Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical issues while working on the vehicle.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Oil Level

Remove the dipstick from the oil fill tube.
Wipe the dipstick clean, reinsert it, and then remove it again to check the oil level.
If the oil level is low, add the appropriate type of oil as specified in the owner’s manual.

3. Inspect for Leaks

Visually inspect the engine and undercarriage for any signs of oil leaks.
Use a flashlight to check around gaskets, seals, and the oil pan.
If leaks are found, identify the source and prepare for repairs or replacement of affected parts.

4. Replace Oil and Filter

Drain the old oil using an oil drain pan; remove the oil drain plug and allow oil to fully drain.
Replace the oil filter using an oil filter wrench; apply a small amount of new oil to the rubber gasket of the new filter before installation.
Reinstall the oil drain plug and torque to manufacturer specifications.
Fill the engine with the correct type and amount of new oil as specified in the owner’s manual.

5. Test Oil Pressure

Connect a mechanical oil pressure gauge to the oil pressure sender port.
Start the engine and observe the pressure reading; it should be within the manufacturer's specified range.
If the pressure is low, further investigation into the oil pump or potential blockages is required.
