⚠️ UPDATED SERVICE INTERVAL & TECHNICAL ADVICE
Maintain Your Drivetrain: Gear oil degrades over time due to heat and shear forces, leading to notched shifting or differential whine. Proactive maintenance ensures your drivetrain remains quiet and efficient.
Recommended Intervals:
- Optimal Performance: Replace every 30,000 – 50,000 miles.
- Heavy Duty/Track Use: Inspect every 15,000 miles or after extreme heat cycles.
