- Fresh oil (SAE 30 or 10W-30)
- Oil filter (if needed)
- Oil drain pan
- Wrench
- Rag or paper towels
- Funnel
- Gloves
Step-by-Step Guide
Step 1: Warm Up The Engine
Start the mower and let it run for a few minutes. This warms up the oil. Warm oil flows out easily.
Step 2: Disconnect The Spark Plug
Turn off the engine. Remove the spark plug wire. This prevents the mower from starting by accident.
Step 3: Drain The Old Oil
Place the oil drain pan under the mower. Remove the oil fill cap. Tilt the mower to drain the oil into the pan. Be careful not to spill. Let all the oil drain out.
Step 4: Replace The Oil Filter (if Needed)
If your mower has an oil filter, now is the time to change it. Use a wrench to remove the old filter. Wipe the area clean. Install the new filter. Tighten it by hand.
Step 5: Add New Oil
Use a funnel to add new oil. Pour slowly to avoid spills. Fill to the recommended level. Check the dipstick to ensure the right amount.
Step 6: Reconnect The Spark Plug
Put the spark plug wire back in place. Make sure it is secure.
Step 7: Check For Leaks
Start the mower and let it run for a few minutes. Check for oil leaks. If there are no leaks, you are done.
Tips for a Smooth Oil Change
- Always use the oil type recommended by Toro.
- Change the oil filter regularly.
- Dispose of old oil properly. Take it to a recycling center.
Why Regular Oil Changes are Important
Regular oil changes keep the engine in good condition. Clean oil lubricates the engine parts. This reduces wear and tear. It also improves the mower’s performance.
Common Mistakes to Avoid
- Not warming up the engine before draining the oil.
- Overfilling or underfilling the oil.
- Forgetting to replace the oil filter.
- Not checking for leaks after adding new oil.
