* Check online: Websites like the Chevrolet website (though finding a 25-year-old manual might be difficult), or sites selling automotive repair manuals (like Haynes or Chilton) may offer a digital version or at least a partial schedule. Search for "1998 Chevy Lumina owner's manual PDF".
* Check with a Chevrolet dealership: A local Chevy dealership *might* have access to older manuals or be able to give you some guidance based on the year and model.
* Use a general car maintenance guide: While not specific to your Lumina, general car maintenance guides (found in many auto parts stores or online) will provide schedules for common maintenance tasks (oil changes, filter replacements, etc.) Remember to check your owner's manual for specific recommendations *if* you find one, as these general guides are not always model-specific.
Keep in mind that the specific maintenance schedule will vary based on driving conditions and mileage. The owner's manual will have more detailed information on this.
