For a diesel Jetta, it's generally recommended to change the oil every 10,000 to 15,000 miles, depending on driving conditions and the type of oil used. Always consult the owner’s manual for specific guidance, as some models may have different requirements. Additionally, consider changing the oil more frequently if you drive in severe conditions, such as extreme temperatures or heavy towing. Regular oil changes help maintain engine performance and longevity.
