never had an issue in any shape or form. Most sleds to work properly need 2 pucks to do the job properly. Once in the tank I don’t ever buy any additives other than a shot of fuel injector cleaner a few times a season. I leave battery tenders on them and anytime of year I can start them with just the turn of the key.

 

Would just like to know the Fitch being dropped in and moving around the tank bottom would not cause a problem with any fuel pump and pick up components.. I’d try one. Not an easy thing to remove if ya had to..

 

Sorry for the double post… stupid phone.

 

Local business here services the fuel pumps at big chain gas stations. He has shown me pics of how bad some of the pumps and fittings get internally . He’s busy just about 24-7-365. Lot of that is from moisture innthe tanks I’m sure though too

 

Really depends where a sled is stored...if in an enclosed trailer with poor ventilation, you'd better fog the engine well when storing. Even a humid, or damp shed is bad if you don't fog.
