Abstract

New lubricant additive compositions containing at least one alkenyl succinimide of the formula: ##STR1## in which R is an alkenyl group of from about 20 to 200 carbon atoms and m is a whole number 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 tris(5-amino-3-thia-pentyl)amine. The additive compositions are useful in lubricating oils.
