Procedure of changing engine oil?

1. Gather necessary materials: new engine oil, oil filter, oil filter wrench, oil drain pan, funnel, and wrench or socket set.

2. Park the vehicle on a level surface and allow the engine to cool down.

3. Locate the oil drain plug underneath the vehicle. Place the oil drain pan underneath the plug to catch the old oil.

4. Use a wrench or socket set to loosen the drain plug and carefully remove it. Allow the old oil to drain completely into the oil drain pan.

5. While the oil is draining, locate the oil filter. Use an oil filter wrench to remove the old oil filter. Be sure to have the oil drain pan underneath to catch any remaining oil.

6. Before installing the new oil filter, apply a small amount of new engine oil to the rubber gasket on the filter. This will help create a proper seal.

7. Install the new oil filter by hand, tightening it until it is snug. Do not over-tighten the filter.

8. Once the old oil has finished draining, replace the drain plug and tighten it securely.

9. Use a funnel to pour the new engine oil into the engine. Refer to the owner's manual for the correct type and amount of oil needed.

10. Start the engine and let it run for a few minutes to circulate the new oil. Check for any leaks around the oil drain plug and oil filter.

11. Turn off the engine and check the oil level using the dipstick. Add more oil if necessary to reach the correct level.

12. Dispose of the old oil and filter properly at a recycling center or auto parts store.

13. Record the date and mileage of the oil change for future reference.

Materials:

- New engine oil (refer to your vehicle's specifications)
- New oil filter
- Drain pan
- Funnel
- Wrench or socket set
- Rags or gloves

Procedure:

1. Safety Precautions:

- Park the vehicle on a level surface and engage the parking brake.
- Allow the engine to cool for at least 30 minutes to prevent burns.

2. Locate the Drain Plug:

- Crawl under the vehicle and locate the oil drain plug on the oil pan. It is usually a 17mm or 19mm bolt.

3. Prepare to Drain the Oil:

- Place the drain pan under the oil drain plug.
- Loosen the drain plug slightly using a wrench or socket.

4. Drain the Oil:

- Carefully remove the drain plug completely and allow the oil to drain into the pan.
- Allow all the oil to drain out, which may take several minutes.

5. Replace the Drain Plug:

- Clean the drain plug and the threads on the oil pan.
- Apply a small amount of thread sealant to the drain plug.
- Tighten the drain plug to the specified torque (refer to your vehicle's manual).

6. Locate and Remove the Oil Filter:

- Find the oil filter, which is usually located near the engine.
- Use an oil filter wrench or socket to loosen the filter.
- Carefully remove the filter and discard the old oil.

7. Apply Oil to the New Filter:

- Apply a thin layer of clean oil to the rubber gasket on the new oil filter.

8. Install the New Filter:

- Hand-tighten the new oil filter onto the filter housing.
- Use the oil filter wrench or socket to tighten the filter to the specified torque (refer to your vehicle's manual).

9. Add New Oil:

- Using a funnel, pour the new engine oil into the engine.
- Refer to your vehicle's manual for the correct amount of oil required.

10. Check the Oil Level:

- Insert the oil dipstick and remove it to check the oil level.
- The oil level should be between the "Min" and "Max" marks on the dipstick.

11. Start the Engine and Check for Leaks:

- Start the engine and let it run for a few minutes.
- Check for any leaks around the drain plug or oil filter.

12. Reset the Maintenance Indicator (if applicable):

- Some vehicles have a maintenance indicator that needs to be reset after an oil change. Refer to your vehicle's manual for specific instructions.

Tips:

- Use the correct oil type and viscosity for your vehicle.
- Change the oil filter every time you change the oil.
- Check the oil level regularly, especially before long trips.
- Dispose of used oil and filters properly at a recycling facility.
