This is an ultramodern full synthetic engine oil suitable for turbocharged gasoline direct-injection (TGDI) engines and is known for its API SP / ILSAC GF-6 specification. This engine oil ensures superior Fuel Economy properties, compared to products with the older API SN PLUS and API SN specification. It is specifically developed in order to prevent LSPI (Low Speed Pre-Ignition). LSPI is very common when a vehicle is driving slowly and suddenly accelerates rapidly. As a result, particles of fuel and oil will ignite in the combustion chamber.
