Beschreibung
Zusammenfassung:	A cylinder lubricant having a BN determined according to the standard ASTM D-2896 greater than or equal to 15 milligrams of potash per gram of lubricant, including: one or more lubricant base oils for marine engines, at least one detergent based on alkali or alkaline-earth metals, overbased with metallic carbonate salts, at least one neutral detergent, one or more oil-soluble alkoxylated fatty amines, having a BN determined according to the standard ASTM D-2896 comprised between 100 and 600 milligrams of potash per gram, where the percentage by mass of alkoxylated fatty amines with respect to the total weight of lubricant is chosen such that the BN provided by these compounds represents a contribution comprised between 2 and 8 milligrams of potash per gram of lubricant, and where the BN provided by the metallic carbonate salts represents a contribution of at the most 65%.
