117 views

Waiting a year between oil changes can be bad for your vehicle, especially if you drive frequently or in challenging conditions. Most manufacturers recommend oil changes every 5,000 to 7,500 miles. However, modern synthetic oils and some new car models may safely extend that period up to 10,000 miles or one year, whichever comes first. Always check your car's manual for specific guidance, as neglecting timely oil changes can lead to engine damage, reduced efficiency, and potential costly repairs.

FAQs & Answers

  1. How often should I really change my car's oil? Most manufacturers recommend oil changes every 5,000 to 7,500 miles, though some modern synthetic oils allow extensions up to 10,000 miles or one year.
  2. Can I wait a year between oil changes if I don’t drive much? Even if you drive less, oil degrades over time, so it’s generally advised not to exceed one year between oil changes regardless of mileage.
