The chemistry of the AMSOIL 100% Synthetic High Mileage Motor Oil is specifically designed for engines with more than 75,000 miles. It comes boosted with a detergent and dispersant additive package and anti-wear additives for ultimate protection for aging engines.

AMSOIL 100% Synthetic High-Mileage Motor Oil is more than an oil change. It is an investment long-term in a vehicle’s health. Purposefully built, this formula safeguards harshly at a rather very critical time in the life of a vehicle and may save dollars against pricey repairs while lengthening an engine’s serviceable life.

Key Benefits:

1. A Cleaner Engine!

The high-mileage formula of AMSOIL is extra detergent; it cleans out deposit buildup, adds life to dirty engines, and helps re-establish peak performance. Independent testing has shown that AMSOIL reduces sludge by an impressive 67%, evidence of its much-improved cleaning ability.

2. Durable Viscosity

As the engines age and wear, maintaining proper viscosity is very critical. This oil will continue to flow freely, maintaining its viscosity in extreme temperatures and running conditions, to provide dependable protection and performance.

3. Oil Consumption Control

High-mileage vehicles frequently have increased oil consumption. AMSOIL synthetic motor oil is extremely thermally stable over a broad temperature range, resisting volatility, and minimizes oil consumption.

4. Leak Protection

This oil contains seal conditioners that help restore the condition of old seals—thereby stopping existing leaks and preventing new ones—to help overcome a common problem found with higher-mileage engines.

5. API Licensed

This oil meets and often exceeds the requirements of API, which are common specifications found in most vehicle owner’s manuals.

6. Extended Protection

AMSOIL guarantees protection up to 12,000 miles or one year under normal service conditions. This will give you peace of mind and help reduce how many times you change your oil.
