This research aims to study and analyze the technical characteristics and practical performance of internal combustion engine oils (gasoline and diesel) and the effects of their viscosity in the Libyan context. The research focuses on analyzing the relationship between viscosity and temperature under Libya's diverse climatic conditions, while evaluating the properties of different oils and providing practical recommendations for selecting the appropriate oil. The study begins by explaining the fundamental properties of oils, specifically viscosity and its indicators (kinematic and dynamic), pour point, flash point, and total base number (TBN). It also covers the manufacturing process, starting from the vacuum distillation of crude oil, through the stages of solvent extraction and removal of asphalt and wax, and concluding with the addition of enhancing agents, detergents, dispersants, and other chemical additives that improve oil performance.
The research presents a comparative analysis of major global oil classifications, such as SAE, API, and ACEA, and links them to local needs in Libya, recommending multi-grade oils (e.g., SAE 10W-40) for their ability to adapt to thermal fluctuations between winter and summer. The research also discusses the main types of oils available in the market: mineral, synthetic, semi-synthetic, and high-mileage oils, highlighting the advantages and disadvantages of each. In the practical aspect, the research provides recommendations for oil change intervals (every 3,000–6,000 km depending on the season and conditions), while emphasizing the importance of periodic maintenance and using suitable oils for both old and modern engines. The research concludes by stressing the need to raise awareness among Libyan consumers about oil selection criteria, enhance market quality control, and conduct further field studies to evaluate the actual performance of oils under Libya's specific conditions.
