Step-by-Step Guide to Changing Oil

1. Prepare Your Car

• Park on a Level Surface: Ensure the car is parked on a flat surface to allow for proper drainage.
• Gather Tools and Materials: Have everything within reach before starting.

2. Warm Up the Engine

• Run the Engine: Start the engine and let it run for a few minutes to warm up the oil. Warm oil flows more easily, facilitating drainage.

3. Jack Up the Car

• Use Jack Stands: Place jack stands under the car for safety, ensuring it’s securely elevated.
• Locate Oil Drain Plug: Consult your car’s manual to locate the oil drain plug underneath the engine.

4. Drain the Old Oil

• Position Drain Pan: Place the oil drain pan directly under the oil drain plug.
• Loosen Drain Plug: Use a wrench to carefully loosen the drain plug, ensuring the pan is positioned to catch the oil.
• Let Oil Drain: Allow the old oil to drain completely into the pan.

5. Replace the Oil Filter

• Locate Oil Filter: The oil filter is typically located near the oil pan or on the side of the engine.
• Remove Old Oil Filter: Use an oil filter wrench to loosen and remove the old oil filter.
• Prepare New Oil Filter: Apply a thin layer of new oil to the rubber gasket of the new oil filter.
• Install New Oil Filter: Screw on the new oil filter by hand until snug. Do not overtighten.

6. Add New Oil

• Locate Oil Fill Cap: Remove the oil fill cap located on top of the engine.
• Use a Funnel: Place a funnel in the oil fill hole and pour in the recommended amount of new oil.
• Check Oil Level: Use the dipstick to check the oil level and add more if necessary. Be careful not to overfill.

7. Check for Leaks and Clean Up

• Tighten Drain Plug: Ensure the drain plug is securely tightened to prevent leaks.
• Check Oil Filter: Wipe any excess oil around the oil filter and ensure it’s properly installed.
• Dispose of Old Oil: Properly dispose of the old oil and filter at a recycling center or service station.

8. Lower the Car

• Remove Jack Stands: Carefully lower the car using the jack and remove the jack stands.

9. Dispose of Waste Responsibly

• Recycle: Take the used oil and filter to a recycling center that accepts automotive fluids.

Safety Precautions

• Cool Engine: Ensure the engine is cool before starting to avoid burns from hot components.
• Protective Gear: Wear gloves and safety glasses to protect against oil and debris.
• Stable Position: Use jack stands and never rely solely on a jack to support the car.

Maintenance Tips

• Follow Schedule: Refer to your car’s manual for recommended oil change intervals.
• Monitor Oil Levels: Regularly check oil levels between changes to ensure optimal engine performance.
