Yes, you can do it in under 30 minutes – learning how to change oil on a Craftsman snow blower is a simple job that saves you money and keeps your machine running strong for the winter.
I’ve changed the oil on my own Craftsman blower for years. It’s not as hard as it looks. You just need a few basic tools and the right oil.
This guide will walk you through each step. I’ll show you the easy way to get it done. You won’t need to pay a shop for this simple task.
Let’s get your snow blower ready for the next big storm. A fresh oil change makes a huge difference in how well it starts and runs.
Why You Need to Change the Oil
Old oil gets dirty and thick. It doesn’t protect the engine parts like it should. This can cause big problems over time.
Your snow blower engine works hard in the cold. Clean oil keeps everything moving smoothly. It stops metal parts from grinding together.
I learned this the hard way. I skipped an oil change one season. The engine got loud and was hard to start.
Changing the oil is cheap insurance. It costs way less than fixing a broken engine. A new engine can cost more than the whole machine.
The Environmental Protection Agency says proper engine care cuts down on pollution. A well-oiled engine burns fuel cleaner.
So make oil changes part of your fall routine. Do it before the first snow hits. Your future self will thank you when the blower starts right up.
Tools and Supplies You’ll Need
You don’t need fancy tools for this job. I bet you already have most of them in your garage. Let’s make a quick list.
Get a drain pan to catch the old oil. An old baking sheet or plastic tub works fine. You’ll also need a funnel for adding new oil.
You need the right size wrench. Most Craftsman snow blowers use a 3/8-inch or 1/2-inch drain plug. Check your model to be sure.
Buy the correct oil type. Your owner’s manual says which one to use. Most use SAE 5W-30 for cold weather.
Have some rags or paper towels ready. There will be some spills. An old cardboard box to lay on keeps you clean.
That’s really all you need. The whole kit costs less than twenty bucks. It’s a small price for keeping your blower happy.
Step-by-Step Oil Change Guide
First, run the engine for five minutes. Warm oil flows out much easier than cold oil. This makes the whole job quicker.
Turn off the engine and let it cool a bit. You don’t want to burn yourself on hot parts. Ten minutes of cooling is enough.
Place your drain pan under the engine. Find the drain plug on the bottom. It’s usually a bolt head facing down.
Use your wrench to loosen the drain plug. Turn it counter-clockwise. Do this slowly so the oil doesn’t splash everywhere.
Let all the old oil drain into the pan. This takes a few minutes. Tilt the machine slightly to get every last drop out.
Clean the drain plug with a rag. Put it back in and tighten it by hand first. Then give it a gentle turn with the wrench.
Now you’re ready to add fresh oil. This is the key part of learning how to change oil on a Craftsman snow blower correctly.
Adding the New Oil
Find the oil fill cap on top of the engine. It often says “Oil” on it. Remove this cap completely.
Place your funnel in the fill hole. This keeps spills to a minimum. I’ve made a mess without one before.
Pour in the new oil slowly. Check your manual for the right amount. Most take about 20 ounces, but it varies.
Stop pouring before it reaches the full mark. Use the dipstick to check the level as you go. It’s easy to add more if needed.
You want the oil level between the two marks on the dipstick. Don’t overfill it. Too much oil can cause problems too.
Once it’s at the right level, replace the oil fill cap. Wipe up any spills with your rag. A clean engine is easier to work on next time.
Start the engine and let it run for a minute. This circulates the new oil through all the parts. Listen for any odd sounds.
Check for leaks around the drain plug. A small drip means you need to tighten it a bit more. Do this with the engine off and cool.
Common Mistakes to Avoid
Don’t use the wrong type of oil. Your manual tells you which weight to use. Using car oil can damage small engines.
Never over-tighten the drain plug. You can strip the threads in the engine case. This is a costly repair.
Avoid spilling oil on the belts or tires. Oil makes rubber swell and break down. It can ruin your traction.
Don’t forget to check the oil level after running. New oil settles into the engine. The level might drop a little.
I made this mistake once. I thought I added enough, but I didn’t. The engine ran rough until I topped it off.
Never dump old oil on the ground or in the trash. Take it to an auto parts store for recycling. Most take it for free.
The Earth911 website helps you find recycling spots. Proper disposal keeps our water clean.
When to Change the Oil
Change oil at the start of each season. Fresh oil protects the engine during storage. It stops acid from building up inside.
Also change it after every 25 hours of use. That’s about one tough winter for most people. Heavy users might need two changes.
If the oil looks dark and dirty, change it. Don’t wait for the hours to add up. Your engine tells you when it needs fresh oil.
The Consumer Reports team says small engines need more care than cars. They work harder for their size.
Write the date on your machine with a marker. This helps you remember when you last changed it. I use a piece of tape on the handle.
Make oil changes part of your winter prep. Do it when you check your shovels and salt. Your blower will be ready when you need it.
Choosing the Right Oil
Check your owner’s manual first. It lists the exact oil type for your model. This is the best place to start.
Most Craftsman snow blowers use SAE 5W-30. The “W” stands for winter. This oil flows well in cold temperatures.
You can buy small engine oil at any hardware store. It comes in small bottles that are easy to pour. You won’t need a whole gallon.
Some oils say “for air-cooled engines” on the label. This is what you want. Car oil doesn’t handle the heat as well.
Synthetic oil costs more but lasts longer. It also works better in extreme cold. I use it in my blower and it starts easier.
Don’t mix different oil types. If you switch to synthetic, drain all the old oil first. Mixing can cause sludge to form.
Keep an extra bottle on your shelf. You’ll need it next season. Oil doesn’t go bad sitting in the bottle.
Tips for an Easier Job
Work on a flat, level surface. This helps you get all the old oil out. A slanted garage floor leaves oil in the engine.
Wear old clothes you don’t mind getting dirty. Oil stains don’t come out easily. I have a dedicated “mechanic shirt” for these jobs.
Use a flashlight to see the drain plug clearly. Engine compartments can be dark. Good light prevents mistakes.
Have a trash bag ready for oily rags. These can be a fire hazard. Don’t just toss them in your regular garbage.
Label your oil drain pan “Used Oil Only.” This stops anyone from using it for other things. Cross-contamination is bad.
Take a picture before you start. This helps you remember how things looked. You can refer to it if you get confused.
The Family Handyman website has great visual guides. Sometimes seeing it done helps more than reading.
What If Something Goes Wrong?
Stripped the drain plug threads? Don’t panic. You can buy a repair kit at an auto parts store.
The kit has a slightly larger plug and tap. You re-thread the hole to the new size. It’s not as hard as it sounds.
Spilled oil all over the engine? Use degreaser and water to clean it. Make sure the engine is completely cool first.
Can’t find the drain plug? Check your manual again. Some models drain from the dipstick tube with a special pump.
Added too much oil? Use a turkey baster to remove the extra. Squeeze it out into your drain pan. Easy fix.
If you’re really stuck, call a small engine repair shop. They can talk you through it. Most are happy to help over the phone.
Remember, everyone makes mistakes when they learn. My first oil change was a total mess. Now I can do it with my eyes closed.
