Changing your car oil is one of the simplest yet most vital maintenance tasks every car owner should know. The engine oil lubricates, cleans, and protects the engine’s internal components, ensuring a long and trouble-free life for your car. Even if you drive one of the cars with the best safety ratings, skipping oil changes can affect its performance and durability.
In this guide, you’ll learn how to change car oil effectively, why it’s important, and the tools you’ll need for the job.
Why Changing Car Oil Is Important
Oil plays a vital role in:
-
Lubrication – Reducing friction between engine parts.
-
Cooling – Helping to dissipate heat.
-
Cleaning – Removing sludge, dirt, and debris.
-
Protecting – Preventing rust and corrosion.
Without regular oil changes, your engine can overheat, lose efficiency, and eventually fail. Most car manufacturers recommend an oil change every 3,000 to 7,500 miles, depending on your car’s make and model.
Tools and Materials You Will Need
Here’s what you’ll need to get started:
| Tool/Material | Purpose |
|---|---|
| New Oil | The right oil for your car (check owner’s manual). |
| New Oil Filter | Always replace the oil filter when changing oil. |
| Wrench Set | To remove the drain plug and filter. |
| Oil Pan | To catch old oil. |
| Funnel | To pour new oil. |
| Jack and Jack Stands | To lift and secure the car. |
| Gloves and Rags | To keep hands clean and wipe spills. |

10 Simple Steps to Change Your Car Oil
1. Prepare Your Car
Park your car on a flat surface. Let the engine cool down for a few minutes if it’s been running.
2. Lift the Car
Use a jack and jack stands to raise the car. Never crawl under a car that isn’t securely lifted.
3. Remove the Oil Cap
Open the car’s hood and remove the oil cap. This allows air to flow and helps oil drain smoothly.
4. Position the Oil Pan
Place an oil pan under the drain plug.
5. Remove the Drain Plug
Use a wrench to remove the drain plug. Let the old oil drain completely (this can take a few minutes).
6. Replace the Oil Filter
Remove the old oil filter using a filter wrench. Lubricate the rubber gasket of the new filter with a little oil, then install it by hand until snug.
7. Reinstall the Drain Plug
Replace the drain plug and tighten it securely (don’t overtighten).
8. Add New Oil
Check your owner’s manual for the correct oil quantity and type. Use a funnel to pour in the oil.
9. Check the Oil Level
Wait a moment for the oil to settle, then use the dipstick to confirm it’s at the right level.
10. Run the Engine
Start the engine and let it run for a minute, then turn it off. Check the oil level one more time and top it up if needed.
