While it might seem tempting to skip the maintenance steps for a tool that spent more time in storage than in service, the truth is that even a snow blower sitting idle still needs attention.
Skipping simple tasks like oil changes could lead to engine issues when you need it most. So before the snow flies, let’s dive into the importance of oil maintenance and what you should consider to keep your snow blower in top condition this winter.
Should you replace the oil on your snow blower every year?
"Snow blowers are often parked in the garage and pushed into the first snowfall with the expectations of top-notch performance," shares Wes Bollingmo, Channel & Product Support Manager at Toro. "Changing the oil in a gas-powered snow blower is just one of the keys to ensuring that the machine meets those expectations."
He adds, "Oil in a small engine doesn't break down very fast but it does become contaminated. Moisture from the air and exhaust will build up in the oil within a very short time. This contamination will result in increased wear and eat away at internal parts over time."
Following the recommended oil change schedule for the machine can help prevent expensive repairs.
Signs Your Snow Blower Needs More Than Just an Oil Change
Regular oil changes are important, but they aren't the only maintenance required for most snow blowers. If your machine starts to run roughly, doesn’t engage properly, or has trouble throwing snow, these may be signs of a bigger issue like a worn belt, dull auger blades, or clogged carburetor. Watch for fuel issues, and pat attention to the fuel lines, gas tank, and other signs of wear associated with a gas-powered snow blower.
Also listen for strange sounds, such as grinding or squealing — those can indicate internal problems that require additional maintenance. Taking the time to correct issues based on these warning signs can prevent small issues from becoming costly repairs down the road.
What type of oil and fuel is best for a snow blower in winter conditions?
It's important to use a winter-grade oil that can withstand freezing temperatures. A synthetic 5W-30 oil is commonly recommended, as it offers protection in low temperatures and helps the engine start easily. Bollingmo adds, "We recommend using engineered fuel like Toro’s All-Season 4-Cycle Fuel, which is designed to help the engine start more easily and idle smoothly. Plus, with a shelf-life of 2 years once opened and 5 years unopened, it’s a great choice for powering snow blowers that are used intermittently. Using a premium fuel like this can also lead to a cleaner fuel system, better fuel economy and less wear and tear on engine parts."
Can I use the same oil in my snow blower that I use for my lawn mower?
No, the oil used in lawn mowers during summer months may not perform well in cold weather. Snow blowers require oil that remains fluid in freezing temperatures, like winter-grade synthetic oil. Always check the manufacturer's recommendation.
