New lubricant additive compositions containing at least one alkenyl succinimide of the formula: <IMAGE> in which R is an alkenyl group of C20-C200, m is a whole number from 1 to 3, n is a whole number from 0 to 2, with m+n being from 1 to 3. They are produced from the reaction of an alkenyl succinic anhydride comprising a C20-C200 alkenyl group and at least one amine of the formula: <IMAGE> in which x is a whole number from 1 to 3. The additive compositions are useful in lubricating oils. |
