Abstract: New lubricating oil additives are provided comprising the reaction product of diphenylolpropane with an aliphatic chain substituted-succinic anhydride or acid, which aliphatic chain substituent is substantially saturated and contains at least about 30 carbon atoms, said reaction product being neutralized with an amine, preferably a polyamine, such as a polyalkylenepolyamine. Lubricating oils, fuel oils, and carburants containing the new additives have excellent detergent, dispersing and anti-rust properties.
