Solution

1. Preparation

Gather all necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is turned off for at least 15 minutes.
Wear protective gloves and safety glasses.

2. Inspect Oil Level

Sub-step 1: Open the hood and locate the dipstick.
Sub-step 2: Pull the dipstick out and wipe it clean with a lint-free cloth.
Sub-step 3: Reinsert the dipstick fully and remove it again to check the oil level.
Sub-step 4: Ensure the oil level is between the minimum and maximum marks. If low, it indicates a need for an oil change.

3. Assess Oil Condition

Sub-step 1: Observe the oil color; new oil is typically amber, while old oil appears dark and dirty.
Sub-step 2: Rub a small amount of oil between your fingers to feel its viscosity; it should be smooth, not gritty.
Sub-step 3: If the oil appears thick or has particles, it is time for an oil change.

4. Check for Oil Leaks

Sub-step 1: Look for any visible oil spots or puddles under the vehicle.
Sub-step 2: Inspect the oil filter and drain plug for signs of leakage.

5. Monitor Oil Change Light

Sub-step 1: Start the engine and observe the dashboard for the oil change light.
Sub-step 2: If the light remains illuminated after starting, schedule an oil change promptly.
