Solution

1. Preparation

Gather tools and parts: mechanic's gloves, oil filter wrench, socket set, mechanical oil pressure gauge, new oil, and oil filter if needed.
Ensure the vehicle is on a level surface and the engine is cool.

2. Check and Top Off Oil Level

Remove the dipstick, clean it with a cloth, reinsert it, and remove it again to check the oil level.
If low, add the appropriate type and grade of oil as specified in the owner's manual.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set.
Use the oil filter wrench to remove the old oil filter.
Before installing the new filter, apply a small amount of new oil to the rubber gasket.
Install the new oil filter hand-tight, then tighten slightly more with the wrench.

4. Change Engine Oil

Tools Required: Socket set, oil pan, funnel.
Remove the oil drain plug using a socket set and allow the old oil to drain completely into an oil pan.
Replace the drain plug and tighten it to the manufacturer's torque specifications.
Use a funnel to pour in the new oil through the oil filler cap, ensuring to use the correct type and amount.

5. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Remove the oil pressure sending unit and install the mechanical gauge.
Start the engine and observe the pressure reading. It should be within the manufacturer's specified range.
If the pressure is still low, further inspection of the oil pump and its components may be necessary.
