Description

Eni i-Sigma monograde CC SAE 50 is a single-grade engine oil from the i-Sigma monograde line for naturally aspirated and mildly turbocharged diesel engines. Some fleets use it as a single oil for both diesel and petrol engines. Its detergent-dispersant performance is at the basic level suited to engines of earlier generations.

The oil is rated API CC and API SC and meets the military specification MIL-L-2104B. The data sheet lists no official manufacturer approvals.

Typical figures: kinematic viscosity 255 mm²/s at 40 °C and 20.7 mm²/s at 100 °C, viscosity index 95, base number 6.2, pour point -24 °C, flash point 251 °C.

Application

Naturally aspirated or mildly turbocharged diesel engines; in some cases a single oil for mixed fleets of diesel and petrol engines.

Worth knowing

The order in the API CC/SC entry is not accidental: the manufacturer lists first the class for the application it considers primary, so for this oil diesel engines come first and petrol SC is secondary. API counts both classes as obsolete, along with all petrol classes up to SH and diesel classes up to CG-4, and they are not suitable for modern engines.

If your engine’s documentation names API CF and you need the same viscosity grade, SAE 50, the line has Eni i-Sigma monograde SAE 50 with the classes API CF and API SJ; its data sheet names MIL-L-2104D and MIL-L-46152C in place of MIL-L-2104B. The article “Decoding the API code” shows how to read a double class on the label and what the letters S and C stand for.
