How to Check the Oil Level on A Poulan Pro Lawn Mower

Safety First: Before you start, make sure your Poulan Pro lawn mower is on a flat and level surface. Ensure the engine is turned off and the spark plug wire is disconnected to prevent accidental starting.

Locate the Dipstick: The oil dipstick is usually situated on the side of the engine. It is a long, thin metal rod with a T-shaped or L-shaped handle that allows you to grip and pull it out.

Wipe the Dipstick: Using a clean cloth or paper towel, wipe the dipstick clean to remove any oil residue. This ensures an accurate reading.

Insert the Dipstick: Carefully reinsert the dipstick into the oil filler neck (where you pour the oil). Push it in until it’s fully seated.

Retrieve the Dipstick: Remove it to check the oil level after reinserting it. Hold it horizontally to get an accurate reading.

Observe the Oil Level: You’ll notice two marks or indicators on the dipstick. One is typically labeled “Full,” and the other is labeled “Add” or “Low.” The oil level should fall between these two marks. If the oil level is near or at the “Full” mark, it’s adequate. You need to add more oil if it’s closer to the “Add” or “Low” mark.

Add Oil (If Necessary): If the oil level is low, carefully pour the appropriate type and amount of oil into the oil filler neck. Be cautious not to overfill, as excess oil can lead to engine problems.

Recheck the Level: After adding oil, repeat the process. Reinsert the dipstick, then remove it to check the oil level again. Ensure it now falls within the “Full” and “Add” marks.

Secure the Dipstick: Once satisfied with the oil level, securely reinsert the dipstick into the oil filler neck and ensure it’s fully seated.

Clean Up: Wipe any spilled oil and residue from the engine and dipstick, and securely close the oil filler cap.

Reason You Need Oil for Your Mower


Proper oil is essential for your mower’s engine because it lubricates all its moving parts. As these components work together, they generate friction and heat. 

Proper lubrication reduces this friction, preventing premature wear and tear ensuring smooth and efficient operation, ultimately extending the life of your mower.

Heat Dissipation

Mower engines generate a significant amount of heat during operation. Engine oil plays a crucial role in dissipating this heat by absorbing it from the engine’s components and carrying it away.

Without proper cooling from the oil, your engine may overheat, leading to performance issues and potential damage.


Engine oil also helps clean the internal components of your mower’s engine. It carries away dirt, debris, and small particles that can accumulate during operation. 

This cleansing action keeps the engine clean and prevents the formation of harmful deposits, which can hinder performance and efficiency.


Oil creates a seal between the engine’s piston rings and the cylinder walls. This seal prevents combustion gases from escaping into the crankcase and maintains proper compression within the engine. 

Without this seal, your mower could lose power, consume more fuel, and suffer reduced performance.


Oil not only lubricates and cools but also acts as a preservative. It prevents corrosion and rust formation on engine components, especially during periods of inactivity. 

Properly maintaining your mower’s oil level helps preserve the engine, ensuring it starts reliably when needed.


Adequate oil levels and quality contribute significantly to your mower’s overall performance. Engines running with the right type and amount of oil deliver consistent power, smooth operation, and cleaner emissions. 

Neglecting oil maintenance can reduce performance, increase emissions, and a less enjoyable mowing experience.

Fuel Efficiency

Engine oil indirectly impacts fuel efficiency. A well-lubricated engine with clean oil runs more efficiently, requiring less fuel to perform the same work. 

Neglecting oil changes or using improper oil can increase friction and reduce efficiency, leading to higher fuel consumption and operating costs. 

Regular oil maintenance can save money on fuel in the long run while also ensuring the best results for your engine performance.
