As winter approaches and snow begins to blanket the ground, a reliable snowblower becomes an indispensable tool for many homeowners and businesses. Ensuring that your snowblower operates efficiently throughout the season requires proper maintenance, and one of the most critical aspects of this is selecting the right oil. This guide will delve into the various types of oil suitable for snowblowers, explaining their characteristics, benefits, and how to make an informed choice to keep your machine running smoothly.
Understanding Snowblower Engine Types
Snowblowers are typically equipped with either two-stroke or four-stroke engines, and the type of oil required varies accordingly.
Two-Stroke Engines: These engines are less common in modern snowblowers but are still found in some models. They require oil to be mixed with gasoline, as they do not have a separate oil reservoir. The oil used in two-stroke engines must be specifically designed for this purpose, as it needs to provide lubrication, reduce deposits, and burn cleanly to minimize exhaust smoke and emissions.
Four-Stroke Engines: More common in current snowblower models, four-stroke engines have a separate oil reservoir and use straight gasoline. These engines are similar to those found in lawnmowers and cars. The oil used in four-stroke engines is responsible for lubricating the engine components, reducing friction, and preventing wear and tear.
Types of Oil for Snowblowers
Conventional Oil: Also known as mineral oil, conventional oil is derived from refined crude oil. It is less expensive and suitable for four-stroke engines, especially in older models. However, conventional oil tends to break down more quickly than synthetic alternatives, especially in extreme cold, which can lead to increased wear and tear on the engine.
Synthetic Oil: Made from chemically modified petroleum components or other raw materials, synthetic oil is designed to provide superior performance in extreme temperatures. It offers better lubrication, reduced friction, and a longer lifespan compared to conventional oil. For snowblowers, synthetic oil is particularly beneficial as it remains fluid in extremely low temperatures, ensuring consistent engine performance.
Synthetic Blend Oil: This oil is a mix of conventional and synthetic oils, offering a balance between cost and performance. Synthetic blend oils provide better protection than conventional oils but at a lower price point than full synthetics. They are a good option for those seeking improved performance without the higher cost of fully synthetic oil.
Two-Stroke Oil: Specifically designed for two-stroke engines, this oil is mixed with gasoline in a specific ratio, usually 50:1 or 40:1, depending on the manufacturer’s specifications. Two-stroke oil needs to be high-quality to ensure it burns cleanly and provides adequate lubrication to prevent engine damage.
Factors to Consider When Choosing Oil
Manufacturer Recommendations: Always refer to the snowblower’s owner’s manual for the manufacturer’s oil recommendations. Using the specified oil type and viscosity ensures optimal performance and avoids voiding the warranty.
Viscosity: Viscosity refers to the oil’s resistance to flow and is indicated by the numbers on the oil container (e.g., 5W-30). For snowblowers, oils with lower viscosity ratings are generally preferred because they remain fluid in cold temperatures, ensuring proper lubrication during startup and operation.
Temperature Range: The climate in which you operate your snowblower significantly influences the choice of oil. For instance, 5W-30 oil is suitable for most winter conditions, while 0W-30 oil may be better for extremely cold environments due to its lower viscosity at low temperatures.
Engine Type: As mentioned, the type of engine (two-stroke or four-stroke) dictates whether you need oil that mixes with fuel or is used separately. Using the wrong type of oil can lead to engine damage.
Synthetic vs. Conventional: While synthetic oils generally offer superior performance, they are also more expensive. Assess your budget and the frequency of snowblower use to determine whether the benefits of synthetic oil justify the additional cost.
Popular Oil Brands and Products
Several reputable brands offer high-quality oils suitable for snowblowers. Some of the top choices include:

Craftsman 4-Cycle Engine Oil 5W-30: A reliable conventional oil that offers good protection for four-stroke engines in moderate winter conditions.
How to Change Snowblower Oil
Regular oil changes are crucial for maintaining the performance and longevity of your snowblower. Here’s a step-by-step guide:
Warm Up the Engine: Run the snowblower for a few minutes to warm up the oil, making it easier to drain.
Disconnect the Spark Plug: For safety, disconnect the spark plug wire to prevent accidental startup.
Drain the Oil: Position an oil pan under the drain plug, remove the plug, and let the oil drain completely. Be sure to properly dispose of the used oil according to local regulations.
Replace the Oil Filter: If your snowblower has an oil filter, replace it according to the manufacturer’s instructions.
Add New Oil: Reinsert the drain plug and fill the engine with the recommended type and amount of new oil. Use a funnel to avoid spills.
Check the Oil Level: After filling, check the oil level with the dipstick and add more if necessary.
Reconnect the Spark Plug: Once the oil change is complete, reconnect the spark plug wire.
