What to Consider When Choosing the Best Oil for Snow Blower Maintenance

The right maintenance engine oil can make the difference between a snow blower that starts right up and one that’s sidelined with a gummed-up engine. Ahead, learn how viscosity, oil type, and other factors affect engine oil performance in a snow blower.

Type

Gas-powered snow blowers use 4-cycle engine oil, which is oil for engines that use separate tanks for gas and oil, much like a car engine. The gas fuels the engine, while the oil lubricates it, each from its own tank. Smaller engines, such as those on a chainsaw, have a 2-cycle engine. This type of small engine uses an oil and gas mixture that goes into one tank.

Identifying the right type of engine oil is easy. The oil container has “4-cycle” or “2-cycle” clearly printed on the label. Although some 4-cycle engine oils are labeled for “small engines,” it’s actually the same oil commonly used in cars and trucks.

Don’t use 2-cycle engine oil in a snow blower, as it will not properly lubricate the engine and will damage it. The motors on electric snow blowers don’t require engine oil.

Viscosity

Viscosity refers to the thickness of the oil. Higher viscosity oil is better at protecting and lubricating the engine when operating at high temperatures and at peak load (high RPMs). Oil with a low viscosity remains thinner at lower temperatures, promoting better flow through the engine, making it easier to start and more efficient to run.

Viscosity is based on a scale created by SAE International, formerly known as the Society of Automotive Engineers (SAE). Motor oil has two viscosity ratings:

  • The first rating—the “W” (for “winter”) after the number—represents the cold temperature viscosity. For example, an oil rated 5W flows better at lower temperatures than a 10W oil.
  • The second number indicates the high-temperature viscosity; for example, an oil with a high-temperature viscosity of 30 stays thicker at higher temperatures.

Since snow blowers operate exclusively in cold weather, they typically use SAE 5W-30 weight oil, which ensures the engine will start in cold weather. Make sure to check the maintenance section of the snow blower’s operating manual for the proper oil weight.

Synthetic vs. Standard

Not all 5W-30 engine oils are the same. Some engine oils are synthetic, which means they use higher quality base oils than conventional oils. Synthetic oils can generally withstand higher temperatures and resist breakdown better. This means synthetic oil lasts at least 50 percent longer than conventional oil, so the snow blower probably will require less-frequent maintenance.

Many synthetic oils also contain additives to help improve engine performance. Additives include detergents that flush grime and buildup from the engine parts, which helps extend engine life, and chemicals that enhance lubrication. Other additives leave a coating on the engine parts. Synthetic oils are generally more expensive, often costing several times more than conventional oils.

Versatility

The 4-cycle engine oil that snow blowers use is the same oil used in any 4-cycle engine, which means it also can be used in lawn mowers, power washers, and even cars and trucks. The 5W-30 oil provides adequate protection not only during the colder months but also in warmer months, thanks to a high-temperature viscosity rating.

Engine oil generally comes in 1-quart bottles, ideal for snow blowers that hold around that much. Motor oil also comes in 5-quart containers.

With a shelf life of about five years, 5W-30 oil can be stored in the garage so it’s on hand when needed. Keep motor oil in a cool, dry environment in a tightly sealed container to prevent contamination.

FAQs

Now that you know more about oil for snow blowers, you may have additional questions. To learn about the best type of oil for your snow blower, keep reading for answers to some of the most commonly asked questions about snow blower engine oil.

Q. Can I use synthetic oil in my snow blower?

Yes, synthetic oil can be used, and it may be the best oil for a snow blower. Synthetic oils are refined to run cleaner, leaving fewer deposits in the engine. Many also include additives that clean grime and sludge from the engine to improve performance.

Q. Can I use car oil in my snow blower?

Yes. Snow blowers, like cars, are 4-cycle engines, so they use the same type of motor oil. Make sure to use a motor oil weight with a low-temperature viscosity rating, such as 5W-30.

Q. How do I know which oil is the right one for my snow blower?

Snow blowers operate in frigid temperatures, so the most important factor to consider is viscosity. Use motor oil with a low-temperature viscosity rating, such as 5W-30 or 5W-20, to ensure the snow blower starts easily and runs smoothly.

Q. What happens if I put too much oil in my snow blower?

Adding too much oil to a snow blower, or any 4-cycle engine, will cause the oil to rise and come in contact with other moving parts around the engine, aerating the oil and creating a huge mess.
