AMSOIL 100% Synthetic High-Mileage Motor Oil

Engineered for vehicles with over 75,000 miles

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.

ENGINE CLEANLINESS

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

Engines can lose compression as cylinders and piston rings wear, leading to reduced horsepower. Maintaining a consistent 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

Oil consumption is often an issue in high-mileage vehicles. AMSOIL100% Synthetic High-Mileage Motor Oil is thermally stable across a wide range of temperatures, resisting volatility and consumption.

LEAK PROTECTION

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.

  • Fights deposits
  • Reduces oil consumption

Great For High Mileage

My vehicle reached 78,000 miles and it was time for an oil change. I wanted a motor oil that was DEXOS 1 Gen 3, high mileage type, and good for an extended oil change. Amol was the only one out there that met this criteria. It is good for 12,000 miles.
