Changing your vehicle's oil typically every 3,000 to 5,000 miles is a widely accepted maintenance practice that helps ensure your engine runs smoothly and efficiently. Regular oil changes help remove dirt, contaminants, and debris that accumulate in the oil, which can ensure better lubrication of the engine parts and improve its overall performance and lifespan.

Referring to your owner's manual is essential because it provides the manufacturer's recommendations specific to your vehicle, which may have varying requirements based on factors such as engine type, oil type (conventional vs. synthetic), and driving conditions. Following these guidelines ensures optimal engine health.

Intervals that are too short, like changing oil every 1,000 miles, may lead to unnecessary costs and waste without substantial benefits, while waiting until every 10,000 miles may risk damage if the oil gets too dirty or breaks down. Additionally, relying solely on indicators that show engine trouble could lead to significant engine problems before issues are noticed, making regular maintenance essential.
