Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool if it has been running.

2. Check and Top Off Oil Level

Tools Required: Oil dipstick, funnel, engine oil
Remove the dipstick, wipe it clean, reinsert it, and remove it again to check the oil level.
If the oil level is low, add the appropriate type of engine oil (refer to owner's manual for specifications).
Start the engine and let it run for a few minutes, then check the oil level again and add oil as necessary.

3. Inspect and Replace Oil Filter

Tools Required: Wrench set, oil filter wrench, oil catch pan
Identify the oil filter location and use an oil filter wrench to remove the old filter.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it hand-tight plus a quarter turn.

4. Replace Engine Oil

Tools Required: Socket set, oil catch pan, funnel
Remove the oil drain plug using a socket and let the old oil drain completely into the catch pan.
Replace the drain plug and tighten it to the manufacturer's torque specification (typically around 25 ft-lbs).
Pour the new engine oil into the engine through the funnel.

5. Test Oil Pressure

Tools Required: Oil pressure gauge
Remove the oil pressure sending unit and install the oil pressure gauge.
Start the engine and monitor the oil pressure reading; it should be within the manufacturer's specified range (usually 20-60 PSI at idle).
If pressure is low, further diagnostics may be needed on the oil pump or engine internals.
