ABSTRACT:
A lubricant composition comprising a major amount of a lubricating oil and an effective dispersant amount of both a hydrocarbyl-substituted mono- and bis-succinimide having polyamine chain linked hydroxyacyl radicals, and a polyol derivative prepared by contacting an aliphatic polyolefin with P.sub.2 S.sub.5 in the presence of sulfur and P.sub.2 S.sub.5, contacting the resultant polyolefin-P.sub.2 S.sub.5 reaction product with a steam, removing inorganic phosphorus acid from the steam treated polyolefin P.sub.2 S.sub.5 reaction product, and contacting the polyolefin P.sub.2 S.sub.5 reaction product with a neopentyl polyol. The combination of succinimide and polyol derivative exhibit enhanced dispercancy and/or detergency over either additive alone.
