Yes, you can do it yourself in about 30 minutes – learning how to change oil on a Craftsman snowblower is a simple job that saves you money and keeps your machine running strong for the winter.
Your snowblower works hard all season. The engine oil gets dirty from metal bits and fuel byproducts. This dirty oil can’t protect the engine well anymore.
Changing the oil is a key part of upkeep. I’ve done this job many times on my own Craftsman models. It’s easier than you might think.
This guide will walk you through every step. You’ll learn the tools you need and the common mistakes to avoid. Let’s get your snowblower ready for the next big storm.
Why You Need to Change Snowblower Oil
Think of oil as your engine’s lifeblood. It keeps all the moving parts from grinding together. Fresh oil does this job well.
Old oil breaks down over time. It gets filled with tiny bits of metal from normal wear. It also gets dirty from combustion gases.
This dirty oil is thin and gritty. It can’t coat the engine parts properly. Metal rubs on metal without a good layer in between.
That friction makes heat. Too much heat can warp engine parts or even cause a seizure. A seized engine means a very costly repair.
Changing the oil is cheap insurance. A new oil filter and fresh oil cost very little. They protect your much more expensive snowblower engine.
Doing this job yourself saves you a trip to the shop. You also learn more about your machine. That knowledge helps with other simple fixes too.
Tools and Supplies You Will Need
Gather your tools before you start. This makes the job go smoothly. You won’t have to stop halfway to find something.
You need a drain pan to catch the old oil. A cheap aluminum baking pan from the dollar store works great. Make sure it’s big enough.
Get a socket wrench set. Most Craftsman snowblower drain plugs use a 3/8 or 1/2 inch socket. Have both sizes ready just in case.
You need fresh engine oil. Check your owner’s manual for the right type. Most use SAE 5W-30, but yours might be different.
Buy a new oil filter. Get the exact filter number for your model. You can find this in the manual or on the old filter itself.
Grab some rags and a funnel. You’ll make a bit of a mess. The funnel helps you pour new oil in without spilling.
Have a pair of work gloves handy. Old oil is dirty stuff. Gloves keep your hands clean and protect your skin.
Step-by-Step Guide: How to Change Oil on Craftsman Snowblower
First, run the engine for five minutes. Warm oil flows out much easier than cold, thick oil. This helps you drain more of the old stuff.
Turn the engine off and let it cool for a minute. You don’t want to burn yourself on hot parts. But you still want the oil to be warm.
Place your drain pan under the engine. Find the drain plug on the bottom of the oil pan. It’s usually a bolt head facing down.
Use your socket wrench to loosen the drain plug. Turn it counter-clockwise. Do this slowly until oil starts to drip out.
Unscrew the plug the rest of the way by hand. Let all the old oil drain into your pan. This might take a few minutes.
While it drains, move to the oil filter. It looks like a small metal can attached to the engine block. Place your drain pan under it too.
Use an oil filter wrench to loosen the old filter. Turn it counter-clockwise. Oil will drip out as you remove it, so be ready.
Wipe the filter mounting surface on the engine clean with a rag. Take your new filter and rub a little fresh oil on its rubber gasket. This helps it seal.
Screw the new filter on by hand. Turn it clockwise until the gasket touches. Then give it another three-quarter turn. Don’t over-tighten it.
Go back to the drain plug. Clean it with a rag and check its washer. Put the plug back in the hole and tighten it with your wrench. Don’t strip the threads.
Adding the New Oil Correctly
Now it’s time for the fresh oil. Find the oil fill cap on top of the engine. It often says “Oil” on it or has a picture of an oil can.
Place your funnel in the fill hole. This is a key part of learning how to change oil on a Craftsman snowblower. The funnel prevents spills.
Pour in about three-quarters of the oil your manual says it holds. For most Craftsman snowblowers, this is around 18-20 ounces. Go slow.
Wait a minute for the oil to settle in the pan. Then check the dipstick. Pull it out, wipe it clean, put it back in, and pull it out again to read it.
The oil level should be between the “Low” and “Full” marks. Add a little more oil if it’s too low. Check the dipstick after each small addition.
Stop when the oil level is at the “Full” mark. Do not overfill it. Too much oil can cause foaming and poor lubrication, which hurts the engine.
Screw the oil fill cap back on tightly. Wipe up any spills on the engine with a rag. A clean engine makes it easier to spot future leaks.
How Often Should You Change the Oil?
Check your owner’s manual first. It has the official schedule from the maker. This is your best guide for your specific model.
A common rule is once per season. Do it at the end of winter before you store the machine. This gets rid of acidic byproducts that sit all summer.
Some people like to change it at the start of the season too. This gives you fresh oil for the hard work ahead. It’s a bit of overkill but it works.
If you use your snowblower a lot, think about hours of use. After every 25-50 hours of run time is a good interval for an oil change. Keep a log.
The type of oil matters for change intervals. Synthetic oil lasts longer than conventional oil. It can often go for two seasons with light use.
Your environment plays a role too. Dusty or sandy conditions make oil dirty faster. You might need to change it more often in those areas.
When in doubt, change it. Oil is cheap. Engines are not. An extra oil change each year costs very little but gives you big peace of mind.
Common Mistakes to Avoid
Don’t forget to change the filter. Some people just drain and refill. The old filter holds a lot of dirty oil and grit that goes right back into your clean oil.
Avoid over-tightening the drain plug or filter. This can strip the threads or crush the filter gasket. Hand-tight plus a little more with a tool is enough.
Never use the wrong type of oil. The viscosity grade (like 5W-30) is important for cold starts. Using the wrong oil can lead to poor lubrication on a freezing morning.
Don’t skip warming up the engine first. Cold oil is thick and sticky. A lot of it will stay stuck in the engine if you don’t warm it up to thin it out.
Avoid mixing old and new oil. Let the old oil drain completely. Tilt the machine a bit if you have to, to get the last of it out of the pan.
Don’t guess on the oil amount. Always use the dipstick to check the level after filling. Overfilling is just as bad as underfilling for engine health.
Forgetting to recycle the old oil is a big mistake. Never pour it on the ground or in the trash. Most auto parts stores will take it for free.
Tips for an Easier Oil Change
Lift the front of the snowblower onto a block of wood. This tilts the engine back slightly. It helps the old oil pool near the drain plug for a better drain.
Write the date and engine hours on the new filter with a marker. This helps you remember when you did the job. It’s a simple tracking trick.
Keep a dedicated “snowblower oil change kit.” Put a fresh filter, a jug of oil, a funnel, and a pack of rags in a box. Store it with your machine.
Take a picture of the oil fill cap and drain plug before you start. This helps you remember where everything goes if you get distracted mid-job.
Use a piece of cardboard as a work mat. It catches drips and gives you a clean place to set your tools. Just toss it when you’re done.
If the drain plug is stuck, don’t force it. Tap the wrench handle gently with a rubber mallet to break the seal. Forcing it can round off the bolt head.
After you add new oil, run the engine for a minute. Then check for leaks around the filter and drain plug. It’s easier to fix a leak now than later.
What to Do With the Old Oil
You must dispose of old oil properly. It is bad for the environment. It can pollute soil and water if you just dump it out.
Pour the oil from your drain pan into an empty, clean jug. A used milk jug or the bottle from your new oil works well. Seal the lid tightly.
Take your used oil to a recycling center. Many auto parts stores like AutoZone or O’Reilly Auto Parts accept it for free. Call ahead to check.
Some towns have household hazardous waste collection days. They will take your used oil and filter. Check your local government’s website for dates.
Never mix oil with other fluids like antifreeze or gasoline. This makes it impossible to recycle. It has to go to a special facility.
The old oil filter needs recycling too. Punch a hole in the dome to let the oil inside drain into your pan. Then put the filter in a plastic bag for recycling.
Proper disposal is the final, responsible step in learning how to change oil on a Craftsman snowblower. It closes the loop on the job the right way.
Frequently Asked Questions
How often should I change the oil in my Craftsman snowblower?
Once per season is a good rule. Do it at the end of winter before storage. If you use it a lot, check the manual for an hourly schedule.
