The paper presents the results of a laboratory study on the influence of four compactive efforts, (i. e., British Standard Light, BSL, West African Standard, WAS and British Standard Heavy, BSH) on the compaction characteristics of oil contaminated soil. The lateritic soil was contaminated with petroleum oil product between 2-6% oil content by weight of dry soil. The results showed that the maximum dry density of the oil contaminated soil decreased with higher compactive effort. The maximum dry densities (MDD) of the natural soil for RBSL, BSL, WAS and BSH compactive efforts are 1.66, 1.82, 1.89 and 2.0 Mg/m3, respectively. Samples contaminated with 6% oil content yielded lower MDD values of 1.62, 1.72, 1.75 and 1.81 Mg/m3. In the same vein, the optimum moisture content (OMC) increased slightly with higher oil content.
