Scheduled maintenance is a timeline of service tasks-oil changes, filter replacements, fluid checks, belt inspections-designed to keep your Subaru reliable and safe. Your owner's manual lists these intervals based on miles and months.

Following the schedule helps prevent breakdowns, extends engine life, maintains fuel efficiency, and often protects your warranty. Skipping steps can lead to costly repairs down the road and may affect warranty coverage.

Every Subaru model has its own schedule. Castle Subaru McHenry's Service Department knows Subaru maintenance inside and out and can walk you through what's due. Call (779) 601-0797, and we'll keep your service records organized and up to date.
