Fiat Oil Specifications

Fiat approvals are used when selecting engine oils for Fiat, Alfa Romeo, Lancia, Abarth, Maserati.

Fiat Approvals

To obtain Fiat approval, the engine oil is tested in the laboratory and tested in the engines. Laboratory tests assess viscosity, flow, aggressiveness to rubber and plastic parts, oxidation resistance, foaming and corrosion characteristics. In-engine tests assess the real behaviour and properties of the oil under real operating conditions: deposit formation on parts, wear of metal surfaces, oil burn-in consumption.

Fiat Oil Specifications

The company’s experts have invested a great deal of resources in determining which chemical characteristics of oils are considered essential. As a result of lengthy research in modern laboratories, it became clear that the main quality criteria for Fiat are considered to be:

  • Foaming degree;
  • Viscosity values;
  • Stability;
  • Resistance to oxidation;
  • Resistance to corrosive processes;
  • Stability at low temperatures.

Fiat engine oil performance tests focus on the physical characteristics of the fluid, its ability to reduce friction and wear on rubbing surfaces, and to protect the piston from deposit formation.


What is a Fiat specification?

The Fiat specifications are symbolic descriptions of the properties of engine oil for a specific type of Fiat vehicle, and it is according to these specifications that you select the oil for your Fiat vehicle. By selecting oil according to the appropriate specification, you guarantee that you are using the correct oil for your Fiat.

Fiat Engine Oil Approvals

These qualification requirements define the characteristics that lubricants used in Otto and Diesel cycle engines must meet when first filling and during operation. The standard consists of a series of tests in the laboratory and on the engine to assess the level of performance of the lubricants. In laboratory tests the lubricant is assessed for viscosity, cold yield strength, tendency to foam, copper tongue corrosion, behaviour with rubber and resistance to oxidation. Engine tests assess the level of lubricant performance in terms of ring sticking, piston deposits, wear and tear, as well as oil consumption in certain diesel and petrol engines, which are the most representative of Fiat Auto’s most advanced technologies.
