ABSTRACT:
New lubricating oil additives are provided comprising the reaction product of a hydroxy compound, such as an alcohol or hydroxyaromatic compound, with an aliphatic chain substituted-carboxylic anhydride, acid, chloride, or ester, which aliphatic chain substituent is substantially saturated and contains at least about 30 carbon atoms, said reaction product being neutralized with an ashless basic compound, so that the final product or additive contains at least about 0.9%, up to about 2.5%, by weight of nitrogen. Lubricating oils, fuel oils, and carburants containing the new additives have excellent detergent, dispersing and anti-rust properties.
