Engine Oils

Eni offers a wide range of high-tech lubricants, to satisfy the requirements of all car engines.

Whether in city cars, in flagships or in sports cars, powered by petrol or diesel, the Eni lubricants perform with the highest reliability in every condition of use.

Eni lubricants comply with the most recent and strict specifications of constructors and international regulators and consequently assure the best protection and conservation of every part of the engine.

The lubrication of internal combustion engines is more complex than that of any other machine, due to the extreme variability of load conditions, speed, temperature and variety of materials.

Diesel engines (with compression ignition) and petrol engines (with spark ignition) have many lubrication problems in common but each has its own critical areas, connected not only to the thermal cycle but also to operational conditions: the petrol engines are typically motor car engines, those which are diesel are also commercial and industrial vehicles (lorries, building site vehicles, tractors, coaches, etc.).

The quality of a motor oil is defined by the performance tests run on the engines on the test bed and often with tests on vehicles (fleet tests).
The test on engines on the test bed are performed in particularly severe conditions, following standardized procedures which simulate critical operation situations.
Other tests, with laboratory equipment, define the viscosimetric characteristics and compatibility with materials (gaskets, etc.)
