Spring is in the air, and that means it’s time to dust off your push lawn mower and get your yard looking its best. But before you fire it up, it’s important to make sure your mower is in good working order. One crucial maintenance task is changing the oil. But how often should you do it? That’s the question we’ll be answering in this comprehensive guide.
We’ll delve into the importance of regular oil changes, explore the factors that influence oil change frequency, and provide you with a clear understanding of when it’s time to swap out the old oil for fresh lubricant. We’ll also cover the essential steps involved in changing the oil yourself, ensuring you can keep your mower running smoothly throughout the season.
The Importance of Regular Oil Changes
Your lawn mower’s engine relies on oil for lubrication, cooling, and protection against wear and tear. As the engine runs, the oil circulates, picking up debris and breaking down. Over time, this contaminated oil loses its ability to effectively lubricate and cool the engine, leading to:
- Increased friction and wear: Without proper lubrication, engine parts rub against each other, causing excessive wear and reducing engine performance.
- Overheating: Contaminated oil loses its heat-transferring capabilities, leading to engine overheating and potential damage.
- Engine damage: Ultimately, neglecting oil changes can lead to serious engine problems, requiring costly repairs or even replacement.
How Often Should You Change the Oil?
There’s no one-size-fits-all answer to this question. The frequency of oil changes depends on several factors, including:
1. Engine Size and Type
- Smaller engines: Typically require less frequent oil changes compared to larger engines.
- Four-stroke engines: Generally need oil changes more frequently than two-stroke engines, as they use oil for lubrication and cooling.
2. Mower Usage and Operating Conditions
- Frequent use: Mowers used regularly, especially in hot or dusty conditions, require more frequent oil changes.
- Type of mowing: Mowing thick, tall grass can strain the engine, necessitating more frequent oil changes.
- Terrain: Mowing on hilly or uneven terrain puts extra stress on the engine, requiring more frequent oil changes.
3. Oil Type and Quality
- Synthetic oil: Provides longer protection and can be used for extended periods between oil changes.
- Conventional oil: Needs to be changed more frequently compared to synthetic oil.
4. Manufacturer Recommendations
Always refer to your mower’s owner’s manual for specific recommendations regarding oil type and change frequency.
General Guidelines for Oil Change Frequency:
- New Mowers: Change the oil after the first 5 hours of operation.
- Regular Use: Change the oil every 25 hours of use, or every 1-2 months if you mow frequently.
- Infrequent Use: Change the oil at least once per year, even if you haven’t used the mower extensively.
- Heavy Use: Consider changing the oil more frequently than the above guidelines, especially if you mow in challenging conditions.
How to Change the Oil in Your Push Lawn Mower
Once you’ve determined that it’s time for an oil change, you can follow these steps:
1. Gather Supplies
You’ll need:
- New oil: Refer to your owner’s manual for the recommended oil type and viscosity.
- Oil filter: If your mower has an oil filter, make sure you have a new one.
- Oil drain pan: A container to collect the used oil.
- Wrench or socket: To loosen the drain plug.
- Gloves: To protect your hands from the oil.
- Rag: To wipe up any spills.
2. Prepare the Mower
- Park the mower on a level surface. Make sure the engine is cold and has been off for at least 30 minutes.
- Remove the spark plug wire. This will prevent accidental starting.
3. Drain the Old Oil
- Locate the oil drain plug. It’s usually located at the bottom of the engine.
- Place the drain pan underneath the plug.
- Carefully loosen the drain plug. Be sure to hold it as you loosen it, as it may come out quickly and cause a mess.
- Allow the oil to drain completely. This may take a few minutes.
4. Change the Oil Filter (if applicable)
- Locate the oil filter. It’s typically attached to the side of the engine.
- Remove the old filter. You may need to use a filter wrench for this step.
- Install the new filter. Make sure the filter is securely tightened, but avoid overtightening.
5. Add New Oil
- Locate the oil fill hole. It’s usually located near the top of the engine.
- Pour the new oil into the fill hole. Refer to your owner’s manual for the correct amount.
- Check the oil level. Use the dipstick to check the oil level and add more oil if necessary.
6. Reinstall the Drain Plug
- Tighten the drain plug securely. But avoid overtightening.
7. Clean Up
- Dispose of the used oil properly. Never pour it down the drain or on the ground. Check with your local municipality for disposal options.
- Wipe up any spills. Clean the area around the mower with a rag.
8. Reattach the Spark Plug Wire
- Make sure the spark plug wire is securely connected. Now you’re ready to start the mower.
Important Notes:
- Always wear safety glasses and gloves when working with oil and tools.
- Handle the used oil carefully. It can be a fire hazard if not disposed of properly.
- Check the oil level regularly. Especially after using the mower for a longer period.
- Replace the oil filter at least every 3 oil changes. Even if your mower doesn’t have an oil filter, it’s a good idea to clean the oil screen or strainer at least every 2-3 oil changes.
