GulfSea Power Series
Marine Trunk Piston Engine Oil specially designed for modern Medium Speed 4-stroke Marine
Diesel Engines running on Intermediate Fuel Oil (IFO) or Heavy Fuel Oil (HFO)
Product Description
GulfSea Power is a trunk piston engine oil designed for use in medium speed diesel
engines operating on residual fuels in marine, power generation ａnd industrial applications.
The superior additive technology used in this oil provides excellent engine cleanliness & wear
protection under different operating conditions. This oil is available in SAE 30 & 40 viscosity
grades with a BN (Base Number) ranging from 30 to 55. These oils exhibit a high degree of
water tolerance ａnd have better water separation ａnd base retention properties. These oils meet
the performance requirements of API CF.
Features & Benefits
• Excellent detergency ａnd dispersancy reduces build-up of soot & black sludge ａnd keeps
the engine cleaner.
• Acidic by-products are effectively neutralised ａnd the engine is protected from corrosive
wear.
• Better demulsibility characteristics ensure water separation leading to trouble free
operation.
• Robust anti-wear technology provides protection against piston & linear wear ａnd good
gear performance leading to reduction in maintenance costs.
• Improved thermo-oxidative stability retards oil degradation facilitating extended oil life.
Applications
• Recommended for medium speed diesel engines in marine, power generation and
industrial applications operating on residual fuels.
• GulfSea Power 3055 & 4055 with a BN of 55 are specifically formulated for engines
operating on high sulphur residual fuels. These oils are also specially
recommended for those engines where the frequency of topping-up/replenishment is less
frequent.
• GulfSea Power 3040 & 4040 with a BN of 40 are suitable for engines operating on
residual fuels having sulphur content in excess of 3.5%
• GulfSea Power 3030 & 4030 with a BN of 30 are suitable for engines operating on
residual fuels having sulphur content in excess of 2.5% ａnd up to 3.5 %
• Also recommended for general lubrication of shipboard equipment where specialised
lubricants are not required or use of API CF quality oils are adequate
