  • A privately owned passenger car or light commercial vehicle


  • 18,000 miles or 12 months after oil change, whichever comes first

  • This warranty takes effect 30 days or 1,000 miles from the engine oil change date, whichever is later, provided a valid registration is in place. A claim is only valid if all criteria are met, which are outlined in the terms and conditions.
