Description

Eni i-Sigma monograde HBN SAE 10W is a single-grade engine oil from the i-Sigma monograde line for turbocharged and naturally aspirated diesel engines in severe service, including those running on high-sulphur fuel. It is also used in the hydraulic systems of tractors and earth-moving machines that specify an oil of this type.

The oil is rated API CF and API SJ; the data sheet lists no official manufacturer approvals.

Typical figures: kinematic viscosity 5.5 mm²/s at 100 °C, viscosity index 110, base number 11.5, pour point -27 °C, flash point 240 °C, density 880 kg/m³.

Application

Turbocharged and naturally aspirated diesel engines in severe service, including on high-sulphur fuel; also the hydraulic systems of tractors and earth-moving machinery that call for this type of oil.

Worth knowing

This oil passes the cold limit of the 10W grade with a small margin: Eni gives a cold-cranking viscosity of 6,800 mPa·s at -25 °C (ASTM D 5293 method), whereas SAE J300 allows no more than 7,000 mPa·s for 10W at that temperature. At 100 °C the grade requires at least 4.1 mm²/s, and the oil has 5.5 mm²/s. Both limits, together with those of the remaining grades, are collected in the table of SAE viscosity values.

The data sheet gives the same value at -25 °C for Eni i-Sigma monograde 10W-20, but Eni intends that oil for diesels in light-duty service, gives no base number for it and, unlike the HBN SAE 10W, states compliance with Allison C-3, MIL-L-2104D and MIL-L-46152C. The HBN SAE 40 of the same line also has a base number of 11.5 mg KOH/g and the API classes CF and SJ, but at 100 °C it has 14.4 mm²/s, which is SAE grade 40.
