Synplus LL-12 0W/30 is an advanced, fully synthetic engine oil with mid SAPS (Sulfated Ash, Phosphorous, and Sulfur) content, specifically engineered for extended drain intervals and super high performance. This oil leverages cutting-edge oil formulation and additive technology to offer the highest level of engine protection, with a special focus on vehicles equipped with smaller engines susceptible to Low-Speed Pre-Ignition (LSPI) and those featuring catalyzed exhaust systems.

Synplus LL-12 0W/30 is exceptionally well-suited for use in modern BMW turbo diesel engines and certain petrol engines that do not require particulate filters but demand BMW LL-12 FE performance. It’s also an excellent choice for a range of car and light van diesel engines with catalytic converter exhaust systems, designed to harness the benefits of a low-viscosity oil with a high-temperature/high-shear rate (HTHS) viscosity of at least 2.9 mPa-s.

In today’s environmentally conscious automotive market, where reducing emissions and enhancing fuel efficiency are paramount, new engine designs have emerged, necessitating higher-quality lubricants. Smaller, higher-output engines, developed to meet stringent fuel economy standards, pose specific challenges to lubricants:

• Increased Heat: Smaller engines generate elevated temperatures, accelerating the rates of oil oxidation, nitration, and deposit formation. This degradation of the oil promotes the formation of acidic compounds and leads to increased viscosity.

• Increased Pressure and Speed: These engines operate at higher pressures and speeds, making it more challenging for the oil to maintain a lubricating film that prevents metal-on-metal contact. This accelerated wear predominantly affects components like the valve train.

• Emission Control: Many contemporary petrol engines come equipped with catalytic converters to reduce emissions of CO, NOx, and unburned carbon. However, catalytic converters are sensitive to SAPS (Sulfated Ash, Phosphorous, and Sulfur) found in engine oil detergents, antiwear additives, and base oils.

Synplus LL-12 0W/30 is expertly designed to address these specific demands and challenges, delivering exceptional protection and performance for engines, promoting environmental compliance, and ensuring extended engine life.
