3 main kinds of marine lubricants: system marine engine oil, medium speed trunk piston engine oil, and marine cylinder engine oil
  Marine cylinder engine oil: Features and benefits: 1) Superior acid neutralization ability 2) Excellent wetting property 3) Excellent detergency and dispersancy to effectively handle deposits in piston grooves 4) Perfect anti-wear to ensure liner wear protection 5) Outstanding oxidation stability to control the oxidation derivatives effectively 6) Superior storage stability 7) Good seal ability to prevent fuels from leaking Recommended applications: 1) Suitable for crosshead engines burning high sulfur content diesel or residual fuels 2) C***0 is suitable for low speed, two-stroke, crosshead and supercharge engines burning fuels with sulfur content less than 2.5% by weight 3) C***0 and C***0 are suitable for engines burning fuels with sulfur content less than 3.0% and 4.0% by weight respectively System marine engine oil: Features and benefits: 1) Perfect anti-emulsification and water separation properties 2) Outstanding oxidation stability to ensure long drain interval 3) Excellent detergency and dispersancy properties to assure the cleanness of crankcase and other parts 4) Good antirust and anticorrosion ability 5) Better alkalescence to neutralize acid substances formed during the burning of fuel Recommended applications: 1) Suitable for the lubrication of crankcase of low speed crosshead engines 2) S***2 and S***2 can also be used as middle speed engine oil working in diesel trunk piston engines with the fuel containing sulfur lower than 0.5% by weight. Furthermore, they also can be used to lubricate the auxiliary facilities on vessels Medium speed trunk piston engine oil: Features and benefits: 1) Perfect anti-emulsification and water separation properties 2) Outstanding oxidation stability to control the oxidation products effectively 3) Excellent detergency and dispersancy to assure the cleanness of piston and other parts 4) Superior cylinder ring and liner wear protection 5) Effectively neutralize acid substances formed during burning of fuel 6) Also can be used to lubricate diesel-driven dynamotors Recommended applications: 1) Suitable for medium speed four stroke trunk piston engines and crankcases or power plants burning high sulfur content fuels 2) T***0 and T***0 can be used for engines burning fuels with sulfur content less than 3.0% by weight, T***0 and T***0, less than 4.0% respectively
