Fiat 9.55535-M2

The FIAT specification 9.55535‑M2 defines the requirements for a synthetic motor oil that provides a viscosity of 5W‑40, high oxidation stability, wear protection and engine cleanliness across a wide temperature range. It is developed for FIAT gasoline engines with a displacement of 1.2–1.6 L, including turbocharged MultiJet II and MultiAir, as well as for passenger crossovers and small commercial models where catalysts and diesel particulate filters (DPF) are used. Oil approved under 9.55535‑M2 meets ACEA A3/B4 requirements and has a low SAPS content, allowing safe operation with modern after‑treatment systems without risk of catalyst fouling. Using such oil guarantees compliance with Stellantis warranty conditions, extends engine life and reduces fuel consumption, which is especially important for professional workshops and enthusiasts servicing Fiat Panda, 500, Tipo and Ducato models.
