- Cool down after high-performance driving
- Address minor issues before they become major problems
- Clean your engine bay periodically to spot leaks early
- Check your oil level regularly between changes (WRXs can consume oil)
10-Year Cost of WRX Maintenance
According to industry data, the average 10-year maintenance cost for a Subaru WRX is approximately $6,679, which is about $914 above the industry average. This reflects the performance-oriented nature of the vehicle and its more demanding maintenance requirements.
By following the proper service schedule and considering some DIY maintenance, you can potentially save 40-50% on these long-term costs while keeping your WRX in optimal condition.
The Importance of OEM vs. Aftermarket Parts
When servicing your WRX, part selection matters:
- OEM (Original Equipment Manufacturer): These Subaru parts match exactly what came on your car. They typically cost more but ensure compatibility and quality.
- Aftermarket: These non-Subaru parts vary widely in quality and price. High-quality aftermarket parts can sometimes outperform OEM, while budget options may compromise reliability.
For critical components like timing components, engine internals, and electronics, OEM parts are often worth the premium. For items like filters, brake pads, and fluids, high-quality aftermarket options can save money without sacrificing performance.
Choosing the Right Oil for Your WRX
Oil selection is particularly important for turbocharged engines:
- Factory recommended: 0W-20 synthetic for normal driving
- Performance driving: 5W-30 full synthetic with high temperature resistance
- Track use: Consider specialized racing oils with highest temperature protection
Don’t skimp on oil quality – the extra $20-30 for premium synthetic oil is cheap insurance for your engine’s health, particularly when pushing the car’s performance limits.
Special Considerations for Modified WRXs
If you’ve modified your WRX with performance parts, adjust your maintenance schedule accordingly:
- Aftermarket ECU tunes typically require higher octane fuel
- More powerful setups need more frequent oil changes
- Upgraded turbo systems may require different oil weights
- Performance brakes often need different pad materials
- Lowered suspensions require more frequent alignment checks
Always consult with your tuner or performance shop about maintenance adjustments needed for your specific modifications.
Remember, maintaining your Subaru WRX properly not only ensures peak performance but also protects your investment and helps maintain its value over time. Whether you choose dealer service, independent shops, or DIY maintenance, the key is consistency and quality.
