The average age of vehicles in the U.S. has been on the rise for the past six years, hitting a new record of 12.5 years in 2023. The trend is being driven by vehicle prices that continue to skyrocket. As a result, many Americans are choosing to keep their vehicles longer.
AMSOIL 100% Synthetic High-Mileage Motor Oil is designed specifically for the unique demands of high-mileage engines, helping extend the life of vehicles with over 75,000 miles (120,000 km) on the odometer. It cleans and protects engines with boosted detergency and an additive package that fights oil breakdown and leaks.
Keeps engines clean
Deposits that have accumulated over time reduce engine performance and efficiency. AMSOIL High-Mileage Motor Oil provides enhanced detergency to breathe new life into dirty engines, removing deposit buildup to help restore peak performance.
Reduces engine wear
Horsepower loss can occur as engines lose compression from cylinder and piston-ring wear. Maintaining a consistent fluid film helps counteract compression loss by sealing combustion chambers.
AMSOIL High-Mileage Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Its highly durable viscosity provides proper film thickness, even in extreme operation.
Reduces oil consumption
AMSOIL High-Mileage Motor Oil is thermally stable across a wide range of temperatures to resist volatility and reduce oil consumption due to evaporation and combustion burn off caused by high temperatures.
Reduces oil leaks
Oil leaks are an inconvenience that can lead to lack of lubrication and potentially even engine failure.
AMSOIL High-Mileage Motor Oil provides a boosted dose of seal conditioners to restore aging seals and help stop leaks.
Extends engine life
AMSOIL 100% Synthetic High-Mileage Motor Oil provides an added boost of detergents to clean sludge and deposits. A robust viscosity helps maintain compression and provides additional wear protection, even after some wear has already occurred. Added seal conditioners extend the life of seals and help protect against drying, cracking and leaking.
These enhanced attributes are built right in to help keep your high-mileage vehicle on the road for the long haul.
