Start with warming up your engine for 2 to 3 minutes once this is done turn off the engine.

Now you’re ready to get started:
1. Look under your car to find the drain plug. (The discharge screw or plug on the underside of the engine.)
2. Slide a container under the oil drain plug. (You want this container to catch the oil , so make sure it is large enough.)
3. Unscrew the oil drain plug.

4. Remove the cap from the oil filler hole on the top of your engine and unscrew the oil filter. The filter will have oil in it, so be careful not to spill when you remove it

5. Drain the oil from the filter into a collecting tray.
6. Open a new bottle of oil and dip a finger into it. Use the oil for wetting the seal on top of the new oil filter.
7. Screw the new filter into the engine where the old one was. Follow the instructions on the filter;
wipe around the place where the drain plug goes, perform this step only after all the oil drained.
8. Replace the oil drain plug and use an adjustable wrench to tighten.
9. Use a funnel to pour all but 1 liter of fresh oil into the filler hole.
10. Replace the oil filler cap and start the engine for 30 to 60 seconds. (be sure to check for leaks from the oil drain plug and the filter.)
11. Stop the engine and wait 5 to 10 minutes to allow the oil to settle in the oil pan , and then check the oil level again.
12. If required keep adding oil a little at a time. Check the stick after each addition, until you reach the full line on the dipstick.
13. Remove the drip pan under the car and give the car a test drive.
14. Allow the oil to settle for 5 to 10 minutes, then recheck the dipstick

That’s all there is to it, a few minutes work will save you a few dollars.
