ALESTA H 4060

ALESTA H 40-60 is a premium-quality, medium-speed trunk-piston diesel engine oil developed for marine and stationary diesel engines operating under severe conditions. It is specially formulated for engines using residual fuel with a sulfur content of up to 4.5%, where strong acid neutralization and sludge control are critical in such applications.
Compared to products with lower BN values, ALESTA H 40-60 offers a higher alkalinity reserve, making it particularly suitable for engines exposed to high acid formation and operating under more severe conditions. Its advanced formulation combines high detergency, effective dispersant properties, and superior oxidation resistance to control deposits forming on pistons, piston ring areas, and undercrown regions, helping to maintain overall engine cleanliness. This product is specifically recommended for medium-speed trunk-piston engines with low oil consumption. It provides reliable lubrication in applications where maintaining alkalinity over long service intervals is critical, minimizes wear, and delivers consistent protection in engines operating under continuous heavy loads. ALESTA H 40-60 is suitable for use in marine propulsion systems, auxiliary engines, and power generation equipment—particularly in applications requiring higher BN performance due to fuel quality or harsh operating conditions.

ALESTA H 40-60 has been developed to provide superior protection against harsh operating conditions in medium-speed marine diesel engines running on high-sulfur and residual fuels. It delivers reliable performance, particularly in ship main propulsion systems, auxiliary engines, and stationary power generation units. Thanks to its strong neutralization capability in applications with high acid loads, it effectively manages deposit control in the piston group, ring areas, and under-piston regions. It is suitable for use in marine and industrial engines operating under continuous high loads, where maintaining alkalinity reserves over long service intervals is critical.
