You pour oil into your car’s engine through the oil filler cap, which is located on top of the engine. It’s typically a black or yellow twist-off cap with an oil can symbol on it. Before adding oil, make sure the car is parked on a level surface and the engine is cool to the touch.
The most common mistake is confusing the oil filler cap with other caps under the hood, like the one for brake fluid or coolant. To find it, pop open the hood and look for a cap labeled “Engine Oil” or bearing the oil can icon. It’s usually on a valve cover—a metal or plastic piece sitting on top of the engine block. If you're unsure, your vehicle's owner's manual has a diagram that pinpoints its exact location.
Once you’ve found the correct cap, clean the area around it with a rag to prevent dirt from falling into the engine. Remove the cap and use a funnel to pour in the correct type and amount of oil specified for your car. Overfilling can be just as harmful as having too little oil.
| Step | Action | Key Tip |
|---|
| 1 | Park on a level surface & ensure engine is cool. | Prevents inaccurate oil level reading. |
| 2 | Locate the oil filler cap under the hood. | Look for the oil can symbol. |
| 3 | Consult the owner's manual for oil type and capacity. | Using the wrong oil can damage the engine. |
| 4 | Clean the area and use a funnel. | Keeps contaminants out of the engine. |
| 5 | Add oil slowly, checking the dipstick frequently. | Avoid overfilling. |
After adding oil, use the dipstick to check the level. It should be between the "MIN" and "MAX" marks. Reinstall the cap securely and you're done.
