Quick Answer
Warm up the engine, jack up the car and secure with stands, drain the old oil, replace the filter, reinstall the drain plug, add fresh oil to the correct level, then start the engine and check for leaks.
1

Prepare Your Vehicle

Watch: Prepare Your Vehicle

Start by running your engine for about 2 minutes to warm up the oil. Warm oil flows better and drains more completely. Engage your parking brake, and pop the hood. Then, Let the engine cool for a few minutes before you start working on it

Important Safety Note

Safety is critical here. Never work under a car that is only supported by a jack. Always use jack stands and make sure the vehicle is completely stable before sliding underneath

2

Lift and Secure the Car

Watch: Lift and Secure the Car

Use your car jack to lift the front of your vehicle. Place jack stands underneath the manufacturer's designated lift points and lower the car onto them. The front needs to be high enough for you to comfortably access the oil pan and filter. Double check that the car is stable before proceeding

3

Drain the Old Oil

Watch: Drain the Old Oil

Locate the oil drain plug on the bottom of the oil pan. It's usually a hexagonal bolt. Slide your drain pan underneath it and use your wrench to loosen the plug, then finish removing it by hand. As you remove the plug, be ready to move your hand out of the way quickly since warm oil will start flowing out immediately. Let it drain for 10 to 15 minutes for a complete drain

4

Replace the Oil Filter

Watch: Replace the Oil Filter

Now move the drain pan under the oil filter. It's usually a cylindrical component on the side of the engine. Unscrew the old filter by turning it counterclockwise. If it's stuck, use an oil filter wrench. Once removed, take your new filter and apply a small amount of fresh oil to the rubber gasket on the top. This ensures a proper seal. Screw the new filter on by hand until it contacts the mounting surface, then tighten it an additional quarter turn

Important Safety Note

Don't use a wrench to tighten the filter. You can crack the seal and cause leaks

5

Reinstall the Drain Plug

Watch: Reinstall the Drain Plug

Check that the drain plug's washer is in good condition. If it's damaged or worn, replace it with a new one. Reinstall the drain plug and tighten it to the manufacturer's specification. Be careful not to overtighten, as this can strip the threads in the oil pan

6

Add Fresh Oil

Watch: Add Fresh Oil

Remove the oil filler cap from the top of the engine. Insert a funnel to prevent spills. Double-check the correct oil type and amount. Pour in the new oil slowly, checking the level with the dipstick as you go. It's better to err on the side of too little since you can always add more. Once you've added the recommended amount, replace the cap

Important Safety Note

Overfilling the oil can cause pressure buildup and seal damage. Stay within the marked range on the dipstick

7

Start and Check for Leaks

Watch: Start and Check for Leaks

Start your engine and let it run for about a minute. Watch the oil pressure light; it should go out within a few seconds. Look underneath the car to make sure there are no leaks around the drain plug or filter. Turn off the engine, wait a minute, then check the dipstick again to confirm the level is correct. You're all set!

Important Safety Note

If the oil pressure light stays on or you see leaks, turn off the engine immediately and investigate

Frequently Asked Questions

How often should I change my oil?+

Most modern cars recommend changing oil every 5,000 to 7,500 miles. Check your owner's manual for the manufacturer's specific interval. If you do a lot of short trips, tow heavy loads, or drive in extreme temperatures, you might need to change it more frequently

What happens if I don't change my oil?+

Over time, oil breaks down and collects dirt and sludge. Dirty oil doesn't lubricate as well, leading to increased friction and heat. Eventually, this causes engine wear and can result in catastrophic engine failure. Regular oil changes are cheap insurance against expensive repairs

Can I use synthetic oil in my car?+

If your car came with synthetic oil from the factory, you can absolutely use synthetic. If it originally used conventional oil, you can switch to synthetic, but it's best to check with your mechanic first. Synthetic oil costs more but lasts longer and provides better protection

How do I know which oil weight to use?+

Your owner's manual will specify the correct oil weight, typically something like 5W-30 or 0W-20. You can also find this information on the oil filler cap under your hood. Always follow the manufacturer's recommendation for optimal engine performance
