Check Your Number, Because 3,000 Miles May Be Too Early to Change Your Oil

Needing to change your car's oil every 3,000 miles no longer applies to most cars. Many cars today can go longer without affecting engine wear. Automakers are regularly recommending oil changes at 5,000, 7,000 or even 10,000 miles based on driving conditions. Check your vehicle's user manual for guidelines on when to change your oil.
