How Often Should a Subaru Be Serviced?

Adhering to Subaru’s recommended service schedule is essential for maximizing your vehicle’s lifespan and maintaining warranty coverage. For Subaru owners in communities such as Crestwood, Maplewood, and Twin Oaks, staying on top of routine maintenance is particularly important given the region’s seasonal weather variations.

Subaru generally recommends servicing your vehicle every 6 months or 6,000 miles, whichever occurs first. This interval covers fundamental maintenance such as oil changes and tire rotations. More extensive inspections and replacements occur at longer intervals. Here’s a detailed look at the service timeline:

  • 6,000 Miles / 6 Months: Engine oil and filter change, tire rotation, and vehicle health check.
  • 12,000 Miles: Repeat the 6,000-mile service with additional inspections of brake lines, parking brake, disc pads, steering, and suspension.
  • 30,000 Miles: Brake fluid flush, air and fuel system inspections, cooling system check, and transmission fluid evaluation (manual models).
  • 60,000 & 120,000 Miles: In-depth inspections including wheel bearings, differential fluid exchanges, and timing belt replacement at approximately 90 months.
  • 90,000 Miles: Comprehensive vehicle inspection with computer diagnostics, brake system checks, and battery testing.

Driving habits and conditions impact how often these services should be performed. For example, frequent trips from Sappington to St. Charles on gravel roads may necessitate more frequent brake inspections or fuel filter changes. Always consult your owner’s manual or speak with our certified technicians to tailor the schedule to your specific Subaru model.

Is an Oil Change Included in the Service Plan?

Yes, oil changes are a fundamental component of Subaru’s service plans. Routine oil replacement is critical to preserving engine health by ensuring proper lubrication, cooling, and reduction of internal wear.

The standard oil change service under Subaru’s maintenance plan includes:

  • Replacement of engine oil with manufacturer-approved synthetic or conventional oil.
  • Installation of a new oil filter to trap contaminants and protect engine components.
  • Inspection and replacement of the oil drain plug gasket if needed to prevent leaks.
  • Basic visual check of other fluid levels and tire condition during your service visit.

While oil changes are included, it’s important to note that service plans typically do not cover wear-and-tear items such as brake pads or tires. These components require separate consideration and may be handled during regular inspections.

How Much Does Subaru Maintenance Cost?

Understanding the costs of Subaru maintenance helps drivers in communities like Oakland, Richmond Heights, and Ladue plan their budgets while ensuring their vehicles receive expert care.

Understanding Full Maintenance Plans vs. Service Plans

When considering your Subaru’s upkeep, distinguishing between a service plan and a full maintenance plan can help you make informed decisions.

  • Service Plan: Covers scheduled maintenance like oil changes, filter replacements, and inspections based on manufacturer intervals. It generally excludes wear-and-tear parts such as brake pads or tires.
  • Full Maintenance Plan: Often described as a more comprehensive option, it includes scheduled services plus coverage for wear-and-tear repairs and some mechanical failures. It typically encompasses labor costs and replacement of parts subject to regular degradation.

For Subaru owners in Webster Groves and Chesterfield, a full maintenance plan offers predictable budgeting and convenience, bundling various maintenance needs into one program. However, it comes at a higher cost and may require servicing exclusively at authorized dealerships like Sunset Hills Subaru.

Choosing the right plan depends on your driving habits, vehicle age, and personal preferences. Our service advisors are ready to help you explore options that best fit your lifestyle.
