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.
How to Tell if a Snow Blower Needs New Oil
Even if it hasn’t been used much, engine oil can still go bad over time, and oil changes are never a bad thing.
Watch for these signs that it’s time for an oil change (change that oil filter too):
- Dark or dirty oil: Fresh oil is usually light in color. If it looks thick, black, or sludgy, it’s due for replacement.
- Low oil level: Check the dipstick before each use. If the engine oil sits below the fill line, add or replace it.
- Strange engine sounds: Knocking or grinding noises can mean the oil isn’t protecting the engine parts properly.
- Hard starting or stalling: Old or contaminated oil can make the engine sluggish, especially in cold weather.
- Burning smell or smoke: A burnt odor or light smoke can point to overheated, degraded oil.
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.
"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," notes Bollingmo. "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."
FAQ
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.
How often should I check the oil during the winter?
It’s a good idea to check the oil every few uses. Snow blowers work hard in cold conditions, and oil levels can drop faster than you might expect. A quick check before each storm helps catch low or dirty oil before it causes engine strain.
What should I do with old oil after changing it?
Never pour used oil down a drain or onto the ground. Pour it into a sealed container and take it to a local recycling center, auto shop, or hardware store that accepts used oil. Proper disposal protects the environment and keeps your workspace clean.
