HD50 engine oil is a monograde, high-viscosity lubricant formulated for use in both gasoline and diesel engines, particularly those operating under high load and temperature conditions. It conforms to the API SP specification for modern gasoline engines and the API CD specification for older diesel engines, making it a dual-purpose oil suitable for mixed fleet use where both engine types are present.
🔧 Key Features and Benefits:
-
High Viscosity (SAE 50):
Offers excellent film strength, particularly in high-temperature environments such as heavy-duty trucks, construction equipment, or older performance vehicles. Helps maintain oil pressure and protect engine components under stress. -
API SP Performance (Gasoline Engines):
Ensures protection against low-speed pre-ignition (LSPI), sludge formation, and wear in gasoline engines. Also supports turbocharger cleanliness and timing chain wear protection in modern engines. -
API CD Performance (Diesel Engines):
Provides sufficient protection for older diesel engines without after-treatment systems. Offers soot dispersion and acid neutralization capability, minimizing piston deposits and wear. -
Detergent and Dispersant Additives:
Keeps engine internals clean by suspending contaminants and reducing deposit formation. -
Zinc-Based Anti-Wear (ZDDP):
Contains zinc dialkyldithiophosphate, an effective anti-wear additive, especially beneficial in engines with flat tappet camshafts. -
Thermal and Oxidation Stability:
Maintains lubricating properties under extended high-temperature operation, preventing oil thickening and degradation. -
Corrosion and Rust Protection:
Inhibits oxidation and guards metal surfaces during storage or intermittent use.
🏁 Applications:
-
Suitable for heavy-duty, naturally aspirated or turbocharged diesel engines.
-
Ideal for older gasoline engines requiring high-viscosity oils, especially in hot climates.
-
Not recommended for modern engines requiring low-viscosity oils or those with DPF, EGR, or SCR systems due to higher ash content.
