How often should I change the oil in a car?

“Have your oil changed every 10,000 miles, 15,000 kilometers, or 12 months, whichever comes first. Such intervals should be reduced by half under severe driving conditions.”

You must have heard about the myth of the 4,500-kilometer (3,000-mile) oil change interval. Despite today’s remarkable advances in oil chemistry and engine technology, replacing oil every 4,500 kilometers (3,000 miles) is still considered necessary. In fact, most carmakers state in their service manuals the interval should be either 11,000 or 15,000 kilometers (7,500 or 10,000 miles). Then, why is such a myth still deemed applicable? Since customers are unfamiliar with the advances and progress occurring in the automotive industry, they continue to rely on this traditional rule. Instead, by choosing to follow the oil change interval recommended by most manufacturers, not only will you save time and money in maintenance costs, but you will also help protect the environment.
