Abstract: Soil contamination by engine oil causes huge damage to the environment. This basically takes place due to oil exploration, transportation, production and processing, leakage of diesel products from oil tankers, spills due to vehicular accidents, from buried pipelines etc. The hydrocarbons present in the oil influences the quality and physical properties of oil contaminated soil. These hydrocarbons infiltrate into the soil through pore spaces and collect at the top of the ground level. Some major tasks need to be performed for remediation and reclamation of contaminated area. For this knowledge of the geotechnical properties and behavior of contaminated soils is required. This study aimed to investigate the geotechnical properties of engine oil-contaminated sandy soil. The amount of oil added to soil was varied at 0%, 4%, 8% and 12% of the dried weight of samples. Results showed that the oil contamination decreased the liquid limit, plastic limit. The MDD value was found to be decreasing whereas value of OMC was increasing as a result of increasing amount of added oil into the soil. This indicates that the addition of oil has adverse effects to the geotechnical properties of the studied soil. This affects the safety of civil engineering structures. The results from the study will be used for geotechnical purposes and will benefit engineers for the safe and economic construction of structures on contaminated land.
