Have you ever changed the car engine oil by yourself? If so, you are aware that it entails making various crucial technical decisions, like what kind of oil to use and how much to use. You must also adhere to certain directions for a successful oil change. Any error you make has the potential to harm the engine and reduce its lifespan. This article will discuss five common mistakes to avoid when changing engine oil. Why is it necessary to change the engine oil frequently? A car’s engine needs an oil change periodically, as the oil can wear off over time and lose its machine lubrication ability. Generally, the frequency of oil changes depends on several factors, such as the make and model of the car, the type of oil used, and the driver’s habits. In the past, it was recommended to change the oil every 3,000 miles or every three months, whichever came first. However, many modern cars can go for longer between oil changes. Most car manufacturers recommend an oil change after every 7,500 to 10,000 miles or every 6 to 12 months, whichever comes first. It’s important to check the owner’s manual of your specific car to determine the recommended oil change interval.
