Fiat 9.55535-S4

The FIAT specification 9.55535‑S4 sets requirements for synthetic engine oils that provide stable viscosity in the 5W‑30/5W‑40 range, high oxidation resistance and wear protection when operating in a wide temperature range. It is designed for gasoline engines of the new generations of Fiat, Alfa Romeo, Lancia and light commercial models, including turbocharged units with catalyst systems and particulate filters (DPF), where low SAPS content is important. Oil that meets 9.55535‑S4 guarantees long‑term combustion chamber cleanliness, reduced fuel consumption and support of the manufacturer’s warranty conditions. When selecting a product on xenum.ua, you should refer to approved lubricants, such as XENUM PRO‑C4 5W30, which have this approval and meet the requirements of modern FIAT engines.
