Lube oil additives are essential for all types of lubricating oils; they are added either to give the oils new properties as detergency and oxidation stability or to improve such properties as pour point and viscosity index. They are added at varying proportions to meet the performance requirements. The present work is concerned with studying of detergent/dispersant type additives based on synthesized polyisobutylene succinic anhydride (PIBSA) and its aminated compounds (PIBSA) with different types of polyethylene polyamine such as ethylene diamine, diethylene Triamine, Triethylene tetramine, and tetraethylene pentamine. Different types of polyisobutylene succinimides were reacted with dodecylphenol and formaldehyde to prepare different type of Mannish bases. The efficiency of the prepared compounds as antioxidants and detergents/dispersants was investigated. It was found that compound D1 (Mannich base IV) is the best antioxidant additive for lube oil, and all the prepared compounds have excellent dispersancy power.
