100% Synthetic Diesel Oil SAE 5W-30

   100% Synthetic Diesel Oil SAE 5W-30

Outstanding Engine Protection

Camshaft wear can negatively affect valve timing, resulting in reduced horsepower and increased fuel consumption. AMSOIL 100% Synthetic Diesel Engine Oil forms a strong protective oil film on engine surfaces, while powerful anti-wear additives minimize metal-to-metal contact to extend engine life. Third-party testing shows this oil provides up to 6 times better wear protection than leading industry standards, helping extend engine life, lower maintenance costs, and reduce engine damage.

Excellent Viscosity Retention

Formulated with advanced 100% synthetic base oils, high-quality detergents, and dispersants, AMSOIL oil resists viscosity breakdown and keeps soot particles suspended to prevent the formation of large, abrasive deposits. Its low volatility helps maintain viscosity after high-temperature operation, offering enhanced engine protection and improved fuel economy.

Performance in Extreme Temperatures

This oil resists oxidation and thermal breakdown better than conventional diesel oils, helping keep engines cleaner and maintaining power and fuel efficiency. It also flows well at low temperatures, enabling faster oil circulation during startup and superior protection in cold conditions.

Reduced Oil Consumption

With a low evaporation rate, AMSOIL 100% Synthetic Diesel Engine Oil reduces oil consumption during operation and minimizes oil vapor entering the combustion chamber—making it safe for use with diesel exhaust after-treatment systems (e.g., DPF).

Applications

AMSOIL 100% Synthetic Diesel Engine Oil is designed for use in pickup trucks, vans, passenger cars, and SUVs requiring diesel engine oil meeting the following specifications:

• GM: dexosD, dexos2

• Chrysler: MS-11106

• Ford: WSS-M2C214-B1

• ACEA: C3

⚠️ Not recommended for engines requiring API CK-4, API SP, or older API specifications.

Compatibility with Other Oils

This oil is compatible with other synthetic and conventional engine oils that meet the same specifications. However, mixing may reduce performance and shorten the oil’s lifespan. AMSOIL does not guarantee extended service life if mixed with other oils. The use of aftermarket oil additives is also not recommended with AMSOIL synthetic engine oils.

Service Life

It is recommended to follow OEM or vehicle manual intervals when using AMSOIL 100% Synthetic Diesel Engine Oil. Extended drain intervals may be possible if supported by oil analysis.
