How To Do It:
Run your car until the engine is totally warmed. Park on the level. To unscrew the sump plug you may have to jack-up the vehicle. With some models you can simply crawl underneath. (Make sure the car is secure before you get underneath it.)
Unscew the oil filler cap on top of the engine. This helps the oil come out better.
Unscrew the oil sump plug under the engine and let the hot old oil flow into your container. Be careful you don't get burnt.
Leave the oil to drain for a while.
Meanwhile unscrew the old oil filter and fit the new one.
Now screw back the oil sump plug securely. Pour the new oil in through the oil filler and screw back the oil filler cap. Be careful to put the right amount of oil in. Do not overfill.
Clear away your tools and the old oil and start the engine. Let it run for a few minutes and check for leaks at the oil filter and oil sump plug.
...Now, if this is your wife's/girlfriend's car, after you finish go inside shower, and stretch really well because most likely homegirl is ABOUT TO PUT IT ON YOU!!!!
