    摘要: A lubricant composition suitable for use as an automotive or industrial gear lubricant comprising:

    (A) from about 40 to about 85 wt%, based on the total weight of the lubricant composition, of an oil of lubricating viscosity;
    (B) from about 0.01 to about 5 wt%, based on the total weight of the lubricant composition, of a product obtainable by reacting at least one C 5 -C 60 carboxylic acid and at least one amine selected from guanidine, aminoguanidine, urea, thiourea and salts thereof; and
    (C) from about 2 to about 25 wt%, based on the total weight of the lubricant composition, of a gear additive package.

    摘要: A product obtainable by reacting:

    (i) a compound containing at least one primary or secondary amine group and at least one hydroxyl group;
    (ii) a polyamine containing at least two amine groups, which is different from (i), wherein at least one of the amine groups is a primary or secondary amine;
    (iii) an alkyl-substituted hydroxyaromatic compound; and
    (iv) at least one aldehyde,
       is useful in a hydrocarbon fuel as a detergent and also to enhance the lubricity of the fuel.
