The roar of your Craftsman lawn mower signals the start of a beautiful, manicured lawn. But like any engine, it needs regular maintenance to keep running smoothly. One of the most important tasks is changing the oil, and it’s a job you can easily do yourself, saving money and extending the life of your mower.
This article will walk you through the process step by step, providing clear instructions and helpful tips. You’ll learn how to choose the right oil, properly drain the old oil, refill the engine, and dispose of the used oil responsibly.
A Quick Overview of Changing Oil in a Craftsman Lawn Mower
Changing your Craftsman lawn mower oil involves draining the old oil, refilling the crankcase with fresh oil, and disposing of the used oil properly. It’s a simple process that typically takes less than 30 minutes.
Preparing for the Oil Change
Before you begin, gather the following materials:
- New oil: Consult your mower’s manual to determine the correct type and viscosity of oil.
- Oil drain pan: A large pan designed for collecting used oil.
- Oil filter wrench (optional): If your mower has an oil filter, you’ll need a wrench to remove it.
- Rag: To clean up any spills.
- Gloves: To protect your hands from oil.
Choosing the Right Oil
The type of oil you need will depend on the age and model of your Craftsman lawn mower. Consult your owner’s manual for the recommended oil type and viscosity.
Typically, Craftsman mowers use 4-stroke engine oil. Look for oils that are labeled “SAE 30” or “SAE 10W30” for general use.
Locating the Oil Drain Plug and Fill Cap
Before starting, locate the oil drain plug and the oil fill cap on your mower. They are usually found on the bottom of the engine block.
The oil drain plug is typically a hexagonal or square-shaped bolt. The oil fill cap is usually a round cap with a dipstick.
Draining the Old Oil
- Warm up the engine: Run the mower for a few minutes to warm up the oil, making it flow more easily.
- Place the drain pan: Position the oil drain pan directly under the drain plug.
- Remove the drain plug: Use a wrench to loosen and remove the drain plug. Be careful as the oil will be hot.
- Let the oil drain: Allow all the oil to drain completely into the pan. This may take a few minutes.
- Replace the drain plug: Once the oil has drained, tighten the drain plug securely.
Tips for Efficient Draining
- For extra thorough draining, remove the spark plug to allow air into the crankcase.
- If the drain plug is stuck, try using a pipe wrench or a penetrating oil like WD-40.
- Always wear gloves to protect your hands from hot oil.
Changing the Oil Filter (If Applicable)
Many Craftsman mowers have an oil filter that needs to be changed with each oil change.
- Locate the oil filter: The oil filter is usually located near the top of the engine block, often close to the oil fill cap.
- Loosen the filter: Use an oil filter wrench to loosen the filter. It may be necessary to turn the filter counter-clockwise to remove it.
- Remove the filter: Once the filter is loose, you can remove it by hand.
- Install the new filter: Apply a thin layer of oil to the rubber gasket of the new filter and screw it onto the filter housing. Do not overtighten.
Tips for Changing the Oil Filter
- Always dispose of the old filter properly.
- If you’re having trouble removing the filter, try using a filter wrench that has a rubber grip.
- Avoid getting oil on the filter’s gasket, as this can cause a leak.
Refilling with New Oil
- Add the new oil: Carefully pour the recommended amount of new oil into the oil fill cap. Refer to your owner’s manual for the exact amount.
- Check the oil level: Once you’ve added the oil, use the dipstick to check the oil level. The oil level should be at the full mark on the dipstick.
- Clean up any spills: Wipe up any oil spills with a rag.
Tips for Refilling with New Oil
- Pour the oil slowly to avoid overfilling the crankcase.
- Always use the type and viscosity of oil recommended by the manufacturer.
- If you overfill the crankcase, you can drain some of the oil using the drain plug.
Disposing of the Used Oil
It’s important to dispose of used oil responsibly to protect the environment.
- Allow the oil to cool: Let the oil cool completely in the drain pan before disposing of it.
- Find a proper disposal location: Contact your local waste management facility or recycling center to find out where you can dispose of used oil. Many auto parts stores and garages accept used oil for free.
- Never pour used oil down the drain or into the ground: This can contaminate water sources and harm wildlife.
Alternative Oil Disposal Options
- Use it for other purposes: Some people use used oil for tasks like cleaning metal parts or as a rust preventative.
- Recycle it: Many recycling centers will accept used oil for processing.
Important Maintenance Tips
- Change oil regularly: Check your owner’s manual for the recommended oil change interval for your specific model. Typically, oil changes are recommended every 25-50 hours of operation.
- Keep an eye on the oil level: Check the oil level frequently, especially after mowing.
- Inspect the oil for signs of contamination: If the oil is discolored, has a milky appearance, or contains metal shavings, it may indicate a problem with the engine.

FAQ
Q1: Why is it important to change the oil in my Craftsman lawn mower?
A: Changing the oil in your Craftsman lawn mower is crucial for its longevity and performance. As the engine runs, the oil breaks down and collects debris, losing its ability to lubricate and cool the internal components. This can lead to excessive wear and tear, overheating, and ultimately, engine failure. Regular oil changes ensure your mower runs smoothly, efficiently, and lasts for years to come.
Q2: How often should I change the oil in my Craftsman lawn mower?
A: The frequency of oil changes depends on several factors, including how often you use the mower and the type of oil used. Generally, you should change the oil every 25 hours of operation or at the beginning of each mowing season, whichever comes first. However, always refer to your owner’s manual for the recommended oil change interval specific to your Craftsman model.
Q3: What type of oil should I use for my Craftsman lawn mower?
A: The best oil for your Craftsman lawn mower is specified in your owner’s manual. Most Craftsman lawn mowers use SAE 30 oil, which is a thicker oil designed for high-temperature applications. You can also use a multi-grade oil like SAE 10W-30, which provides better cold-weather performance but might not be as suitable for high temperatures.
Q4: What tools do I need to change the oil in my Craftsman lawn mower?
A: You’ll need a few basic tools to change the oil in your Craftsman lawn mower. These include:
* A wrench or socket that fits the oil drain plug
* A drain pan or container to collect the used oil
* A funnel for pouring in the new oil
* A rag or paper towels to clean up spills
* A new oil filter (if your mower has one)
Q5: What steps should I take to dispose of the used oil properly?
A: Used motor oil is a hazardous waste and needs to be disposed of properly. Do not pour it down the drain or into the trash. Instead, take it to a local auto parts store or recycling center that accepts used motor oil. They will often have a container available for collection.
Q6: What if I don’t have the right tools or am unsure about the process?
A: If you’re not comfortable changing the oil in your Craftsman lawn mower yourself, you can always take it to a qualified mechanic or lawn care professional. They can perform the oil change quickly and safely, ensuring your mower is properly maintained.
Q7: Can I use a different type of oil if I can’t find the recommended one?
A: While you might be tempted to use a readily available oil if you can’t find the recommended type, it’s best to stick to the specifications in your owner’s manual. Using the wrong oil can damage your engine, leading to costly repairs in the long run. If you can’t find the recommended oil, contact a local lawn care equipment dealer or service center for assistance.
