Low-friction motor oil, based on HC-Synthesis technology, suitable for passenger car petrol- and Diesel engines, with and without turbo-charging. Especially recommended for use in Mercedes and Opel engines. Due to the low sulfur and phosphor content, as well as the low ash-forming substances (Low SAPS) the optimal functionality of the exhaust after treatment system is guaranteed. It fulfils the new Long-life-requirements and therefore is suitable for long oil-change intervals.
