You'll need the correct type and amount of engine oil, a new oil filter, a wrench set (including a socket for the drain plug and an oil filter wrench), a funnel, a drain pan, and jack stands with a floor jack for safe access. For most people, the most critical step is consulting the owner's manual to get the exact oil specifications and capacity right.
The process involves safely raising the vehicle, draining the old oil, replacing the filter, adding new oil, and checking for leaks. While it's a straightforward task for a DIYer, getting any step wrong can lead to expensive engine damage. If you're not comfortable working under a raised car or disposing of the used oil properly, having a professional handle it is a wise and safe choice.
Here’s a quick checklist of the essentials:
| Item | Purpose & Key Details |
|---|
| Engine Oil | Check your owner's manual for the correct viscosity (e.g., 5W-30) and type (conventional, synthetic blend, or full synthetic). The average car takes 4-6 quarts. |
| Oil Filter | A new filter is mandatory. It traps contaminants and has a critical sealing gasket. Get one specifically for your car's make, model, and engine. |
| Drain Pan | A container with at least a 6-quart capacity to catch the old, hot oil. |
| Wrench/Socket Set | Needed to remove the drain plug. The size is often 13-19mm. A ratchet makes this easier. |
| Oil Filter Wrench | Essential for loosening the old filter, which is often on too tight to remove by hand. |
| Funnel | Prevents spills when pouring new oil into the engine. |
| Jack & Jack Stands | Never work under a car supported only by a jack. Jack stands are non-negotiable for safety. |
| Shop Rags/Gloves | For cleaning up spills and protecting your hands from hot oil. |
Before you start, run the engine for a minute to warm the oil (it drains faster) but be careful—components will be hot. Locate the drain plug and oil filter underneath the car. Place the drain pan under the plug, loosen the plug with the wrench, and remove it by hand (wear gloves). Once drained, reinstall the drain plug and tighten it securely—overtightening can strip the threads.
Use the oil filter wrench to remove the old filter. Wipe the filter mounting surface clean, apply a thin film of new oil to the gasket of the new filter, and screw it on by hand until the gasket contacts the base, then tighten it another 3/4 turn. Lower the car, use the funnel to add the new oil, and start the engine. Check for leaks around the drain plug and filter. Finally, check the oil level with the dipstick and top off if necessary.
