It's advisable to consider both oil life and mileage when deciding when to change your vehicle's oil. Manufacturers' recommendations often suggest mileage intervals, but newer vehicles equipped with an oil-life monitoring system can provide a more accurate gauge based on how the car is driven. For optimal engine health, follow the soonest of either your car’s oil life system notification or the mileage interval. Regular oil changes are crucial for maintaining your vehicle's performance and longevity.
