Changing your car’s engine oil regularly is crucial to maintain engine health, performance, and longevity. Generally, it is recommended to change engine oil every 10,000 to 15,000 kilometers or every 6 to 12 months under normal driving conditions. For diesel engines, oil changes may be needed more frequently, around every 8,000 to 10,000 kilometers. Factors like driving in heavy traffic, extreme weather, dusty or off-road conditions, and frequent short trips may require more frequent oil changes. Always consult your vehicle’s manual for the recommended oil type and change intervals. Regular oil changes ensure lubrication, reduce engine wear, remove debris, and help keep your engine running smoothly.
