Product Description
With rapidly rising new-vehicle pricing and the high cost of repairs, drivers are keeping their vehicles on the road longer than ever. Preventive maintenance that includes high-quality lubricants is key for keeping vehicles safe and dependable for the long haul. AMSOIL 100% Synthetic High-Mileage Motor Oil is designed specifically for the unique demands of high-mileage engines, helping extend the life of your vehicle. It delivers purpose-built protection at a time in your vehicle’s life where it could benefit from more-robust maintenance. It cleans and protects engines with boosted detergency and an additive package that fights oil breakdown and oil leaks.

• Fights deposits
• Reduces oil consumption
• Helps prevent leaks

ENGINE CLEANLINESS
• Enhanced detergency to breathe new life into dirty engines.
• Removes deposit buildup to help restore peak performance.

Deposits reduce engine performance and efficiency. AMSOIL 100% Synthetic High-Mileage Motor Oil provides enhanced detergency to breathe new life into dirty engines by removing deposit buildup to help restore peak performance.

DURABLE VISCOSITY
• Maintains proper film thickness in extreme operation.

Engines can lose compression as cylinders and piston rings wear, leading to reduced horsepower. Maintaining a consisting fluid film helps to counteract compression loss by sealing combustion chambers to maintain performance. AMSOIL 100% Synthetic High-Mileage Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Its highly durable viscosity provides proper film thickness, even during extreme operation.

OIL-CONSUMPTION CONTROL
• Thermally stable across a wide range of temperatures.
• Resists volatility and oil consumption.

Oil consumption is often an issue in high-mileage vehicles. AMSOIL 100% Synthetic High-Mileage Motor Oil is thermally stable across a wide range of temperatures, resisting volatility and consumption.

LEAK PROTECTION
• Conditions seals to help prevent leaks.

Oil leaks are an inconvenience and if left unchecked can lead to lack of lubrication and engine failure. AMSOIL 100% Synthetic High-Mileage Motor Oil provides a boosted dose of seal conditioners to restore aging seals and help stop leaks.

API LICENSED

Licensed by the American Petroleum Institute (API) to meet and exceed requirements commonly found in owner’s manuals.

SERVICE LIFE
Normal Service: Up to 12,000 miles (19,200 kms) or one year, whichever comes first, in personal vehicles not operating under severe service.
