Solution

1. Preparation

Gather tools and materials: oil, oil filter, socket set, oil catch pan, funnel, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top Off Engine Oil

Sub-step 1: Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
Sub-step 2: If low, add the appropriate grade of oil through the oil filler cap using a funnel, monitoring the level with the dipstick.
Sub-step 3: After topping off, recheck the dipstick to ensure the oil level is within the recommended range.

3. Change the Engine Oil and Filter (if necessary)

Sub-step 1: Lift the vehicle using a jack and secure it with jack stands.
Sub-step 2: Place an oil catch pan under the oil pan, then remove the drain plug with a socket wrench to drain the old oil.
Sub-step 3: Replace the oil filter using an oil filter wrench, applying a small amount of new oil to the gasket of the new filter before installation.
Sub-step 4: Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 30-40 ft-lbs).
Sub-step 5: Refill the engine with new oil through the oil filler cap.

4. Check for Leaks

Sub-step 1: Start the engine and let it idle for a few minutes.
Sub-step 2: Inspect around the oil filter and drain plug for any leaks.
Sub-step 3: If no leaks are found, turn off the engine and recheck the oil level, adding more if necessary.
