Solution

1. Preparation

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

2. Check and Add Oil

Sub-step 1: Remove the oil filler cap located on the engine valve cover.
Sub-step 2: Use a funnel to add the appropriate type and amount of oil as specified in the owner’s manual.
Sub-step 3: Reinstall the oil filler cap securely.

3. Replace Oil Filter

Sub-step 1: Position the oil catch pan under the oil filter.
Sub-step 2: Use an oil filter wrench to remove the old oil filter.
Sub-step 3: Apply a little new oil to the rubber gasket on the new oil filter, then install the new filter by hand until snug.
Sub-step 4: Tighten the oil filter according to the manufacturer's specifications (usually about 3/4 turn after the gasket makes contact).

4. Change Engine Oil

Sub-step 1: Remove the oil drain plug using a socket wrench and allow the old oil to completely drain into the catch pan.
Sub-step 2: Clean the drain plug and reinstall it, tightening it to the manufacturer's torque specifications.
Sub-step 3: Pour in the new oil through the oil filler cap, using the type recommended in the owner’s manual.

5. Test Oil Pressure

Sub-step 1: Install the mechanical oil pressure gauge in the oil pressure sending unit location.
Sub-step 2: Start the engine and observe the oil pressure reading. It should be within the manufacturer's specified range.
Sub-step 3: If the pressure is low, consider replacing the oil pump or further diagnosing the oil system.
