How to Change the Oil in Your MTD Snow Blower

Why Regular Oil Changes Matter

Oil keeps your MTD snow blower's engine running smoothly. Over time, oil gets dirty and breaks down. When oil breaks down, it can't protect your engine as well. Dirty oil can cause your engine to wear out faster and run less efficiently. Changing your oil regularly helps your machine work better and last longer. This guide walks you through the basic steps so you understand how to do this maintenance task yourself.

Think of oil like the lifeblood of your engine. It lubricates moving parts, reduces friction, and helps keep everything cool. Without clean oil, those parts rub together and wear down. By changing your oil on a regular schedule, you're investing in the long life of your snow blower. Most owners find that regular oil changes prevent bigger problems down the road.

What You'll Need

Before you start, gather these items to make the job easier and safer:

• New oil (check your owner's manual for the right type and amount)
• An oil drain pan or container to catch the old oil
• A wrench or socket set that fits your drain plug
• A new oil filter (if your model has one)
• An oil filter wrench (if needed)
• Clean rags or paper towels
• A funnel for pouring oil
• Your owner's manual for reference

Having everything ready before you start makes the job go faster and smoother. You won't have to stop halfway through to hunt for a tool. If you're not sure what type of oil your snow blower needs, check the manual or look at the engine itself—the information is often printed there. Gathering supplies also means you'll be safer because you won't rush through the process.

Prepare Your Snow Blower

Start with a cold engine. If you've been using your snow blower recently, let it cool down first. This keeps you safe from burns and also helps the oil drain better. A warm engine can still hold some oil in the filter and engine block, so waiting a bit ensures you get more of the old oil out. Give it at least 15 to 20 minutes to cool if you've just been using it.

Place your snow blower on a flat, level surface where you have room to work. Make sure you have good lighting—a work light or flashlight helps you see what you're doing. Clear away any snow or debris from around the engine. You'll need space to get underneath or to the side to reach the drain plug. Working in a garage or covered area is ideal, but any sheltered spot works. Never work under your snow blower if it's not securely supported.

Drain the Old Oil

Locate the oil drain plug on the bottom of your engine. It's usually a bolt or plug sticking out from the lowest part of the engine. Position your drain pan underneath it to catch the oil. Using your wrench, loosen the drain plug by turning it counterclockwise. Once it's loose enough, carefully unscrew it by hand and let the old oil drain completely into the pan. This may take several minutes, so be patient. The oil will flow faster at first and then slow to a drip.

Once the oil stops dripping, wipe the drain plug clean with a rag. Check the rubber washer or gasket on the plug—if it looks cracked or damaged, you may want to replace it. A damaged washer can cause leaks. Once the plug is clean and dry, set it aside in a safe place where you won't lose it. You'll need it again in a few minutes.

Replace the Oil Filter (If Your Model Has One)

Some MTD snow blowers have an oil filter, while others don't. Check your owner's manual to see if yours does. If it does, locate it on the engine—it's usually a cylindrical canister. Use an oil filter wrench to turn it counterclockwise until it comes free. Carefully remove it and let any remaining oil drain into your pan. Be careful because a little oil may still be inside the filter.

Before installing the new filter, rub a thin layer of new oil around the rubber gasket, which is the ring on top of the filter. This helps create a good seal and makes it easier to remove next time. Screw the new filter on by hand until the gasket touches the engine, then turn it another three-quarter turn. Don't over-tighten it—hand-tight is all you need. Over-tightening can damage the filter and make it hard to remove later.

Install the Drain Plug

Screw the drain plug back in by hand first. Make sure it goes in straight so you don't cross-thread it. Once it's hand-tight, use your wrench to tighten it snugly. Don't over-tighten—this can strip the threads and cause leaks. You want it tight enough that it won't leak, but not so tight that you crack the engine block.

If your drain plug has a rubber washer, make sure it's in place before you reinstall the plug. A missing or damaged washer is a common cause of oil leaks. Take a moment to double-check that everything looks right before you move on to adding new oil.

Add New Oil

Place a funnel in the oil fill opening on top of the engine. Slowly pour in the new oil. Check your owner's manual for the correct amount. Most small engines in MTD snow blowers need between one and two quarts. Pouring slowly prevents spills and helps you control the amount. If you pour too fast, oil can splash out and make a mess.

After adding oil, wait a minute for it to settle and flow down into the engine. Then check the level using the dipstick or sight glass, depending on your model. The dipstick is usually a rod that you pull out to check the level. Wipe it clean, reinsert it, and pull it out again to see where the oil level is. Add a bit more if needed to reach the full line. Don't overfill—too much oil can damage your engine just like too little can.

Run Your Engine

Start your snow blower and let it run for a minute or two. This circulates the new oil through the engine and helps it reach all the moving parts. You'll also get a chance to check for any leaks. Stop the engine and wait a few minutes for the oil to settle, then check the oil level again. Top it off if necessary. This second check is important because some oil gets absorbed into the filter when you first run the engine.

If you notice any oil leaking from the drain plug or filter, stop and tighten them a bit more. A small drip is normal right after an oil change, but steady leaking means something isn't tight enough. Once everything looks good, your oil change is complete.

Dispose of Old Oil Properly

Never pour old oil down a drain or into the ground. Used oil harms the environment and can contaminate water supplies. Take your old oil to a local recycling center, auto parts store, or service station that accepts used oil. Many places take it for free. Some communities have special collection days for hazardous waste, including used oil. Call your local waste management office to find out what options are available near you.

Store your old oil in a sealed container until you can drop it off. Label it clearly so no one mistakes it for something else. Keeping used oil in a safe place also prevents spills in your garage or shed.

Keep Track of Your Maintenance

Write down the date and the hours on your engine when you change the oil. You can often find the hour meter on the engine itself, or you can estimate based on how much you've used it. This helps you remember when the next change is due. Most MTD snow blower engines need an oil change every 50 hours of use or once a season, whichever comes first. Some newer models may have longer intervals, so check your manual.

Keeping a maintenance log is a simple way to stay on top of this task. You can write it in a notebook, on a calendar, or even in your phone. Regular oil changes are one of the easiest ways to keep your snow blower running well year after year. By staying on schedule, you'll avoid many common engine problems and get more seasons of use from your machine.

Frequently Asked Questions

How often should I change the oil in my MTD snow blower?

Most MTD snow blower engines need an oil change every 50 hours of use or once a season, whichever comes first. If you use your snow blower heavily during winter, you may need to change the oil more often. Check your owner's manual for the specific recommendation for your model. Keeping track of your hours helps you stay on schedule.

What type of oil should I use in my MTD snow blower?

The correct oil type depends on your specific model and where you live. Check your owner's manual for the exact recommendation. Most small engines use SAE 30 oil in warmer climates or SAE 10W-30 in colder areas. Using the wrong oil can affect how your engine runs and may cause damage. When in doubt, refer to your manual or contact an MTD dealer.

Can I change the oil if the engine is still warm?

It's best to wait until the engine is completely cool before changing the oil. A warm or hot engine can burn you, and warm oil flows faster, making it harder to control. Letting the engine cool also allows some of the oil in the filter to drain back into the pan, so you get more of the old oil out. Wait at least 15 to 20 minutes after using your snow blower before starting an oil change.

What should I do if I spill oil while changing it?

Clean up spills right away to prevent slipping hazards and environmental damage. Use rags or paper towels to soak up the oil, then dispose of them properly. If the spill is large, sprinkle cat litter or sand on it to absorb the oil, then sweep it up. Never use water to clean up oil—it spreads the oil around and makes it worse. Dispose of all contaminated materials according to your local waste guidelines.
