Abstract
New lubricant additive compositions containing at least one alkenyl succinimide of the formula: ##STR1## in which R is an alkenyl group of C.sub.20 -C.sub.200, PA1 m is a whole number from 1 to 3, PA1 n is a whole number from 0 to 2, with PA1 m+n being from 1 to 3. They are produced from the reaction of an alkenyl succinic anhydride comprising a C.sub.20 -C.sub.200 alkenyl group and at least one amine of the formula: ##STR2## in which x is a whole number from 1 to 3. The additive compositions are useful in lubricating oils.
