Regularly checking your engine oil is one of the easiest and most effective ways to maintain your car’s health. Proper oil levels help your engine run smoothly, prevent overheating, and extend the life of your vehicle. Whether you’re a new driver or simply brushing up on basic car maintenance, this guide will walk you through everything you need to know.
Why Checking Engine Oil Matters
Engine oil lubricates moving parts, reduces friction, removes heat, and helps keep your engine clean. Driving with low or dirty oil can result in:
- Poor engine performance
- Increased fuel consumption
- Costly engine damage
Checking your oil regularly—ideally once a month—can prevent these issues.
What You Need
- A clean rag or paper towel
- Gloves (optional)
- Your vehicle owner’s manual
How to Check Engine Oil Step-by-Step
1. Park on a Level Surface
Ensure your car is parked on flat ground. This helps you get an accurate reading.
2. Turn Off the Engine and Let It Cool
Turn off the engine and wait about 5–10 minutes. Oil needs time to settle back into the pan.
3. Open the Hood
Pull the hood-release lever inside your car, then open the hood and secure it with the prop rod.
4. Locate the Dipstick
Look for a colored handle (usually yellow or orange). The dipstick is typically labeled “Engine Oil.”
5. Pull Out the Dipstick
Remove it carefully and wipe the oil off the end with a clean cloth or paper towel.
6. Reinsert and Remove Again
Slide it all the way back in, then pull it out once more to check the level.
7. Read the Oil Level
You will see markings such as:
- MIN / MAX
- L / H
- Two small holes or lines
Your oil should be between these marks. If it’s below the minimum, it’s time to add oil.
8. Check Oil Color and Consistency
Healthy oil should be:
- Amber or light brown
- Smooth and free of debris
Dark, gritty, or thick oil means it’s time for a change.
9. Add Oil if Needed
Consult your owner’s manual for the correct oil type (e.g., 5W-30 or 0W-20). Add a small amount at a time, rechecking the dipstick to avoid overfilling.
10. Close the Hood Securely
Ensure everything is properly closed before driving.
How Often Should You Check Engine Oil?
Most experts recommend checking once a month or before long road trips. If your car is older, leaking, or burning oil, check it more frequently.
