Data sources

Sources

MaintenanceSpec builds schedules only from manufacturer-published documentation.

Accepted source types

  • Manufacturer warranty and maintenance guides
  • Manufacturer owner's manuals
  • Official manufacturer service documentation, where appropriate and accessible

What is not used as a primary source

  • Blogs and forum posts
  • Generic third-party maintenance charts
  • Unsourced or AI-generated maintenance information

These may describe general concepts correctly, but they are not treated as an authoritative source for a specific vehicle's schedule.

Source records by vehicle

Each published model page links to the specific source document and page range its schedule was built from. See a vehicle's own maintenance schedule page for its source records.
