Fiat 9.5535-GS1

The FIAT 9.5535‑GS1 specification defines the requirements for a synthetic engine oil intended exclusively for gasoline engines of Fiat and Stellantis, including a range of models 500, Panda, Tipo, Ducato and their turbocharged variants. The oil must meet the viscosity 5W‑30/5W‑40, have high oxidation stability, effective wear protection and deposit control, and also provide a low SAPS content for safe catalyst operation. The specification provides compatibility with direct injection systems and, if needed, with DPF‑systems, allowing the preservation of the manufacturer’s warranty conditions. When selecting oil approved under FIAT 9.5535‑GS1, technicians and drivers obtain optimal fuel economy and extended engine life. This approval is also compatible with newer specifications such as FIAT 9.55535‑GSX, enabling seamless transition to updated products.
