8 Ways to Prep Your Snowmobile

Ok, I’m late posting this one but February is our busiest month for snowmobile oil as our customers venture out west betwixt now and the end of March. Some great snow to play in at the moment!

Avid riders are already getting their snowmobiles ready for winter. Soon it’ll be time to hit the trails or take to the mountains for the first ride of the season. Nothing ruins a ride more than a breakdown, so we put together some tips to help you get your snowmobile ready for winter.

Check the spark plugs

Inspect spark-plug and wire condition. Ski-Doo E-TEC engines require indexing if removed or replaced, so be sure to check your owner’s manual for proper instructions. They must be set facing the right direction and depth. Replace plugs that appear excessively dirty or worn along with any worn or frayed wires.

Inspect clutches and suspension

Check clutches, the drive belt and suspension for wear and tear. Greasing (everyone always forgets!) and inspecting the suspension components and slides (hyfax) are a great idea. Slides typically have a small line across them indicating when they are worn out. If they are below the line at all, replace them.

Items to check in the suspension include loose or worn parts and missing or loose idler wheels. Inspecting and cleaning the clutches and belt are also a necessary maintenance item. Remove any belt dust or rubber from the clutch sheaves.

Adjust track and check skis

Check your track for proper tension and make sure bolts are tight. Look for worn or missing lugs.

Don’t be that guy (or gal) who everyone has to bail out of trouble at every apex.

On the skis, look for any gouges, cuts or corrosion and make sure the runners are straight and still have carbide on them. The carbide edge allows the skis to bite into the trail and turn better.

Let there be light

Make sure your electrical system is up to par. Inspect the ignition and look for any warning lights that can signal problems. Check high/low-beam headlights and brake lights to ensure the bulbs haven’t burnt out.

Check the oil and filter

If you’re riding a four-stroke and didn’t do it last spring, change the oil and filter.

On two-strokes, make sure to top-off the oil reservoir and use an oil with excellent cold-flow properties for best protection. Inspect the exhaust power valves and clean them if needed. If your power valves are sticking, switch to a high-quality two-stroke oil proven to prevent power-valve sticking, like AMSOIL INTERCEPTOR Synthetic 2-Stroke Oil.

Inspect the fuel system

Check the fuel tank along with the fuel and oil lines for cracks or leaks. Unless you used a stabilizer such as A MSOIL Gasoline Stabilizer, empty the fuel tank and replace with fresh fuel. Clean your carburetor and make sure it’s adjusted properly to prevent performance issues or breakdowns. AMSOIL Power Foam is excellent for cleaning carbs.

Change the chaincase oil

It’s best to change chaincase oil annually, preferably in spring after riding season is over. Chains and gears create metal particles that need to be removed from the fluid regularly lest they build-up and cause bigger problems down the trail. We have just the oil for this important step: AMSOIL Synthetic Chaincase & Gear Oil.

Get there and be prepared

If using a trailer, ensure everything is good to go. Before you load up, inspect the tires, bearings, hitch, safety chains, axle, springs, bed, cover, lights and electrical components.

Prepare for emergencies

Anything can happen, so be prepared. When getting your snowmobile ready for winter, it’s always a good idea to bring fire-starting materials, like a lighter, along with dry clothes, work gloves, water, an extra two strap, granola bars, lip balm and any other essentials you deem necessary to have on hand if you end up stranded.

What Happens to oil Making Me Needing to Change It?

Regardless of its quality, every motor oil eventually loses its potency and must be changed to ensure peak engine protection. Let’s take a look at what happens to motor oil over time and why you periodically need to change oil.

Losing the base

Base oils are the backbone of the finished lubricant that ends up in your engine. Over time, they lose effectiveness due to the following factors:

Oxidation

The interaction between oxygen molecules and motor oil molecules naturally leads to chemical breakdown.

Just as oxygen causes a cut apple to brown or exposed metal to rust, it breaks down base oils and reduces motor oil’s effectiveness.

Oxidation can lead to increased oil viscosity, which negatively affects energy efficiency. It also causes the formation of harmful deposits and sludge.

High heat

Today’s engines run hotter than ever before, with temperatures up to 235°F (113ºC), and even higher if towing or hauling.

The rate of oxidation for oil doubles for every 18°F (10°C) increase in temperature.

Moisture

Your vehicle is subjected to temperature swings, even when it is parked in the garage.

Those temperature swings cause condensation to form inside your engine, leading to water contamination.

Leaving a vehicle parked for extended periods or taking short trips that don’t allow the engine to fully warm up allow water to remain in the oil rather than evaporating and exiting through the tailpipe. Water can lead to formation of sludge…yet another reason why you must change oil.

Viscosity is a motor oil’s most important property. The lower the viscosity, the faster the oils flows, like water. Thicker oils flow more slowly, like honey.

Viscosity loss

A lubricant’s viscosity is its most important property.

Viscosity has a direct bearing on wear protection, and your engine is designed to operate best using a motor oil of a specific viscosity (e.g. 5W-30).

The intense pressure the oil bears as it’s squeezed between moving parts, like the piston ring/cylinder wall interface, can tear apart, or shear, its molecular structure, leading to viscosity loss.

Suddenly, the 5W-30 motor oil your engine was designed to use is now essentially a 5W-20 oil, and wear protection may be compromised. When this happens, it’s time to change your oil.

Fuel dilution

Fuel can wash past the piston rings and contaminate the motor oil, causing it to lose viscosity.

Frequent short trips that don’t allow the oil to reach normal operating temperature can be especially problematic because the fuel won’t volatilize and exit through the PCV system.

Excessive fuel dilution leads to sludge and varnish, requiring you to change oil more frequently.

Additives: Additives are added to base oils to reduce destructive processes and enhance beneficial properties.

For example, antioxidant additives help slow the rate of oxidation. Detergency additives help prevent deposits and sludge while cleaning pre-existing deposits. Formulators add anti-wear additives to some lubricants to form a sacrificial barrier on metal components and help prevent wear.

Since they’re sacrificial in nature, additive depletion is one of the primary reasons motor oil loses its effectiveness and must be changed.

While AMSOIL synthetic motor oil gives you the convenience of fitting oil changes into your schedule, it remains vital to install fresh oil at the appropriate time.
