This low friction motor oil is based on hydrocrack oils (HC- Synthesis) for Otto and Diesel motors with and without Turbo-charge, especially recommended for use in Opel motors. By the low sulfur and phosphor content, as well as the low cinder forming substances (Low SAPS) the optimal functionality of the exhaust after treatment system is guaranteed. It fulfills the new Long-life-requirements and therefore is suitable for oil-change intervals.
