The warm weather is here, and your Craftsman lawnmower is probably itching to get back to work. But before you fire it up, you need to make sure you’re using the right oil. Choosing the wrong oil can lead to engine problems, costly repairs, and even premature failure. This guide will walk you through the different types of oil, how to choose the right one for your mower, and how to change your oil properly.
Short Answer:
The best oil for your Craftsman lawn mower depends on the engine type and the climate you live in. Most Craftsman mowers use four-stroke engines that require SAE 30 or 10W-30 oil during the summer and 5W-30 oil during the winter.
Understanding Oil Types: The Basics
Before we dive into the specifics of Craftsman lawnmowers, let’s clarify the different types of oil you might encounter:
- SAE (Society of Automotive Engineers) Viscosity: This refers to the oil’s thickness or resistance to flow at different temperatures. Higher numbers indicate thicker oil.
- Single-Grade Oils: These oils have a single viscosity rating, like SAE 30. They work best in consistent temperatures.
- Multi-Grade Oils: These oils have two viscosity ratings separated by a “W” (for winter). For example, 10W-30 is thinner at colder temperatures (10W) but thicker at hotter temperatures (30).
- Synthetic vs. Conventional Oil: Synthetic oils are created in a lab and offer better performance at high temperatures and in extreme weather conditions. Conventional oils are derived from crude oil and are typically less expensive.
How to Choose the Right Oil for Your Craftsman Lawn Mower
Choosing the correct oil for your Craftsman lawnmower depends on a few key factors:
1. Engine Type
- Four-Stroke Engines: These are the most common type of engine in lawnmowers. They require a dedicated oil that lubricates the engine’s moving parts.
- Two-Stroke Engines: These engines use a mixture of gasoline and oil for lubrication. You’ll need to consult your owner’s manual to determine the correct oil-to-gas ratio for your mower.
2. Climate
- Warm Weather: During summer, use a single-grade SAE 30 oil or a multi-grade oil like 10W-30.
- Cold Weather: In colder months, use a multi-grade oil like 5W-30 to ensure proper lubrication at lower temperatures.
3. Your Owner’s Manual
The most reliable source of information is your Craftsman lawnmower’s owner’s manual. It will specify the exact oil type and viscosity recommended by the manufacturer for your particular model.
What Oil is Recommended for Craftsman Lawn Mower Engines?
As mentioned previously, most Craftsman lawnmowers use four-stroke engines. Here are some general guidelines:
1. Four-Stroke Engines
- SAE 30: Recommended for warm weather conditions (above 32 degrees Fahrenheit).
- 10W-30: Suitable for a wide range of temperatures, from mild to warm.
- 5W-30: Preferred for colder weather conditions (below 32 degrees Fahrenheit).
2. Two-Stroke Engines
- Consult Your Owner’s Manual: Two-stroke engines require a specific blend of oil and gasoline. Refer to your owner’s manual for the correct oil-to-gas ratio and the recommended oil type.
Tips for Using Oil in Your Craftsman Lawn Mower
- Check Oil Level Regularly: Before each use, check the oil level using the dipstick.
- Change Oil Regularly: Refer to your owner’s manual for the recommended oil change interval, but it’s generally recommended to change the oil every 25 hours of operation or at least once a year.
- Use Quality Oil: Choose high-quality oil from a reputable brand.
- Store Oil Properly: Store oil in a cool, dry place to prevent deterioration.
How to Change Your Craftsman Lawn Mower Oil
Here’s a step-by-step guide on how to change the oil in your Craftsman lawnmower:
- Gather Your Supplies: You’ll need a new oil filter, fresh oil, a wrench or socket for the drain plug, an oil catch pan, a funnel, and gloves.
- Warm Up the Engine: Run the mower for a few minutes to warm up the oil, making it easier to drain.
- Locate the Drain Plug: The drain plug is typically located at the bottom of the engine block.
- Place Catch Pan: Position the oil catch pan underneath the drain plug.
- Remove the Drain Plug: Using your wrench or socket, carefully loosen the drain plug and allow the oil to drain into the catch pan.
- Replace the Drain Plug: Once the oil has drained, tighten the drain plug securely.
- Remove the Oil Filter: If your mower has an oil filter, remove it using the correct filter wrench.
- Install New Oil Filter: Lubricate the new oil filter’s gasket with a small amount of clean oil.
- Add New Oil: Using your funnel, pour the recommended amount of fresh oil into the engine’s filler neck.
- Check Oil Level: After adding oil, check the level using the dipstick.
Conclusion: Choosing the Right Oil Keeps Your Mower Running Smoothly

FAQ
What kind of oil should I use in my Craftsman lawnmower?
For most Craftsman lawnmowers, you should use SAE 30 oil. This is a common type of oil that is designed for gasoline engines and is generally suitable for most lawnmowers. However, it’s always best to consult your owner’s manual to confirm the specific type of oil recommended for your model.
If you can’t find your manual, you can also check the dipstick in your mower. It will often specify the type and weight of oil that is recommended for your engine. Be sure to use the appropriate oil weight for the temperature in your area.
Can I use car oil in my Craftsman lawnmower?
While you can technically use car oil in your Craftsman lawnmower, it’s not always the best idea. Car oils are typically designed for higher RPM engines and may not provide the same level of protection for your lawnmower’s engine.
It’s best to stick with oil that is specifically designed for small engines, like lawnmower oil. This will ensure that your engine is properly lubricated and protected.
How much oil should I put in my Craftsman lawnmower?
The amount of oil you need to put in your Craftsman lawnmower will vary depending on the model. You should always consult your owner’s manual for the specific amount of oil that is recommended.
Typically, lawnmowers have a dipstick that indicates the full and low oil levels. Make sure you add oil until it reaches the “full” mark on the dipstick. Never overfill the crankcase, as this can damage your engine.
What happens if I use the wrong oil in my Craftsman lawnmower?
Using the wrong type of oil in your Craftsman lawnmower can lead to a variety of problems, including:
- Reduced engine performance.
- Increased engine wear and tear.
- Engine damage.
It’s important to always use the recommended type and weight of oil for your lawnmower to ensure that your engine is properly lubricated and protected.
When should I change the oil in my Craftsman lawnmower?
The frequency with which you should change the oil in your Craftsman lawnmower will depend on factors such as how often you use it and the type of oil you’re using.
Generally, it’s recommended to change the oil every 25 hours of use or at least once per season. You should also check the oil level frequently and top it off as needed.
What is the best time of year to change the oil in my Craftsman lawnmower?
The best time to change the oil in your Craftsman lawnmower is at the beginning of the mowing season. This will help ensure that your engine is properly lubricated and ready for the season ahead.
If you use your lawnmower frequently throughout the year, you may need to change the oil more often. It’s always best to consult your owner’s manual for the specific oil change recommendations for your model.
What is the difference between synthetic and conventional oil for my Craftsman lawnmower?
Synthetic oil is made from chemically engineered molecules and can provide several benefits over conventional oil. It tends to last longer, perform better in extreme temperatures, and offer better engine protection.
Conventional oil is made from crude oil and is less expensive than synthetic. However, it doesn’t offer the same level of protection or performance. You can use either type of oil in your Craftsman lawnmower, but it’s important to choose the right type based on your individual needs and preferences.
