TRIAX Synergy SRT 10W-40 Synthetic High Mileage Motor Oil is engineered to provide older engines with the extra protection they need, helping to restore smooth operation and extend engine life well beyond 75,000 miles. Its advanced synthetic formula reduces engine noise and vibration, minimizes blow-by, and helps control smoke by reducing oil burn-off and maintaining cleaner combustion. Seal conditioners rejuvenate aging seals to reduce leaks and oil consumption, while high detergency chemistry protects against harmful deposits and sludge that can rob engines of power. With outstanding thermal stability and resistance to breakdown under high temperatures, this oil keeps high-mileage cars, SUVs, and trucks running cleaner, quieter, and more reliably, mile after mile. 

• Engineered for High Mileage Protection: Specially formulated for vehicles over 75,000 miles, this oil contains seal conditioners to reduce leaks and consumption while helping eliminate oil burning, noise, and smoke, and restoring power and torque
• Seal Conditioning: Specialized seal conditioners help rehydrate and maintain elasticity in older seals, helping to prevent oil leaks and consumption
• Superior Wear Control: Advanced anti-wear additives, synthetic base oils, and proprietary technology deliver exceptional protection against friction and wear, even under severe driving conditions, making it ideal for high-mileage engines
• Enhanced Oxidation Stability: Resists oil breakdown at high temperatures, keeping engines cleaner and extending oil life for longer service intervals
• Strong Deposit & Sludge Defense: A high-detergency formulation protects against sludge, varnish, and other harmful deposits that reduce performance and efficiency while rapidly dissolving deposits from pistons, cams, bearings, turbochargers, and other critical components
• Wide Compatibility: Ideal for gasoline engines requiring 10W-40 viscosity, including turbocharged and naturally aspirated engines in cars, SUVs, and light trucks
