Despite today's significant advances in oil chemistry and engine technology, changing the oil every 4,500 kilometers (3,000 miles) is still necessary. In fact, most automakers state in their service manuals that the interval should be either 11,000 or 15,000 kilometers (7,500 or 10,000 miles). So why does this myth still apply? Because customers are unaware of the developments and advancements taking place in the automotive industry, they continue to rely on this traditional rule of thumb. Instead, by choosing to follow the oil change interval recommended by most manufacturers, you will not only save time and money on maintenance costs, but you will also help protect the environment.
