      What is saved, and what is not

      • Saved cards live in this browser's local storage. There is no account, VIN lookup, server backup, email reminder, or cross-device sync.
      • Keep grade and specification as separate fields. A saved 5W-30 note is incomplete if the manual also requires dexos, ACEA, API/ILSAC, or another OEM approval.
      • Treat dates and mileage as planning notes. The real interval still comes from the owner manual, maintenance minder, and service conditions.
