Engine oil is a vital component of a vehicle’s lubrication system. Over time, oil has evolved beyond just lubrication it now plays a role in reducing friction, controlling engine temperature, and preventing wear. One of the key innovations enhancing oil performance is the use of additives, which have become the focus of many scientific studies.
This study aims to evaluate the effects of adding additives to engine oil on lubrication performance and oil service life. The focus is on four types of additives: detergents, anti-wear agents, antioxidants, and friction modifiers.
Laboratory tests were conducted using ASTM standards. Both additive-enhanced and standard oils were tested for viscosity, wear index, and thermal stability at 100°C for 120 hours. A tribology testing machine was used to measure metal wear and the stability of the lubricant.
The results showed that oil with additives reduced metal wear by up to 35% compared to standard oil. It also demonstrated an 18% improvement in viscosity stability and higher resistance to oxidation. These findings indicate that additives significantly enhance the durability and efficiency of engine oil.
The study confirms that adding additives to engine oil improves lubrication performance, extends oil life, and protects engine components. The inclusion of additives is highly beneficial and is strongly recommended for use in the automotive lubricant industry.
