Solution

1. Preparation

Gather tools and parts: oil pressure gauge, socket set, oil filter wrench, new oil, new oil filter.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Add Engine Oil

Remove the dipstick, clean it, and reinsert it to check the oil level.
If the oil level is low, add the recommended oil type (refer to owner's manual) until it reaches the correct level.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, tightening it by hand until snug, then an additional 3/4 turn.

4. Change Engine Oil

Place a drain pan under the oil pan and remove the drain plug with a socket set.
Allow the old oil to fully drain out.
Reinstall the drain plug and torque it to the manufacturer's specifications (typically around 30 lb-ft).
Add new engine oil through the oil filler cap according to the recommended quantity in the owner's manual.

5. Test Oil Pressure

Install the oil pressure gauge in place of the oil pressure sending unit.
Start the engine and observe the oil pressure readings. They should be within the normal range (typically 20-60 psi at idle).
If pressure is still low, the oil pump may need to be replaced.
