An additive for lubricating oils for diesel engines, comprising one or more kinds of amino alcohols which have one or more amino groups and one or more hydroxyl groups in a molecule and possess a function of dispersing water-containing calcium sulfate in oil, the hydroxyl groups being bound to the carbon atoms at the .beta.-positions to the amino groups; and a lubricating oil composition for diesel engines, which comprises the additives in an amount of from 0.1 to 10% by weight.

Additive for lubricating oils for diesel engines and lubricating oil

An aqueous solution composition of a strong alkali and a nonionic surface active agent comprising: (a) a strong alkali, (b) a nonionic surface active agent having an HLB value of 3-18, and, as a solubilizing agent, (c) a specific type of carboxylic acid is disclosed. The composition contains a strong alkali and a nonionic surface active agent having an HLB value usually of 3-18 at high concentrations and stably and is homogeneous and transparent. Thus, it is useful for a variety of applications requiring both alkalinity and detergency, for example, as wettability promoting agents of glass, fiber, metal, and earthenware surfaces as well as various toiletry products.
