My Personal Recommendation

Some of the most popular snowmobile brands are Polaris, Arctic Cat, Yamaha, and Ski-Doo. And, their engines are different from each other. So, you should buy chaincase oil specifically designed for their engines.

Ski-Doo Chaincase Oil

If you own a Ski-Doo Snowmobile, then you should definitely buy Ski-Doo XPS 2-Stroke Synthetic Oil.

Developed explicitly for high-performance Ski-Doo models, this oil is made with additives that shield internal parts from damage and corrosion.

Ski-Doo chaincase oil is a superior quality lubricant that also conditions seals and delivers excellent performance even in extreme conditions.

It is so highly recommended because of its unique full-synthetic multigrade formulation, which works well in cold temperatures and doesn’t break down in high temperatures.

In a nutshell, if you are searching for an affordable and high-performance chaincase oil for your Ski-Doo snowmobile, then this one is for you.

However, please remember that this oil cannot be used in 2-speed snowmobile transmissions on Expedition and Skandic utility models.

Polaris Chaincase Oil

In my opinion, the best oil for Polaris SCL – Synthetic Chaincase Lubricant.

This high-viscosity formula of this full synthetic Polaris Chaincase Oil provides excellent film strength that you want.

This oil also provides maximum protection to the chains and sprockets.

This Polaris Synthetic Chaincase Oil not only provides lubrication to your snowmobile parts but also protects them from wear.

This oil is very affordable but of high-quality at the same time.

So, if you own a Polaris Snowmobile, I’ll recommend you should buy only this lubricant.

Yamaha Chaincase Oil

If you ride a Yamaha Snowmobile, then you should definitely buy Yamalube Snowmobile Chain Case Lube.

This is a premium quality lubricant that is designed to meet the extreme temperatures and conditions faced by the snowmobiles.

As the Yamaha engines are different from other snowmobiles, so, it’s recommended to use only Yamaha Chaincase Lubricant.

Arctic Cat Chain Case Oil

If you ride Arctic Cat snowmobiles, then you should go for Arctic Cat OEM Chaincase Lubricant.

This is a tried and tested lubricant by many Arctic Cat owners and they loved it.

It’s specially formulated to give protection against wear, corrosion during the time when you are not using your snowmobile like in summers.

It also delivers optimum performance in extreme temperatures.

What is Snowmobile Chaincase Oil?

Snowmobiles have a chaincase, or otherwise known as gear case that holds gears and chains. It is usually covered with a chaincase cover to protect the gears and chains from getting damaged by the snow while driving.

For your snowmobile to run smoothly, your gears and chains must be actively working. Chaincase oil is simply a lubricant that keeps your snowmobile gears and chains smooth and running without any problems.

It is essential to change the chaincase oil every season because of mainly two reasons. The first reason is that the chaincase oil breaks down with continuous heating and cooling cycles, and the second reason is that the chaincase oil can get contaminated by both water and metal slivers from the chain and sprocket.

Therefore, changing the chaincase oil is very important. In simple words, if you have a clean and well-lubed chain, then your snowmobile will perform well, otherwise, it is susceptible to many running problems.

There are plenty of chaincase oil brands available in the market. Some people even use automatic transmission fluid or gear lube to reduce initial costs. However, neither of these fluids is designed to work as chaincase oil.

The automatic transmission fluid leaves chain and gears vulnerable to premature failure, while the automatic gear lube can cause wear and decrease energy efficiency. Given below are the best chaincase oil options that one can use to ensure the smooth and problem-free running of their snowmobiles.

AMSOIL Synthetic Chaincase and Gear Oil

Synthetic chaincase and gear oil by AMSOIL is a made from a 100% synthetic formulation that specializes in resisting shear and chemical breakdown better than any conventional fluids. It is made with extreme pressure additives that not help improve the life of the chain and gears, but also prevent them from wearing.

AMSOIL chaincase and gear oil also repels water and prevents the chain and gear from rusting, oxidation, and even foam. Another highlight feature of this oil is that it has a low pour point that ensures low temperature starting of your snowmobile, reducing the overall effort on the vehicle to deliver maximum power.

SCL Synthetic Chaincase Lubricants

SCL chaincase lubricant is specially engineered chaincase oil by Polaris with the main focus of protecting the chains and sprockets while the snowmobile is running on a high temperature and speed. It is currently one of the best chaincase oils available in the market and works effectively on any snowmobile.

It is made of a fully synthetic formula with very high viscosity to provide excellent film strength and ensure maximum protection for the chain, gears, and sprockets. It also features a specialized low sulfur additive that resists snowmobile from breaking down at high temperatures.

Apart from this, SCL is also designed for superior anti-wear and shock protection of chain pins. It also protects chaincase seal material and is an excellent choice to prevent gears and chains from rusting and oxidation.

How to Change the Chaincase Oil in Your Snowmobile?

Changing the chaincase oil might sound all technical and difficult, but let me tell you that it is not.

It is rather a simple process that can be done by anyone. However, before you begin, make sure that you have everything you need. The things required in this process are

  • A simple bucket
  • Degreaser
  • Parts Cleaner
  • Thread-locker
  • Dipstick

Here, you will need a degreaser to loosen the old oil metal shavings sludge, while the parts cleaner is required to clean the chaincase before you lubricate the chain with new oil. The thread-locker though, is a support device that prevents the bolts from backing out and also prevents the oil from leaking. A Dipstick is lastly used to check the amount of oil-filled.

Once you have everything ready, just follow the simple steps given below to change the chaincase oil in your snowmobile.

  1. Start by placing the bucket under the chaincase drain plug and then remove the plug to drain the oil.
  2. Once the oil is drained, remove the chaincase cover to expose the interior of the chaincase containing gears and chain.
  3. After taking off the chain cover, check the gears and chain for any problems. Make sure to check the chain for wear and tear, and also make sure that it isn’t too loose.
  4. Next, spray the degreaser on the entire interior of the chaincase and even in the cover to loosen the oil and metal shavings sludge.
  5. Now you will have to clean the interior, start by spraying parts cleaner over everything inside the chaincase and cover, and then clean and rinse all the gunk out.
  6. It is considered better to start from the top and then work your way down or vice versa so that you can cover everything.
  7. Before you do anything else, your chaincase should be completely dry, therefore it is better to leave it for a while to dry out.
  8. Once the inside is completely dry, you will have to put everything back together. Place the drain plug and the chaincase cover and then fit the bolts using the thread-locker, which will keep the bolts intact and prevent the oil from leaking.
  9. After putting everything back in order, fill the chaincase with the amount of chaincase oil suggested by the manufacturer of your snowmobile.
  10. After filling the oil, use the dipstick to check if you have filled enough and then the tightly closed lid to avoid any air gaps.

Final Words

Chaincase oil is an essential part of your snowmobile. It ensures a smooth and comfortable running of your snowmobile and can even protect the gears and chains at high temperatures and speed. It is highly suggested that you change your chaincase oil seasonally as the oil can get contaminated by water and metal slivers from chain and sprockets.

If you want to ensure a smooth ride even at high speed and temperature, then the right chaincase oil choice is necessary. You can pick any one of the two above mentioned chaincase oil brands for complete protection of your gear, chains, and sprockets, and high performance of your snowmobile.
