Why Bother Changing Your Own Oil? (Besides Saving Money, of Course!)

Let's be honest, taking your mower to a shop for an oil change is convenient. But there are several compelling reasons to consider doing it yourself. First, you know exactly what kind of oil is going into your engine. No more wondering if they used the cheapest stuff on the shelf! You can choose a high-quality oil specifically formulated for small engines, ensuring optimal performance and protection.

Second, changing your own oil allows you to inspect your mower more closely. You might notice a loose belt, a worn tire, or another potential problem before it becomes a major issue. This proactive approach can save you time and money in the long run by preventing costly repairs. Plus, there's a certain satisfaction in knowing you're taking good care of your equipment.

Gathering Your Arsenal: Tools and Supplies You'll Need

Before you even think about touching your mower, gather everything you'll need. This will prevent frustrating interruptions and ensure a smooth oil change. Here's a checklist:

  • New Oil: Check your owner's manual for the correct oil type and capacity. Typically, a 10W-30 or 10W-40 oil designed for small engines is recommended. Don't skimp on quality! A good synthetic oil can provide superior protection.
  • New Oil Filter: Again, consult your owner's manual for the correct filter. Using the wrong filter can lead to problems.
  • Oil Filter Wrench: This specialized wrench makes removing the old filter much easier.
  • Wrench for the Drain Plug: The size will vary depending on your mower model.
  • Drain Pan: A wide, shallow pan is ideal for catching the old oil.
  • Funnel: For pouring the new oil into the engine.
  • Rags or Shop Towels: For cleaning up spills.
  • Gloves: To protect your hands.
  • Jack or Ramps (Optional): Depending on your mower model, raising it slightly might make accessing the drain plug easier. Always use caution and secure the mower properly if lifting it.
  • Owner's Manual: Your best resource for specific information about your mower.

Safety First! Preparing Your Bad Boy for the Procedure

Safety is paramount when working with machinery. Follow these precautions:

  • Let the Engine Cool Down: Never attempt to change the oil on a hot engine. Allow it to cool completely to avoid burns.
  • Park on a Level Surface: This ensures accurate oil drainage and prevents the mower from rolling.
  • Engage the Parking Brake: This is a simple but crucial safety measure.
  • Disconnect the Spark Plug Wire: This prevents accidental starting of the engine while you're working. Locate the spark plug and gently pull the wire off.
  • Wear Safety Glasses: Protect your eyes from splashes.

Let's Get Dirty: Draining the Old Oil

Now for the main event! Here's how to drain the old oil:

  1. Locate the Drain Plug: Consult your owner's manual if you're unsure of its location. It's typically on the bottom of the engine.
  2. Position the Drain Pan: Place the drain pan directly under the drain plug.
  3. Loosen the Drain Plug: Use the correct wrench to loosen the drain plug. Be careful not to overtighten it.
  4. Remove the Drain Plug: Carefully unscrew the drain plug by hand, allowing the old oil to flow into the drain pan. Be prepared for a steady stream of oil!
  5. Let it Drain Completely: Allow the oil to drain completely, which may take 15-30 minutes. You can gently tilt the mower to help get out the last bit of oil.
  6. Inspect the Drain Plug: Check the drain plug for any damage. Replace it if necessary.
  7. Reinstall the Drain Plug: Once the oil has drained completely, clean the drain plug and reinstall it. Tighten it securely, but don't overtighten it. Consult your owner's manual for the correct torque specification.

Filter Frenzy: Removing and Replacing the Oil Filter

Next up is the oil filter. Here's how to tackle it:

  1. Locate the Oil Filter: Again, consult your owner's manual if you're unsure of its location.
  2. Position the Drain Pan: Place the drain pan under the oil filter to catch any oil that spills.
  3. Loosen the Oil Filter: Use the oil filter wrench to loosen the old oil filter.
  4. Remove the Oil Filter: Unscrew the oil filter by hand. Be prepared for some oil spillage!
  5. Prepare the New Oil Filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. This helps create a good seal.
  6. Install the New Oil Filter: Screw the new oil filter onto the engine by hand until the gasket makes contact with the engine. Then, tighten it another 1/2 to 3/4 turn. Consult your owner's manual for specific tightening instructions.
  7. Clean Up Any Spills: Use rags or shop towels to clean up any oil that spilled during the filter removal and installation process.

The Final Touch: Adding the New Oil

Almost there! Now it's time to replenish your mower's lifeblood:

  1. Locate the Oil Fill Cap: Consult your owner's manual if you're unsure of its location.
  2. Remove the Oil Fill Cap: Unscrew the oil fill cap.
  3. Insert the Funnel: Place the funnel into the oil fill opening.
  4. Pour in the New Oil: Slowly pour the new oil into the engine, using the funnel to avoid spills. Refer to your owner's manual for the correct oil capacity.
  5. Check the Oil Level: Use the dipstick to check the oil level. Add more oil if necessary, until the level reaches the "full" mark. Don't overfill!
  6. Replace the Oil Fill Cap: Screw the oil fill cap back on securely.

Double-Checking Your Work and Firing it Up!

Before you declare victory, take a moment to double-check everything:

  • Ensure the Drain Plug is Tight: Make sure the drain plug is securely tightened.
  • Ensure the Oil Filter is Tight: Make sure the oil filter is securely tightened.
  • Check for Leaks: Inspect around the drain plug and oil filter for any leaks.
  • Reconnect the Spark Plug Wire: Reconnect the spark plug wire.

Now, it's time to start your mower! Let it run for a few minutes and check again for leaks. If everything looks good, you're done!

Disposing of the Old Oil Responsibly

Used motor oil is a hazardous waste and should be disposed of properly. Never pour it down the drain or onto the ground! Most auto parts stores and recycling centers will accept used motor oil for free. Check with your local municipality for specific disposal guidelines.
