Product Description:

GulfSea Cylcare EHP 5055is an extra high performance Marine Cylinder Lubricant (MCL) designed for the latest generation technology of low speed crosshead diesel engines operating with higher pressures, temperatures, longer strokes, and on wide range of residual fuels having sulphur content in the range of 1.0%wt to 3.5%wt. This lubricant is formulated with the latest leading edge technology and satisfies the most stringent requirements from OEM for this range of products.


Cylinder lubrication of the latest, highly rated low speed crosshead marine diesel engines operating on heavy fuels with sulphur content in the range of 1.0% to 3.5% (MARPOL regulation compliancy)
The recommended manufacturer’s feed rate should be maintained. Higher feed rates may be required during running-in. Click Here To Download PDF


ISO Grade 32, 46, 68, 100,150

Performance Level:

It meets and exceeds the requirements of MIL-L-17672C, DIN 51524 Part 1, Denision HF-1, Cincinnati Milacro n .

Features & Benefits

  • Latest in leading edge technology exceeding marine main engine maker (OEM)current requirements
    • Compliant with MARPOL regulation on marine fuel sulphur content
    • ECA’s on which fuel sulphur level is capped at 1.0
    • Global cap of sulphur content upto 3.5%
  • Enhanced anti-wear property minimizes piston ring & cylinder wear leading to reduced maintenance costs
  • Proven first class lubrication performance (without sacrificing corrosion control and detergency property even in low feed rate conditions) comparable with 70 BN lubricants
  • Excellent control of the cylinder corrosive pitting maintaining effective hydrodynamic lubricating film on cylinder wall when operating on low to moderate sulphur heavy fuel oils
  • Excellent detergency minimizing deposits on critical parts viz. pistons, piston rings, ring grooves and cylinder ports.
  • Excellent thermo-oxidative stability reducing deposit and sludge formation
