Changing your own oil, step by step: the tools, draining the old oil, the new filter, filling and checking, and disposing of the old oil.
Changing your car's oil is one of the best things you can do to keep it running smoothly, and with a little practice it is a job you can do at home. This guide walks you through it.
1. Gather the tools and materials
- New oil: your owner's manual gives the type and quantity.
- A new oil filter: replace it at every oil change.
- A socket or box wrench for the drain plug.
- An oil filter wrench.
- A funnel.
- A drain pan for the old oil.
- Gloves and rags.
Having everything at hand keeps the job clean and smooth.
2. Park safely and let the engine cool
Park on flat, level ground with the engine off. If you have been driving, let the engine cool for at least 10 to 15 minutes, so you don't get burned and the oil settles in the pan.
3. Find the drain plug
Raise the car on ramps or jack stands; never work under a car held up only by a jack. The drain plug is usually on the bottom of the oil pan. Put the drain pan underneath it.
4. Drain the old oil
Loosen and remove the drain plug and let the oil drain completely, which takes a few minutes. Clean the plug and its threads, then put it back and tighten it securely.
5. Remove the old filter
Move the drain pan under the filter, since a little oil will spill. Unscrew the filter with the filter wrench, carefully, as it is still full of oil. Wipe the filter mount clean.
6. Fit the new filter
Spread a thin film of new oil on the new filter's rubber gasket: it seals better and comes off more easily next time. Screw the filter on by hand until snug, without over-tightening.
7. Add the new oil
Remove the oil fill cap on top of the engine, put the funnel in and pour in the new oil. Use the amount your manual gives: overfilling can harm the engine.
8. Check the level
Put the fill cap back and run the engine briefly to circulate the oil. Turn it off, wait a moment and check the dipstick. Add a little more if needed.
9. Dispose of the old oil properly
Pour the old oil into a sealed container, and take it with the old filter to an authorized collection point: many auto shops and recycling sites accept used oil.
Why regular oil changes matter
Oil collects dirt and debris and protects the engine less over time. Regular changes keep the engine clean and lubricated, improve fuel economy and help avoid costly repairs.

- Use the oil your owner's manual recommends.
