How to Change the Oil In A Push Lawn Mower?

16 minutes read

Changing the oil in a push lawn mower is an essential maintenance task that helps to keep the engine running smoothly and extend its lifespan. Here is a step-by-step guide on how to change the oil in a push lawn mower:

  1. Safety first: Before starting any maintenance work, ensure that the mower is turned off and the spark plug wire is disconnected to prevent accidental starts.
  2. Locate the oil drain plug: Look for a drain plug at the base or underside of the engine. It is usually a square or hexagonal bolt.
  3. Position an oil container: Place a suitable container capable of holding the old oil under the mower's drain plug.
  4. Drain the oil: Unscrew the drain plug using a wrench or socket and allow the old oil to drain completely. Tilting the mower slightly can help drain the oil more effectively.
  5. Remove the oil filler plug/cap: Locate the oil filler plug or cap on the top of the engine. Unscrew it to provide a vent as the oil drains.
  6. Replace the drain plug: After ensuring all the oil has drained out, wipe off any debris from the drain plug, then reinsert it and tighten it securely.
  7. Prepare new oil: Refer to the lawn mower's manual to determine the recommended oil type and quantity. Acquire the specified oil for your mower.
  8. Add fresh oil: Slowly pour the appropriate amount of new oil into the oil filler opening, ensuring it reaches the correct level. Avoid overfilling as it can cause engine damage.
  9. Check oil level: Insert the oil dipstick (if applicable) or use the oil sight window (found on some mowers) to check the oil level. Add more oil if required but be cautious not to exceed the recommended level.
  10. Replace the oil filler plug/cap: Once the oil level is correct, reattach and tighten the oil filler plug or cap securely.
  11. Clean up: Wipe off any oil spills or drips on the mower to prevent a mess and ensure proper lubrication.
  12. Dispose of old oil responsibly: Transfer the old oil from the container to a suitable, sealable container for recycling or proper disposal at a local recycling center.


By following these steps, you can successfully change the oil in your push lawn mower, promoting its longevity and optimal performance. Remember to consult the lawn mower's manual for specific instructions and guidelines related to your model.

What is the role of oil in the engine of a push lawn mower?

The role of oil in the engine of a push lawn mower is to provide lubrication and reduce friction between moving parts. It helps keep the engine running smoothly and prevents it from overheating by reducing heat generated from friction. Additionally, oil also helps to clean the engine by trapping dirt and debris, preventing them from clogging the machine. Overall, oil plays a crucial role in maintaining the engine's performance and prolonging its life.


How to choose the correct oil viscosity for a push lawn mower?

Choosing the correct oil viscosity for a push lawn mower depends on various factors, such as the climate you live in and the temperature range in which you will be using the mower. Here are some steps to help you choose the right viscosity for your push lawn mower:

  1. Consult the owner's manual: The manufacturer of your lawn mower will typically recommend a specific viscosity range for the engine oil. The manual will provide information on the recommended viscosity, such as SAE 30 or SAE 10W-30.
  2. Consider the climate: If you live in an area with extremely hot temperatures, you may want to use a slightly higher viscosity oil to provide better protection against heat. Conversely, if you are in a very cold climate, you may need a lower viscosity oil to ensure proper lubrication during cold starts.
  3. Understand oil viscosity ratings: Viscosity ratings are represented by numbers such as SAE 10, SAE 30, or SAE 40. The lower number indicates a lower viscosity and is suitable for colder temperatures, while the higher number indicates a higher viscosity and is suitable for hotter temperatures.
  4. Check for multi-viscosity oils: Some oils have dual viscosities listed, such as SAE 10W-30. The "W" stands for winter, and the first number represents the oil's viscosity at colder temperatures, while the second number represents its viscosity at higher temperatures. Multi-viscosity oils provide more versatility for different temperature ranges.
  5. Consider synthetic oils: Synthetic oils generally provide better performance and protection compared to conventional oils. They offer reduced friction, better viscosity stability, and improved protection against engine wear. However, synthetic oils tend to be more expensive.
  6. Seek professional advice: If you are still unsure about which oil viscosity to use for your push lawn mower, consult a lawn mower specialist or the manufacturer's customer support for specific recommendations based on your mower's specifications and your geographical location.


By following these steps and considering the climate and manufacturer's recommendations, you can choose the correct oil viscosity for your push lawn mower and ensure optimal performance and durability.


What is the difference between regular engine oil and synthetic oil for a push lawn mower?

The main difference between regular engine oil and synthetic oil for a push lawn mower lies in their composition and performance characteristics:

  1. Composition: Regular engine oil, also known as conventional or mineral oil, is derived from crude oil and contains a blend of base oils and additives. Synthetic oil, on the other hand, is made through a chemical process and designed to have a more consistent and uniform molecular structure.
  2. Viscosity: Synthetic oil typically has a more consistent viscosity across a wide range of temperatures compared to regular oil. This means it will flow more easily during both cold starts and high-temperature conditions, providing better lubrication and protection.
  3. Performance: Synthetic oil offers superior lubrication and wear protection due to its smoother molecular structure. It has improved resistance to oxidation, thermal breakdown, and sludge formation, enhancing the overall lifespan of the engine. Synthetic oil also tends to have better detergency, keeping the engine cleaner by preventing deposit build-up.
  4. Price: Synthetic oil generally costs more than regular oil due to its advanced manufacturing process and superior performance characteristics.


When choosing between regular engine oil and synthetic oil for a push lawn mower, consider factors such as the mower's operating conditions, frequency of use, and manufacturer recommendations. While synthetic oil offers enhanced performance and protection, regular oil may still suffice for casual or less-demanding use. Always consult the owner's manual or reach out to the manufacturer for specific oil recommendations for your lawn mower.
