These engine oils are distinguished by their notably low ash content. The low ash content plays a critical role in minimizing the formation of engine deposits, including ash deposits, in the combustion chamber and exhaust system. Excessive ash content can lead to detrimental buildup that can reduce engine efficiency. By maintaining a low ash content, these engine oils help ensure the engine remains clean and operates at peak performance throughout their service life.

These engine oils offer exceptional resistance to oxidation and corrosion. Oxidation resistance is crucial as Arum T-MONO SAE 50 prevents the oil from breaking down due to exposure to high temperatures and oxygen. Corrosion resistance ensures that critical engine components remain protected from harmful corrosive elements. By maintaining these protective properties, these engine oils effectively safeguard the engine's vital parts, such as pistons, bearings, and valves. This protection significantly contributes to prolonged engine life, improved overall performance, and reduced maintenance requirements.

These engine oils are formulated using natural, paraffinic base oils from group I, combined with carefully crafted special additive packages. The base oils, specifically group I paraffinic oils, serve as the foundation for these engine oils, providing excellent lubrication and stability properties. The special additive packages incorporated into the formulation enhance the oils' performance characteristics. These additives typically include anti-oxidation agents, corrosion inhibitors, and detergents. Together, the base oils and additives create a well-balanced formula that effectively protects against oxidation and corrosion while ensuring the engine operates smoothly and efficiently.

The higher SAE 50 grade is especially effective in regions where engines are subjected to high tropical circumstances. In such areas, where temperatures remain consistently high, engines experience increased stress and heat. The use of SAE 50 grade oil provides a thicker viscosity, which is essential for maintaining adequate lubrication and engine protection under these challenging conditions. This helps ensure the engine operates efficiently, minimizes wear and tear, and contributes to the longevity of the engine.

These engine oils are exceptionally versatile and well-suited for a wide variety of engines commonly found in the more traditional car portfolio. They are ideal for naturally aspirated, turbocharged, or supercharged diesel engines that operate in moderate to severe-duty service conditions. Additionally, they are suitable for specific heavy-duty gasoline engines. This versatility makes them an excellent choice for various automotive applications, ensuring that they can deliver reliable performance and protection across a range of vehicles.

These engine oils have been certified with the API SF/CD specification, indicating that they meet stringent quality standards set by the American Petroleum Institute (API) specifically for passenger car engine oils. This certification ensures that these oils provide optimal performance and protection for a wide range of engines found in traditional cars. The API SF/CD specification encompasses engines with typical service characteristics, including naturally aspirated, turbocharged, or supercharged diesel engines operated in moderate to severe-duty service, as well as certain heavy-duty gasoline engines.
