Fiat 9.55535-DSX

Specification FIAT 9.55535‑DSX is an OEM approval from Stellantis for diesel engines, developed taking into account the requirements of modern after‑fuel treatment systems, including diesel particulate filters (DPF) and catalysts. It calls for the use of synthetic oil with high oxidation stability, excellent wear protection and low SAPS content, which ensures minimal carbon buildup and extends DPF service life. The specification covers diesel units of 1.3‑2.0 L installed in Fiat Ducato, Fiat Tipo, Fiat Fiorino and light commercial Jeep versions, as well as in some turbocharged Stellantis engines. Compliance with the 9.55535‑DSX requirement guarantees compatibility with the manufacturer's warranty conditions, optimal fuel economy and reduced emissions. When selecting oil on xenum.ua, you should look for products that are explicitly marked with this specification, for example XENUM DIESEL SYNTH 10W40.
