Is your MTD snowblower ready to tackle the next winter storm? A well-maintained engine is the heart of any reliable snow-clearing machine, and one of the most crucial maintenance tasks you can perform is a regular oil change. Neglecting this simple yet vital procedure can lead to premature engine wear, decreased performance, and ultimately, a costly breakdown when you need your snowblower the most.
This article will guide you through the entire process of changing the oil in your MTD snowblower, from gathering the necessary tools and supplies to safely disposing of old oil. By following these steps, you'll ensure your snowblower operates at peak efficiency, extending its lifespan and providing you with dependable service for years to come. We'll cover everything you need to know to confidently perform this essential maintenance task.
Understanding the Importance of Regular Oil Changes
Engine oil in your MTD snowblower serves several critical functions. It lubricates moving parts, reducing friction and wear between components like the crankshaft, pistons, and connecting rods. Without adequate lubrication, these parts would grind against each other, generating excessive heat and leading to rapid deterioration.
Beyond lubrication, engine oil also plays a vital role in cooling the engine. As the oil circulates, it absorbs heat generated by combustion and friction, carrying it away from critical engine components and dissipating it. Furthermore, oil acts as a cleaning agent, suspending dirt, debris, and combustion byproducts, preventing them from accumulating and causing blockages or damage.
Over time, engine oil degrades. It loses its viscosity, its ability to lubricate effectively diminishes, and it becomes contaminated with metal shavings, soot, and unburned fuel. This degraded oil can no longer perform its essential functions, leading to increased engine stress, reduced power output, and a higher risk of internal damage. Regular oil changes replace this old, contaminated oil with fresh, high-quality lubricant, ensuring optimal engine health.
Gathering Your Tools and Supplies
Before you begin, ensure you have all the necessary tools and supplies readily available. This will make the oil change process smoother and more efficient. You will need a wrench or socket set to remove the oil drain plug, typically a 1/2-inch or 9/16-inch size, depending on your specific MTD model. A container for draining the old oil is essential; a dedicated oil drain pan with a capacity of at least one gallon is recommended.
You'll also require a funnel to pour the new oil into the engine, a clean rag or shop towels for wiping up spills, and a pair of gloves to keep your hands clean. For most MTD snowblowers, the recommended oil type is SAE 30 weight oil for temperatures above 0 degrees Fahrenheit, or SAE 5W-30 synthetic oil for colder conditions. Always consult your MTD snowblower's owner's manual for the precise oil type and capacity, as this can vary between models.
Finally, you'll need the new engine oil itself. It's best to purchase a high-quality oil specifically designed for air-cooled engines, often labeled as "lawn mower oil" or "small engine oil." Ensure you have enough oil to fill the engine to the recommended level, usually around 16 to 20 ounces, but again, confirm with your manual.
Step-by-Step Oil Change Procedure
Begin by running your MTD snowblower for a few minutes. This warms the oil, making it flow more easily and allowing it to carry more contaminants out of the engine. Once warmed, turn off the engine and ensure the snowblower is on a level surface. Locate the oil drain plug, which is typically found at the bottom of the engine block. Position your oil drain pan directly beneath the plug.
Using your wrench or socket, carefully loosen and remove the drain plug. Be prepared for the warm oil to flow out immediately. Allow the oil to drain completely into the pan, which may take several minutes. While the oil is draining, inspect the drain plug for any signs of damage or excessive metal shavings, which could indicate internal engine problems. Once the oil has finished draining, clean the drain plug and the area around the drain hole with a rag.
Reinstall the drain plug, tightening it securely but not overtightening it, as this can strip the threads. Now, locate the oil fill cap, usually marked with an oil can symbol. Remove the cap and insert your funnel. Slowly pour the new oil into the engine, referring to your owner's manual for the exact amount. Once filled, replace the oil fill cap and start the engine for a minute to circulate the new oil. Shut off the engine, wait a few minutes for the oil to settle, and then check the oil level using the dipstick. Add more oil if necessary to reach the full mark.
Troubleshooting Common Issues and Best Practices
One common issue encountered is a stubborn drain plug. If it's difficult to loosen, ensure you are using the correct size wrench and that it's firmly seated. A gentle tap with a rubber mallet on the wrench handle can sometimes help break it free. Avoid using excessive force, which could damage the plug or the oil pan. If the plug is stripped, you may need to seek professional assistance or consider replacing the oil pan.
Another potential problem is overfilling or underfilling the engine with oil. Always double-check the oil level with the dipstick after adding oil. If you overfill, carefully drain out the excess oil. If you underfill, add oil gradually until the correct level is reached. It's also important to ensure the oil fill cap and drain plug are properly sealed to prevent leaks.
A best practice is to perform oil changes at the recommended intervals specified in your MTD snowblower's owner's manual, typically after every 25-50 hours of operation or at the beginning of each snow season. Keeping a maintenance log can help you track when your last oil change was performed. Always dispose of used oil responsibly by taking it to a local recycling center or auto parts store that accepts used motor oil.
Disposing of Used Oil Responsibly
Proper disposal of used engine oil is crucial for environmental protection. Never pour used oil down drains, into sewers, or onto the ground, as it is a hazardous waste and can contaminate soil and water sources, causing significant ecological damage. Most communities have designated collection sites for hazardous waste, including used motor oil.
Local auto parts stores, service stations, and municipal recycling centers are common places that accept used oil. Many of these facilities have specialized containers for collecting and recycling used oil, which can then be re-refined or used as fuel in industrial furnaces. Always store your used oil in a clean, sealed container, such as the original oil bottle or a dedicated oil disposal jug, to prevent spills during transport.
Before heading to a collection site, it's a good idea to call ahead and confirm their hours of operation and any specific requirements they may have for accepting used oil. Some facilities may have limits on the amount of oil they can accept at one time. By taking these simple steps, you contribute to a cleaner environment and ensure that hazardous waste is handled in a safe and responsible manner.

Frequently Asked Questions
How often should I change the oil in my MTD snowblower?
Consult your MTD snowblower's owner's manual for the exact recommended interval. Generally, it's advised to change the oil after every 25-50 hours of operation or at the beginning of each snow season.
What type of oil should I use for my MTD snowblower?
For most MTD snowblowers, SAE 30 weight oil is recommended for temperatures above 0 degrees Fahrenheit. For colder conditions, SAE 5W-30 synthetic oil is often preferred. Always verify the specific recommendation in your owner's manual.
Can I use car oil in my snowblower?
While some car oils might have similar viscosity ratings, it's best to use oil specifically formulated for air-cooled engines, often labeled as "lawn mower oil" or "small engine oil." These oils are designed to withstand the higher operating temperatures and specific demands of snowblower engines.
What should I do if I overtighten the oil drain plug?
If you overtighten the oil drain plug and strip the threads, it can lead to oil leaks. In minor cases, you might be able to use a slightly larger drain plug or a thread repair kit. However, for significant damage, the oil pan may need to be replaced, which is a more involved repair.
Is it necessary to warm up the engine before changing the oil?
Yes, warming up the engine for a few minutes before changing the oil is highly recommended. Warm oil flows more freely, allowing it to carry more contaminants out of the engine and ensuring a more complete drain.
