If you’ve owned a snowmobile for several years (decades even), these summer snowmobile storage tips may come as second nature for you. However, if you are new to snowmobile ownership, most of these steps will be brand-new information. For example, have you ever heard of the term “fogging your engine”?
Some of you may be scratching your head, wondering how to use a fuel stabilizer, or debating between different snowmobile waxes–but fear not!
We’ll walk you through 11 essential snowmobile storage tips and some great pro tips from snowmobilers who have been doing this for years.
Start next year’s snowmobiling season off strong by preparing it for storage (the right way). Thought snowmobile storage was as simple as parking your vehicle in the garage and waiting for winter? Think again.
Phase 1: Use Stabilizers And Fill The Fuel Tank
Fuel stabilizers aren’t just fancy additives. They maintain fuel quality over long periods and protect engine parts from corrosion. More so than with other vehicles, you won’t want to forget the fuel stabilizer when storing a snowmobile for the off-season, given the ethanol-blend fuel used in the fuel system. Otherwise, you may wake up that first morning of snowfall to find that your snowmobile’s engine has been compromised (which means you’ll need to delay your first excursion just to handle repairs).
Need a product recommendation? AMSOIL Gasoline Stabilizer is a high-quality fuel stabilizer that guards against corrosion and fights oxidation.
Another pro tip for new snowmobilers: don’t forget to keep a full tank of gas when storing. A full tank reduces the risk of condensation, which could lead to water in the fuel system. It also prevents the gas gauge float and fuel system seals from drying out.
Many first-time snowmobile owners [wrongfully] think it’s important to empty the tank before the end of the season, but that’s just not the case.
Phase 2: Clean and Wax Your Snowmobile
Proper cleaning of the snowmobile will lead to less rust and corrosion.
Put the snowmobile on a flat, level surface, ensuring the engine is off before beginning the cleaning process.
Use warm, soapy water, grease-cutting cleaner, and engine degreaser like this one, rinsing thoroughly to remove dirt and salt that might corrode metal parts.
Be smart about using powerful cleaning tools like a power washer. They can damage the exterior finish and allow water to penetrate the suspension components and electrical connectors.
After washing, dry the sled with a lint-free towel and allow it to air dry completely before applying a protective polish/wax to give it a good shine. A good snowmobile polish/wax is the Maxima SC1 Clear Coat.
Phase 3: Prepare The Engine for Storage
Engine maintenance is another key aspect of the summer snowmobile storage process. This phase includes several steps:
- Fogging the engine
- Changing oil
- Inspecting power valves
- Maintaining chaincase oil
For the specifics of each of these steps, make sure to check your owner’s manual.
Tips for Fogging the Engine
Fogging the engine involves coating the cylinders and pistons with fogging oil (like this one), safeguarding them against corrosion and piston skirt scouring.
This is crucial if you don’t plan to start your snowmobile’s engine throughout the summer (which is a recommended precaution against engine failure, unwanted moisture exposure, and corrosion.
You can access the engine’s internal parts by removing the airbox and foam or air horns. With the engine running, spray the fogging oil into each intake stroke or directly into the cylinders after the spark plugs are removed.

Chaincase Oil Maintenance
Chaincase oil should be changed annually to ensure adequate lubrication of the chain and sprocket.
Check the chaincase oil for a milky appearance and metal particles, which indicate if maintenance is needed.
Using XPS Synthetic Chaincase Oil, which is formulated specifically for snowmobiles, makes this process much easier. Synthetic chaincase oil is likely recommended in the owner’s manual, but always double-check, just to be sure.
Power Valve Inspection
Power Valve inspections prevent performance degradation and maintain optimal engine efficiency. Before inspecting power valves, ensure the engine is cool and remove any components obstructing access to the valves.
Next, clean the power valves by eliminating carbon deposits. While you are at it, check for signs of wear or damage.
Here’s a pro tip for this one: If you take anything apart during this process, video yourself doing it. That way, you’ll have clear, visual instructions on how to put it back together before storing the snowmobile in its final summer resting place.
Phase 4: Battery Removal
Before removing the snowmobile battery, follow these steps:
- Switch off all electronic systems to prevent short-circuiting
- Disconnect the snowmobile battery starting with the negative terminal, followed by the positive terminal to avoid electrical hazards.
- Remove the battery from the snowmobile for summer storage.
Store the battery in a safe, temperature-controlled environment and use a battery tender or trickle charger to maintain its charge during storage.
While working on the battery, double-check the drive belt. Look for defects or loose cords, and clean the clutch sheaves if necessary before storage.
Phase 5: Lubricate and Grease
Greasing key points on the snowmobile is critical to help prevent rust and corrosion during long-term storage. Focus on greasing the following key areas:
- Steering components
- Front and rear suspensions
- Driveshafts
- Areas around the base of suspension arms and ski spindles.
While doing this, take time to inspect the rear suspension, wells bearing, track, and sliders for any signs of wear or damage. Then, use a spray metal protectant like WD-40 or XPS Suspension Grease for lubrication and rust protection.
Phase 6: Cover Your Snowmobile
After all the cleaning, oiling, and maintenance, you’ll want to make sure you cover the snowmobile properly. Raise the snowmobile off the ground using dollies or blocks to prevent suspension compression.
Typically, a soft, lightweight, fitted cover is recommended to protect the snowmobile. A breathable snowmobile cover helps mitigate moisture build-up and protects against harmful substances, dust, and pests.
Phase 7: Choose the Right Storage Location
Snowmobiles should be stored in a dry indoor location, like a home garage or shed, to reduce risks from humidity and moisture.
However, not everyone has the luxury of owning a climate-controlled garage or shed. If you don’t have room for snowmobile summer storage, consider renting space locally through Neighbor (preferably in your own neighborhood). That way, you can stop in and check on things like the snowmobile’s oil, remaining fuel, and battery health.
In your storage space, it’s also great to have space for things like your snowmobile helmet and other gear.
Monthly Maintenance Routines
Even after all these steps, your monthly maintenance routines while your snowmobile is stored can make all the difference and even help save you money on insurance premiums. Here are a few things to check on until your sled is ready for next winter:
- Checking the fuel and oil levels
- Inspecting the spark plugs and replacing them if necessary
- Lubricate the moving parts
- Check the battery and charge it if needed
- Clean the snowmobile and remove any debris or dirt
- Check the track tension and adjust it if necessary
- Use rodent repellent such as driver sheets or mothballs to keep critters from starting a nest
Summary
Owning a snowmobile is a great (unconventional) way to get outside. However, if summer storage is not handled properly, you’ll miss out on adventure time and have to spend those hours attending to repairs.
If your season is over or you are in between trips, you’ll need to decide where to store your snowmobile for the long term. Neighbor, a peer-to-peer vehicle storage marketplace, is a perfect place to find affordable and convenient snowmobile storage.
