Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Disconnect the negative battery terminal for safety.

2. Check and Top-Up Engine Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert the dipstick and pull it out again to check the oil level.
3. If low, add the appropriate type of oil (consult owner's manual for specifications).
4. Start the engine and let it run for a minute, then check the oil level again and top off if necessary.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set, oil catch pan.
Sub-steps:
1. Place the oil catch pan beneath the oil filter.
2. Use the oil filter wrench to remove the old filter.
3. Apply a thin layer of new oil to the rubber O-ring of the new filter.
4. Install the new oil filter by hand until snug, then tighten slightly with the wrench.

4. Replace Engine Oil

Tools Required: Socket set, oil catch pan, funnel.
Sub-steps:
1. Place the oil catch pan under the oil pan's drain plug.
2. Remove the drain plug with a socket and let the old oil completely drain out.
3. Replace the drain plug and tighten to the manufacturer’s torque specification.
4. Pour in the new engine oil using a funnel.

5. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Sub-steps:
1. Remove the oil pressure sending unit.
2. Install the mechanical oil pressure gauge in its place.
3. Start the engine and observe the pressure reading; it should be within the manufacturer’s specified range.
4. If pressure is low, consider replacing the oil pump.
