Selecting the Right Oil for Ariens Snowblower: A Full Guide

by Anna

Ariens snowblowers are known for their exceptional performance and reliability when it comes to clearing snow during the winter months. However, like any machine with an internal combustion engine, they require regular maintenance, including changing the oil. Selecting the appropriate type of oil for your Ariens snowblower is crucial to ensure it runs smoothly and efficiently throughout the season. In this comprehensive guide, we will delve into the various factors to consider when choosing oil for your snowblower, as well as provide recommendations for the best oils on the market.


Importance of Choosing the Right Oil

Choosing the right oil for your Ariens snowblower is essential for several reasons. First and foremost, it directly impacts the engine’s performance and longevity. The engine relies on oil for lubrication, which minimizes friction, reduces wear and tear, and ensures the engine components work together seamlessly. Using the wrong oil can result in poor lubrication, increased engine wear, and ultimately, engine failure.


Furthermore, the type of oil you choose can affect how your snowblower operates in cold weather conditions. Winter weather places additional stress on the engine, and using the correct oil helps maintain engine efficiency even in sub-freezing temperatures. Inadequate lubrication in cold weather can lead to engine damage or failure, making it crucial to select oil with the right cold-weather properties.

Factors to Consider When Choosing Oil

Several factors must be considered when selecting the right oil for your Ariens snowblower:

Oil Viscosity: Viscosity refers to the thickness or flowability of the oil. It is typically denoted by a numerical rating, with two numbers separated by a “W” (e.g., 5W-30). The first number represents the oil’s viscosity in cold temperatures, and the second number represents its viscosity at operating temperatures. For Ariens snowblowers, it is recommended to use a multi-viscosity oil, such as 5W-30, as it provides the ideal balance between cold-weather startup and hot-weather operation.

Cold-Weather Performance: The ability of the oil to flow and provide lubrication in freezing temperatures is crucial for a snowblower. Ariens snowblowers are often used in cold climates, and using oil with good cold-weather properties is vital to ensure your snowblower starts reliably and operates smoothly. Look for oils labeled as “all-season” or “for cold weather.”

API Classification: The American Petroleum Institute (API) classifies motor oils based on their performance characteristics. When choosing oil for your snowblower, look for oils with the “SJ” or “SL” classification. These designations indicate that the oil meets the latest industry standards for engine protection.

Synthetic vs. Conventional: You can choose between synthetic and conventional oils. Synthetic oils tend to offer better performance in extreme temperatures and provide superior engine protection. They also have a longer lifespan, making them a popular choice for those who want to extend the time between oil changes. However, synthetic oils are typically more expensive than conventional oils.

Brand and Quality: The brand and quality of oil also matter. Reputable brands often have a history of producing high-quality oils that are formulated to meet the needs of specific engines and applications. Using a trusted brand’s oil can help ensure the reliability of your snowblower.

Recommended Oils for Ariens Snowblowers

After considering the factors mentioned above, here are some recommended oils for your Ariens snowblower:

Ariens 5W-30 Synthetic Engine Oil: Designed specifically for Ariens snowblowers, this synthetic oil offers excellent cold-weather performance and engine protection. It is formulated to meet the requirements of Ariens engines, ensuring optimal performance.

Briggs & Stratton Synthetic Small Engine Oil: This synthetic oil is suitable for a wide range of small engines, including those in Ariens snowblowers. It offers enhanced cold-weather starting, reduced oil consumption, and superior protection against wear.

Mobil 1 5W-30 Synthetic Motor Oil: Mobil 1 is a well-known brand that offers high-quality synthetic motor oils. The 5W-30 formula is suitable for cold-weather applications, and it provides excellent protection and lubrication for your snowblower’s engine.

Castrol GTX 5W-30 Conventional Motor Oil: If you prefer conventional oil, Castrol GTX 5W-30 is a solid choice. It provides good protection in cold weather and is available at an affordable price point.

Oil Change Procedure

Once you’ve selected the appropriate oil for your Ariens snowblower, it’s essential to follow the manufacturer’s guidelines for changing the oil. Here is a general procedure for changing the oil in your snowblower:

Warm Up the Engine: Start your snowblower and allow it to run for a few minutes. This warms the oil and makes it easier to drain.

Turn Off the Engine: Ensure the snowblower is turned off, and the engine is cool to the touch.

Locate the Oil Drain Plug: Typically, the oil drain plug is located on the bottom of the engine, near the blade or auger area. Consult your owner’s manual for the exact location.

Position a Drain Pan: Place an oil drain pan beneath the oil drain plug to catch the used oil.

Remove the Drain Plug: Carefully remove the drain plug and allow the old oil to drain into the pan.

Replace the Drain Plug: Once all the old oil has drained, replace the drain plug and tighten it securely.

Add New Oil: Remove the oil filler cap, usually located on the top of the engine, and add the recommended oil. Be sure to pour it slowly and check the oil level using the dipstick.

Check the Oil Level: Start the engine and let it run for a minute or two. Then, shut it off and check the oil level using the dipstick. Add more oil if needed to bring it to the appropriate level.

Dispose of Used Oil Properly: Used oil is considered hazardous waste and should be disposed of according to local regulations. Many auto parts stores and recycling centers accept used oil for proper disposal.


Selecting the right oil for your Ariens snowblower is crucial for maintaining its performance and ensuring its longevity. By considering factors such as oil viscosity, cold-weather performance, API classification, and the choice between synthetic and conventional oils, you can make an informed decision. Additionally, choosing a high-quality oil from a reputable brand will contribute to the reliability of your snowblower. Proper maintenance, including regular oil changes, will help your Ariens snowblower continue to clear snow effectively for many winters to come.
