These engine oils are distinguished by their notably low ash content, a key attribute that plays a pivotal role in minimizing the formation of engine deposits, including ash deposits, within 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 that the engine remains clean and continues to operate at peak performance throughout their service life.

These engine oils are engineered to offer outstanding resistance to both oxidation and corrosion. Oxidation resistance is particularly critical as Dahlia T-MULTI SAE 15W/40 prevents the oil from breaking down due to exposure to high temperatures and oxygen. Corrosion resistance ensures that essential engine components remain shielded from harmful corrosive elements. By maintaining these protective properties, these engine oils effectively safeguard the engine's vital parts, including pistons, bearings, and valves. This comprehensive protection significantly contributes to prolonged engine life, improved overall performance, and reduced maintenance requirements.

These engine oils are meticulously formulated using natural, paraffinic base oils from group I, which are combined with carefully crafted special additive packages. The base oils, specifically group I paraffinic oils, serve as the fundamental building blocks for these engine oils, delivering excellent lubrication and stability properties. The special additive packages integrated 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 15W/40 grade is particularly effective in regions where engines are exposed to high tropical circumstances. In such areas, where temperatures remain consistently high, engines endure increased stress and heat. Utilizing SAE 15W/40 grade oil is crucial because Dahlia T-MULTI SAE 15W/40 provides a balance of viscosity that ensures proper lubrication and engine protection under these challenging conditions. This contributes to efficient engine operation, minimizes wear and tear, and promotes the longevity of the engine.

These MULTIGRADE engine oils are extremely versatile and ideally suited for a wide variety of engines commonly found in the more traditional car portfolio. They are well-suited for naturally aspirated, turbocharged, or supercharged diesel engines that operate under moderate to severe-duty service conditions. Additionally, they are appropriate for specific heavy-duty gasoline engines. This versatility ensures that these oils can provide reliable performance and protection across various automotive applications.

These MULTIGRADE engine oils hold the important API SF/CD specification, signifying that they meet the rigorous quality standards set by the American Petroleum Institute (API) for passenger car engine oils. This certification assures users that these oils are engineered to deliver top-notch performance and protection for a diverse range of engines typically found in traditional cars. The API SF/CD specification encompasses engines with typical service characteristics, including naturally aspirated, turbocharged, or supercharged diesel engines that operate in moderate to severe-duty service, as well as certain heavy-duty gasoline engines.
