Changing snowblower engine oil can be messy, even though it’s necessary to keep the machine in good shape.
But, the question is - how often to change the snowblower oil? Any modern oil lasts about a month inside the snowblower fuel tank, so it’s best to check on the oil quality from time to time.
In today’s article, I’ll talk about when you should change the snowblower engine oil.
Detecting stale or poor-quality oil is quite tricky, and it’s usually too late when you can finally see the symptoms. To keep the snowblower working smoothly, you need to regularly check whether the machine is becoming hotter, making more noise, becoming less powerful, or less fuel-efficient.
Also, a sludge of black oil naturally indicates that the fuel has gone stale, and you must change it as soon as possible.
Engine oil degrades over time due to oxidation when it comes in contact with the air. Once the oil inside the fuel tank starts to heat up when the snowblower is running, its degradation process speeds up. The oil eventually turns viscous and creates black gooey sludge on oxidation.
By maintaining a fixed timeline for changing the engine oil, you can avoid the deposition of this contaminated sludge inside the machine. It’s best to replace the old oil before it deteriorates way beyond its original viscosity rating. You can protect the snowblower’s engine by draining out this old stale oil and replacing it with fresh oil.
While topping up the snowblower fuel tank with oil in between oil changes is a good practice to keep the engine healthy, it’s not an alternative to oil change. Moisture and engine contaminants can break down oil through oxidation, leading to sludge deposition and clogging up the carburetor.
You might not use a snowblower frequently every season, but it’s essential to replace the engine oil to prevent it from contamination. Ideally, it’s best to change the snowblower oil after 50 hours of operation or at least once every winter. You can also change the oil just before winter and use the snowblower throughout the season without a hitch.
If you have a new snowblower, you need to change the engine oil more frequently to maintain engine health. Change the oil after four weeks or 20 hours of operation for new snowblowers, whichever comes first. By changing the oil more often, you can improve the running-in process of new snowblowers.
Before you can refill the snowblower fuel tank with fresh fuel, check the oil level. If the oil level is low, your machine won’t start. Some snowblowers come with a fail-safe switch to indicate the low oil level. But for other models, you have to check the fuel tank manually before filling it with fresh fuel.
Park the snowblower on a flat and even surface and turn off the engine to let it cool down. Locate the dipstick inside your fuel tank to remove it and wipe it off thoroughly before reinserting it to check the present oil level inside the fuel tank.
If you can detect clear oil marks on the upper half of the stick, the snowblower fuel tank has adequate oil. However, marks on the lower half of the dipstick indicate a low oil level, and you must immediately refill the fuel tank to get the snowblower up and running again.
Marks on the area between the upper and lower halves of the stick show that the fuel tank has an acceptable oil level. So, by checking the oil marks on the dipstick, you can determine whether the machine needs an immediate fuel refill.
If you want to keep the snowblower running smoothly for a long time, check and change the engine oil on time. After going through my article, I hope you have a better idea of how frequently you have to change the snowblower oil to prevent it from going stale.
Fresh fuel can help the snowblower engine deliver smooth performance even during heavy-duty applications. You can also maintain good engine health by refilling the fuel tank with fresh fuel from time to time.
On that note, I’ll leave you to it. Take care, and I’ll see you next time!
