Solution

1. Preparation

Gather tools: oil filter wrench, socket set, oil catch pan, funnel, clean rags.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Drain Old Oil

Locate the oil drain plug: Underneath the vehicle, find the oil drain plug.
Remove the drain plug: Use a socket set to loosen and remove the drain plug. Allow the old oil to completely drain into the catch pan.
Replace the drain plug: Once the oil has drained, clean the drain plug and replace it, tightening it to the manufacturer’s specified torque.

3. Replace Oil Filter

Locate the oil filter: Find the oil filter, usually accessible from the top or bottom of the engine.
Remove the old oil filter: Use an oil filter wrench to unscrew the old filter. Be cautious of residual oil.
Install new oil filter: Apply a small amount of new oil to the rubber gasket of the new filter, then screw it into place by hand until snug, and tighten slightly more with a wrench.

4. Add New Oil

Choose the correct oil: Refer to the owner’s manual for the recommended oil type and viscosity.
Add new oil: Remove the oil fill cap on the top of the engine and use a funnel to pour in the new oil. Start with the recommended amount.
Check oil level: After adding oil, wait a few minutes, then check the oil level using the dipstick. Add more oil if necessary.

5. Final Checks

Start the engine: Let the engine run for a few minutes and check for leaks around the oil filter and drain plug.
Check oil level again: After the engine has run, turn it off, wait a few minutes, and check the oil level again, adding more oil if needed.
