When should an oil change be performed?

Performing an oil change based on the manufacturer’s recommendations or every 5,000 to 7,500 miles is essential for maintaining optimal engine performance and longevity. Manufacturers conduct extensive testing to determine the best oil change intervals for their vehicles, considering factors like engine design, oil formulation, and typical driving conditions. Following these guidelines helps to ensure that the oil maintains its lubricating properties, effectively removes contaminants, and protects engine components.

Routine oil changes prevent issues such as excessive engine wear, overheating, or complete engine failure, which can arise from using old or degraded oil. While some modern engines and synthetic oils may allow for longer intervals, adhering to this specific mileage range serves as a reliable rule of thumb to safeguard the vehicle's health.

Other options suggest criteria for changing oil that aren't as reliable; for instance, changing oil only when there are signs of wear relies on the assumption that symptoms will always be noticeable before serious damage occurs. Changing oil with the seasons doesn’t correlate with the actual condition of the oil or engine health. Establishing a routine based on manufacturer's recommendations or specified mileage is a proactive strategy that supports the vehicle's performance and durability over time.
