QUARTZ INEO FIRST 0W-30 is used by Stellantis (ex-PSA Group) as First fill engine oil and is recommended by PEUGEOT, CITROËN, DS, OPEL and VAUXHALL in after sales (PSA B71 2312 & 2302 specifications). QUARTZ INEO FIRST 0W-30 is also meeting the stringent requirements of Fiat 9.55535-DS1 and Fiat 9.55535-GS1. Additionally, our engine oil is also adapted to engines requiring the Fiat 9.55535-DSX specification (as an alternative). This pollution-control synthetic technology engine oil provides engines with the best possible protection against wear and clogging. The post-treatment systems, sensitive to the lubricants used and expensive to maintain, are also protected over the long-term thanks to the “Low SAPS” formulation (low content of sulphated ash, phosphorus and sulphur contents). Using this engine oil can help generate fuel savings without the need to change driving style. QUARTZ INEO FIRST 0W-30 is particularly well-suited for use with recent engines of Stellantis/PSA, and particularly ones equipped with e-HDI using Stop & Start technologies, and hybrid engines which require new-generation engine oils.
