Fiat 9.55535-DS1

The FIAT 9.55535‑DS1 specification defines the requirements for synthetic motor oil aimed at modern Fiat diesel engines with turbocharging and diesel particulate filter (DPF) systems. Oils that meet this approval must have a viscosity range of 0W‑30/5W‑30, high oxidation stability, excellent wear protection, and maintain a low SAPS level, which prevents fouling of the DPF and catalyst. Technical parameters include a low pour point, high ability to keep cylinders clean, and effective operation over a wide temperature range. The specification is intended for gasoline and diesel power units of passenger, crossover, and light commercial Fiat models, including 1.3 L, 1.6 L and 2.0 L turbocharged engines. Using oil approved under FIAT 9.55535‑DS1 ensures compliance with the manufacturer's warranty conditions and extends engine life and efficiency.
