Synplus LL-12 0W/30 is a full synthetic, mid SAPS, long drain super high performance engine oil which combines the latest development in oil formulation and additive technology to provide a lubricating oil with the highest level of protection, especially for vehicles with smaller engines at risk of LSPI and those with catalysed exhaust systems.
Synplus LL-12 0W/30 is especially suited for use in modern BMW turbo diesel engines and those petrol engines without particulate filters requiring BMW LL-12 FE performance; as well many car and light van low friction diesel engines with catalytic converter exhaust systems designed to be capable of using a low viscosity oil with a high temperature/high shear rate (HTHS) viscosity of 2.9 mPa-s minimum.
Today’s environmentally conscious market demands reduced emissions and increased fuel efficiency. This has led to the development of new engine designs resulting in demands for higher quality lubricants. In recent years car manufacturers have developed smaller, higher output engines to meet stricter fuel economy limits. Small engines help decrease vehicle weight and improve economy but these engines impact lubricants through:
- Increased heat – accelerates the rate of oil oxidation, nitration and deposit formation. This degrades the oil and encourages the creation of more acid and increases viscosity.
- Increased pressure and speed – makes it harder for the oil to maintain a lubricant film to prevent metal on metal contact. This accelerates valve train wear.
- Emission Control – most of today’s petrol engines are fitted with catalytic converters which reduce emissions of CO, NOx and unburned carbon. Catalytic converters are susceptible to SAPS (Sulfated Ash, Phosphorous and Sulfur) that are present in engine oil detergents, antiwear additives and in base oils.
Synplus LL-12 0W/30 is designed to overcome these challenges to the vehicle’s lubricant system.
