Fiat 9.55535-S2

The FIAT 9.55535‑S2 specification defines the requirements for a synthetic 5W‑40 motor oil that must meet API SN/CF, ACEA A3/B4 and have high oxidation stability, low viscosity loss at 150 °C and excellent wear and corrosion protection. It is designed for modern FIAT gasoline engines with MultiAir technology and turbocharging, installed in passenger models (Punto, 500, Tipo, 500 X) and light commercial vehicles, including engines of 1.2‑2.0 L. The specification calls for compatibility with catalysts and after‑treatment systems, therefore the oil has a low SAPS content, preventing catalyst fouling. Adhering to these parameters ensures stable engine operation, reduced fuel consumption and extended oil‑change intervals. When selecting a product on xenum.ua, you should look for oils bearing the FIAT 9.55535‑S2 marking, such as XENUM X1 5W40 or XENUM PRO‑S 5W40.
