How to Change the Oil in Your Briggs & Stratton Snow Blower

Why Regular Oil Changes Matter

Oil keeps your snow blower's engine running smoothly. Over time, oil gets dirty and breaks down, losing its ability to protect engine parts. Changing it regularly helps your engine last longer and work better when you need it most—especially before winter arrives. Fresh oil reduces wear on moving parts, helps the engine run cooler, and prevents buildup that can damage your machine.

Many snow blower owners skip oil changes and then wonder why their equipment won't start in the fall or runs poorly during the season. A simple oil change takes less than an hour and costs very little compared to engine repairs. Making this part of your yearly maintenance routine is one of the best things you can do for your snow blower's performance and lifespan.

What You'll Need

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

• New oil (check your owner's manual for the right type and amount)
• An oil drain pan or container to catch old oil
• A wrench or socket set that fits your drain plug
• An oil filter wrench (if your model has a removable filter)
• A rag or paper towels for cleanup
• A funnel to pour oil safely
• Jack stands or blocks (optional, for extra safety and stability)
• Newspaper or cardboard to protect your work surface

Having everything ready before you begin means you won't need to stop midway through to hunt for a tool. Lay out your supplies on a clean work surface so you can reach them easily. If you're working in a garage or on a driveway, put down newspaper or cardboard to catch any spills and make cleanup simpler.

Step 1: Prepare Your Snow Blower

Start by letting the engine cool completely. Never work on a hot engine—the oil and metal parts can burn your skin badly. If you've been using the snow blower, wait at least 30 minutes before starting work. You can check if it's cool enough by carefully touching the engine housing (not the muffler) with your hand.

Once it's cool, move the snow blower to a flat, level surface where you can work comfortably. Make sure the ground is solid and won't tip or shift. If you want extra stability, use jack stands or blocks to support the machine safely. Never rely only on a jack to hold the snow blower while you work underneath it.

Step 2: Locate the Drain Plug

Find the oil drain plug on the bottom or side of the engine. Your owner's manual shows exactly where it is on your specific model. The drain plug is usually a bolt or screw that sticks out from the engine block. It may be hard to spot if oil has dried on it, so look carefully and feel around if needed.

Once you find it, position your drain pan directly underneath to catch the old oil. Make sure the pan is large enough—old oil can take up more space than you'd expect. If you're working on a driveway, place newspaper around the pan to catch any drips that might splash out.

Step 3: Drain the Old Oil

Use your wrench to loosen the drain plug by turning it counterclockwise. Start slowly so you don't strip the threads. Once it's loose enough to turn by hand, carefully unscrew it the rest of the way. Be ready—oil may still be warm and could drip on you. Let all the old oil drain into the pan. This may take several minutes, so be patient and don't rush.

While you wait for the oil to drain completely, wipe the drain plug clean with a rag. Remove any dirt, old oil, or debris from the plug and the area around it. A clean plug and hole make it easier to install the new plug correctly and help prevent leaks. Once the oil stops dripping, you can move on to the next step.

Step 4: Replace the Drain Plug

Screw the drain plug back in by hand first. This prevents you from accidentally cross-threading it, which can damage the hole and cause oil leaks. Once it's started by hand and sitting flush in the hole, use your wrench to tighten it. Turn the wrench slowly and steadily until the plug feels snug.

Don't over-tighten the drain plug—this is a common mistake that can crack the engine block or strip the threads. You want it tight enough that it won't leak, but not so tight that you're using all your strength. A good rule is to tighten it until you feel resistance, then turn it just a quarter turn more.

Step 5: Replace the Oil Filter (If Applicable)

Some Briggs & Stratton models have an oil filter, while others don't. Check your owner's manual to see if your snow blower has one. If it does, you'll usually find it on the side or top of the engine. The filter looks like a metal cylinder and may have oil residue on it.

Use an oil filter wrench to loosen the filter by turning it counterclockwise. Once it's loose, carefully unscrew it by hand and let any remaining oil drain into your pan. Before installing the new filter, rub a thin layer of new oil around the rubber gasket (the ring) on top of the filter. This helps create a good seal. Screw the new filter on by hand until the gasket touches the engine, then turn it about three-quarters of a turn more. Don't use the wrench to tighten the filter—hand-tight is correct.

Step 6: Add New Oil

Place your funnel in the oil fill opening on top of the engine. The opening usually has a cap labeled "Oil" that you'll need to remove first. Slowly and carefully pour in the new oil. Don't rush this step—if you pour too fast, oil can splash out or overflow.

Check your owner's manual for the exact amount of oil your snow blower needs. Different models require different amounts, and using too much or too little can cause problems. After pouring the oil, replace the oil cap and make sure it's tight. Wipe up any spills with a rag.

Step 7: Check Your Work

Wait about one minute after adding new oil. This gives the oil time to settle and flow down to the bottom of the engine. Then locate the dipstick, which is usually a thin rod with markings on it. Pull it out completely and wipe it clean with a rag or paper towel.

Put the dipstick back in all the way, then pull it out again to check the oil level. The oil should reach the "full" mark on the stick. If it's below the mark, add a little more oil and check again. If it's above the mark, you've added too much—carefully remove the excess with a turkey baster or syringe. Getting the level right is important for proper engine operation.

Step 8: Dispose of Old Oil Properly

Never pour old oil down the drain, into the ground, or into a storm drain. Used oil is toxic and harms the environment. Instead, take your drain pan of old oil to a local recycling center, auto parts store, or service station. Many of these places accept used oil for free, and some may even take the oil filter too.

Call ahead if you're not sure whether a place accepts used oil. Most communities have at least one location that will take it. Proper disposal is not only good for the environment—it's the law in most areas. Taking a few minutes to dispose of oil correctly is part of being a responsible equipment owner.

When to Change Your Oil

Check your owner's manual for the recommended oil change schedule for your specific model. Most Briggs & Stratton snow blowers need an oil change every 50 hours of use. If you use your snow blower regularly during winter, this might mean changing the oil once or twice per season.

At a minimum, change your oil at least once a year before winter storage. Even if you haven't used the snow blower much, old oil can break down and lose its protective qualities. Mark your calendar in the fall as a reminder to change the oil before you need the snow blower. Starting the season with fresh oil helps ensure your machine will run reliably when the snow arrives.

Frequently Asked Questions

What type of oil should I use in my Briggs & Stratton snow blower?

The correct oil type depends on your specific model and where you live. Your owner's manual will list the recommended oil grade, such as SAE 30 or 10W-30. In general, Briggs & Stratton recommends SAE 30 oil for temperatures above 40°F and 10W-30 for colder weather. Using the wrong oil can affect engine performance and may void your warranty. Always check your manual before buying oil.

How often should I check the oil level between changes?

It's a good idea to check your oil level before each use, especially at the start of the snow season. A quick dipstick check takes only a minute and helps you catch low oil before it causes engine damage. If you notice the level dropping quickly between changes, your engine may have a leak or be burning oil, which means you should have it inspected by a service technician.

Can I change the oil without draining it completely?

No, you should always drain the old oil as completely as possible. Mixing old, dirty oil with new oil reduces the effectiveness of the new oil and defeats the purpose of an oil change. The old oil contains dirt, metal particles, and other contaminants that can damage your engine. Draining completely ensures you're starting fresh with clean oil that will protect your engine properly.

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

If you spill oil on the ground, cover it with sand, dirt, or oil absorbent material to prevent it from spreading. Let it soak in, then sweep it up and dispose of it as you would used oil. Never hose down an oil spill with water, as this spreads the oil and makes cleanup harder. If you spill oil on your driveway, use a degreaser or oil-specific cleaner to remove the stain once you've cleaned up the bulk of the spill.

Final Thoughts

Changing your own oil saves money and keeps you familiar with your equipment. Regular oil changes are one of the simplest and most effective ways to keep your snow blower running smoothly for years to come. The small amount of time and effort you invest in this maintenance task pays off in reliable performance when you need your equipment most.

If you run into any problems during the process or your manual shows something different from these steps, always follow your specific owner's manual for your model. Every snow blower is slightly different, and your manual contains the most accurate information for your machine. Taking care of your equipment now means fewer headaches and better performance in the seasons ahead.
