FIAT 9.55535-GSX

Specification FIAT 9.55535‑GSX is a requirement for synthetic motor oils for Fiat gasoline engines, developed by Stellantis to ensure stable operation of modern units with turbocharging, direct injection and high compression. Oil that meets this approval must have a viscosity range of 5W‑30/5W‑40, a minimum HTHS value ≥ 3.5 mPa·s, high oxidation resistance, wear protection and deposit control, as well as low SAPS content for safe operation of catalysts and diesel particulate filters (DPF). The specification covers a wide range of models—from Fiat 500, Panda, Tipo to the more powerful MultiJet‑II and MultiAir‑II, including light commercial variants. When selecting oil on xenum.ua, you should look for products bearing the FIAT 9.55535‑GSX label, such as XENUM ECO PRO DX1 0W20 or 5W20, which guarantees compliance with warranty conditions and increased engine durability. Newer approvals FIAT 9.55550‑AV5 and similar also meet or exceed the requirements of 9.55535‑GSX, allowing safe transition to them when needed.
