Standard reference:
GB/T 38049-2019

Product overview:
PetroNexus Marine System Oil is blended from deeply solvent-refined base oils and an efficient multifunctional additive package. It meets the requirements of Chinese national standard GB/T 38049-2019 and is designed specifically for lubricating marine propulsion systems. It provides excellent detergency and dispersancy, oxidation and corrosion resistance, antiwear protection and water separation. It effectively protects the crankcases and hydraulic servo systems of low-speed marine crosshead two-stroke diesel engines, supporting stable long-term equipment operation. Its quality is at an advanced level among comparable domestic and international products.

Performance:
• Excellent thermal and oxidation stability withstands high temperatures, limits sludge formation and effectively extends lubricant service life.
• Good detergency and dispersancy keep engine internals clean and prevent components from sticking or seizing.
• Strong antiwear, rust-prevention and corrosion-protection properties protect critical components in marine propulsion systems.
• Excellent water separation and compatibility suit humid marine operating conditions and make topping up and maintenance convenient.

Applications:
• Grades 3005, 3008, 4005 and 4008 are all suitable for crankcase lubrication in low-speed marine crosshead two-stroke diesel engines.
• Grade 4008 is also suitable for trunk-piston diesel engines and marine auxiliary engines burning light fuel with a sulfur content below 0.5%, offering a broader range of applications.
• Widely used for circulating lubrication of key equipment in ocean-going and coastal vessels, including main-engine crankcases, auxiliary generator sets and gearboxes. It can also lubricate land-based diesel generator sets.

Packaging:
170 kg drums; 1-tonne IBC containers.
