Cylinder Oil
YANMAR Marine have full series of slow speed diesel engine oils, which is developed with heavy base stock and specially designed additive control. Two segments of this series are formulated for two very different applications, first is the OSOI and the second is the SHISUTEMU. Both are termed high performance lubricants and provide enhanced protection from mechanical wear as well as mitigation of cold corrosion. They are fully capable to optimize feed rates and reduce operating cost.
OSOI 50-25
YANMAR OSOI 50-25 marine cylinder oil for slow-speed 2-stroke engines running on ECA fuels below 0.1% sulfur,is a highly reliable low alkaline lubricant, ensuring reliable operations with ECA compliant ultra low sulphur fuels, provides excellent cleanliness and outstanding deposit control, its low-ash content are protected against deposit formation which can lead to scuffing issues.YANMAR OSOI 50-25 meets the requirements of Japan Engine Corporation, MAN ES and WinGD
SAE Grade: 50 TBN 25
OSOI 50-40
YANMAR OSOI 50-40 marine cylinder oil for slow-speed 2-stroke engines running on ECA fuels using low sulfur residual fuels below (1.0% sulfur), It’s special formulation to maintains engine cylinder cleanliness and minimizes deposit build-up on piston crowns, rings and liners, With its low BN and its conventional calcium carbonate chemistry, it is optimized to efficiently lubricate engines. YANMAR OSOI 50-40 meets the requirements of Japan Engine Corporation, MAN ES, and WinGD.
SAE Grade: 50 TBN 40
OSOI UNIVERSAL 50-57
YANMAR OSOI UNIVERSAL 50-57 marine cylinder oil for all 2-stroke engines using fuels and Dual Fuel with a sulfur range of 0.0 to 1.5%. the single oil solution, designed to lubricate engines using a wide range of fuels. Chemistry ensures optimum engine cleanliness and efficient acid neutralization.YANMAR OSOI UNIVERSAL 50-57 meets the requirements of Japan Engine Corporation, MAN ES, and WinGD.
SAE Grade: 50 TBN 57
OSOI UNIVERSAL 50-70
YANMAR OSOI 50-70 marine cylinder oil for slow-speed 2-stroke engines running on high sulfur fuel oils,Using conventional mineral chemistry, its high BN efficiently neutralises sulphuric acid formed during combustion of high sulphur residual fuels, this prevents corrosion, cylinder wear and scuffing, and can extend the length of time between engine overhauls, it can work in various operating conditions.YANMAR OSOI 50-70 meets the requirements of Japan Engine Corporation, MAN ES, and WinGD.
SAE Grade: 50 TBN 70
OSOI UNIVERSAL 50-100
YANMAR OSOI 50-100 is designed exclusively for modern Tier II and Tier III engines using high sulphur residual fuel oil, and has a high BN of 100, allowing for the most stringent and corrosive service conditions. It is capable of keeping engine cylinders clean and preventing engine damage when high sulphur heavy fuel oils (HSHFOs) are used, as well as when the engine is operated over extended periods of intense operation. YANMAR OSOI 50-100 meets the requirements of Japan Engine Corporation, MAN ES, and WinGD.
SAE Grade: 50 TBN 100
OSOI 50-100
YANMAR OSOI 50-100 marine cylinder oil BN 100 for slow-speed 2-stroke engines running on any fuel oils in the range 0,0% to 3,5% sulfur, the innovative formulation using Ashfree Neutralizing Molecules provides superior acid neutralization and outstanding cylinder cleanliness, exceeding the capability of conventional oil. YANMAR OSOI 50-100 meets the requirements of Japan Engine Corporation, MAN ES, and WinGD.
SAE Grade: 50 TBN 100
OSOI 50-140
YANMAR OSOI 50-140 marine cylinder oil for slow-speed 2-stroke engines especially suitable for those known to be susceptible to the cold corrosion phenomenon.YANMAR OSOI 50- 140 is able to efficiently neutralise sulphuric acid formed during combustion of high sulphur residual fuels whilst ensuring optimum engine cleanliness and minimising component wear. It is also suitable for use in on-board Mixing Systems when used in conjunction. YANMAR OSOI 50-140 meets the requirements of Japan Engine Corporation, MAN ES, and WinGD.
SAE Grade: 50 TBN 140
