Automobile engines have many moving parts. As these parts move and rub against each other, the force of friction creates heat. Oil lubricates the engine and absorbs heat, allowing the internal parts to work together effectively without overheating.
Over time, engine oil breaks down and wears out. When it does, it becomes less effective at lubricating the engine and absorbing heat. As an automobile owner, your goal is to change the oil in your engine before it breaks down and causes major engine troubles.
So how often should you change your oil? It depends on many factors, including the way you drive, how old your engine is, and where you live. Many mechanics will recommend you change your oil every 3,000 miles. Automobile manufacturers might suggest a longer interval, such as 5,000 miles. If you use special synthetic oil, you might be able to go 10,000 miles between oil changes!
For most people, an oil change every 5,000 miles would probably be just fine. You might want to consider changing your oil more often, though, if you tend to drive at high speeds, have an older engine or live in an area that is particularly hot, cold, or dusty.
Can you change the oil in your car by yourself? Yes, you can! But you will need a few special supplies to do so, including fresh oil, a new oil filter, an oil pan, an oil-filter wrench, a funnel, and maybe even ramps or a jack to elevate the car.
Changing the oil in an automobile isn’t a difficult process, but it does take time. It can also be a dirty job if you’re not careful with the oil. Some people choose instead to take their vehicle to a mechanic or an oil-change specialty business to have it done professionally.
