Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Allow the engine to cool down if it has been running.

2. Check Oil Level

Open the hood and remove the dipstick.
Wipe it clean, reinsert it, and remove it again to check the oil level.
If low, top off with the recommended oil type.

3. Inspect for Leaks

Visually inspect the oil pan, gaskets, and seals for any signs of leakage.
Clean any oil residue with a degreaser to help identify new leaks after the engine runs.

4. Change Oil and Filter

If the oil is dirty or old, drain the old oil using a socket set to remove the oil drain plug.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug and torque to manufacturer specifications (typically around 25 Nm).
Fill the engine with new oil, adhering to the manufacturer’s recommended oil type and capacity (usually 5W-30 or 0W-40).

5. Test Oil Pressure

Remove the oil pressure sending unit using a socket set.
Install an oil pressure gauge in its place and start the engine.
Check the reading; it should be within the specified range (typically 1.5 to 3.0 bar at idle).
If the pressure is low, further diagnosis may be required, such as checking the oil pump.
