Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the 12V battery to prevent electrical shorts.

2. Check and Top Off Engine Oil

Tools Required: Oil catch pan, funnel, new oil (refer to owner's manual for specifications).
Remove the oil fill cap and use a funnel to add oil if low.
Start the engine and run for a few minutes, then recheck the oil level and top off as needed.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set.
Locate the oil filter and use the oil filter wrench to remove it.
Apply a thin layer of new oil to the rubber gasket of the new oil filter, then install it by hand until snug.
Tighten it to the manufacturer's specification using a torque wrench.

4. Change Engine Oil

Tools Required: Socket set, oil catch pan, funnel.
Place the oil catch pan under the oil pan and remove the drain plug using a socket.
Allow the old oil to completely drain out.
Replace the drain plug and tighten to the specified torque.
Pour the new oil through the funnel into the oil fill cap.

5. Test Oil Pressure

Tools Required: External oil pressure gauge.
Remove the oil pressure sending unit and install the oil pressure gauge.
Start the vehicle and monitor the oil pressure reading.
If the pressure is still low, further investigation into the oil pump or engine internals may be necessary.
