Oil lubricates every moving part in your car’s engine and is constantly filtered to keep it clean. As your engine parts move, so microscopic particles of metal get worn away and they are removed from the oil when they pass through the filtration system. Over time the oil filter becomes less effective and clogs up with the minute particles of metal. Eventually the oil can no longer be filtered and so the oil thickens and becomes less effective at lubricating your engine parts. If not replaced, your engine will be damaged, so it’s important that you regularly change your oil and replace the oil the filter in accordance with the time scales set by your car’s manufacturer.
If you were to ask any garage what the cause is of many engine failures, they will tell you that it’s because the oil and oil filter weren’t replaced often enough. If you have your car regularly serviced, then you know that every time the oil and filter will be replaced. However, if you don’t have your car regularly serviced then, even if you don’t do anything else, make sure you change the oil and filter regularly.
It’s a bit of a dirty job, but fairly easy if you have basic mechanical skills and a toolbox. It doesn’t take too long, although it may be necessary to jack up your car, so you can get under it to access the oil drain plug and possibly the oil filter.
Ensure you read through your car’s manual. It will tell you where the drain plug and oil filter are. It will also take you through the steps necessary to replace the oil and change the filter. Check out the type of oil the manufacturer recommends for your car; it’s important you use the correct type. Find out which oil filter you need. If it’s not listed in the manual, then you can find it on the side of the existing oil filter. Alternatively any car parts store will readily give you the correct filter, once you tell them your make and model. When you have the oil and filter nearby then remove the oil filler cap on the top of the engine. This will allow the oil to drain easier. It’s also best if your car’s engine is slightly warm; the engine is thinner and runs easier.
Put a tray under the oil drain plug and loosen the plug with a wrench. Remove the plug and let the oil drain. Remove the oil filter. Depending on how tightly it is fitted and how long it has been there you may be able to remove it by unscrewing it with your hands, otherwise you will need a large oil filter wrench.
Fill the new oil filter with as much oil as possible and then replace it and tighten. Replace the drain plug. Pout the new oil into the engine. Keep checking the oil dipstick to make sure you put in enough oil, but don’t overfill it. Replace the oil filler and you are done.
