It is prepared from deeply refined paraffin base mineral base oil and added to a selection of high-performance additives. This product includes 5040, 5050, 5070, 50100 and other brands of products. The 5070 ship used cylinder oil to pass 3,000 hours of solid ship tests on the "14 rounds of the China Sea". This product is suitable for cylinder lubrication of ship diesel engine with low speed cross fuel with different sulfur content.
Performance characteristics
L Excellent acid neutralization performance, effective neutralization of acid produced by poor fuel combustion
L Excellent abrasion resistance to extend the service life of engine components
L Good clean and dispersed performance to effectively prevent carbon accumulation at piston grooves and cylinder vents.
L Good diffusion performance, allowing the oil to reach the surface of the steel wall quickly, forming an oil film
