Proper car maintenance starts with changing engine oil regularly. Engine oil is designed to lubricate the moving parts inside the car and reduce friction. Engine oil also prevents the engine from being damaged by oil and soot.
Many people end up having problems with their cars because they don’t realize when it’s time to take the car for an oil change. Most drivers rely on professionals to tell them when when the oil needs a change. It’s important for drivers to be on the lookout for problems caused by old oil in the car. Not changing oil often enough will eventually cause the car to break down. That’s why you should be on the lookout for any serious problem that could’ve been caused by old oil.
