Carrera GT Guide
Maintenance Schedule
Proper maintenance is essential for Carrera GT reliability and value preservation. This guide covers annual service, major intervals, fluid specifications, and costs based on our experience servicing dozens of CGTs.
Maintenance intervals based on real-world CGT service experience, not just factory recommendations.
Annual Service
Every Carrera GT should receive annual service regardless of mileage. Low-use cars are especially prone to issues from sitting—fluids degrade, seals dry out, and batteries fail.
| Service Item | Cost | Notes |
|---|---|---|
| Engine oil and filter change | $500-700 | 10W-60 synthetic, approx. 11 quarts |
| Brake fluid flush | $200-300 | DOT 4 racing specification |
| Air filter inspection/replacement | $150-400 | Replace every 2-3 years or as needed |
| Multi-point inspection | $300-500 | Fluid levels, hoses, belts, leaks, suspension |
| Tire rotation and inspection | $100-150 | Check for uneven wear, measure tread depth |
| Battery tender verification | Included | Critical for low-use vehicles |
Total Annual Service: $1,500-2,500

Storage & Low-Use Tips
Most Carrera GTs are driven less than 1,000 miles per year. Here's how to maintain them properly.
Do
- Keep on a quality battery tender at all times
- Store in climate-controlled space (40-70% humidity)
- Drive at least monthly to operating temperature
- Annual service even if barely driven
- Use fuel stabilizer for extended storage
Don't
- Let it sit on flat-spotted tires (use jacks for 3+ months)
- Store with parking brake engaged (drums can seize)
- Skip annual service because mileage is low
- Start without driving (condensation buildup)
- Store with old fuel (ethanol degrades quickly)
