Quartz Ineo Xtra EC6 0W-20 is an advanced synthetic engine oil of superior performance designed for the newest generation of engines of premium car manufacturers. Its cutting-edge technology reduces friction to its minimum, contributing to the exceptional fuel economy performance of the engine. Quartz Ineo Xtra EC6 0W-20 meets the latest ACEA C6 standard, and API SP (RC) performance standard, providing protection against LSPI (Low Speed Pre-ignition), a phenomenon in some ways similar to knock and which can damage the engine. Today car manufacturers develop engines which are smaller, run at a lower speed, and still deliver the same power therefore develop higher power density that favors LSPI events.
