Description

Eni i-Sigma universal 15W-40 is a multigrade engine oil from the i-Sigma universal line for mixed fleets. It is intended for diesels in lorries, buses, construction machinery, vans and cars in severe service, as well as for petrol engines.

The oil is rated ACEA E2 and API CG-4 and SL. The list contains no official approvals: the maker states that it meets the requirements of MAN 271, MB 228.1 and MB 229.1.

Typical figures: kinematic viscosity 14.5 mm²/s at 100 °C, viscosity index 140, base number 9.1 mg KOH/g, pour point -27 °C, flash point 220 °C.

Application

Diesel engines in lorries, buses, construction machinery, vans and cars in severe service; also suitable for petrol engines, so it fits mixed fleets.

Worth knowing

Of this oil’s two API classes, API has already declared the diesel CG-4 obsolete; in its place, as the article “API CG-4 Class” explains, API expressly allows CH-4, CI-4 and CJ-4 oils. The list also has the petrol SL and ACEA E2, while Eni claims MB 228.1, MB 229.1 and MAN 271 without an approval.

A lorry’s service book may name ACEA E7 or a Volvo VDS-3 approval for 15W-40; the brand has them in Eni i-Sigma performance E7 15W-40. Volvo VDS-3, Mack EO-N, Renault Trucks RLD-2, Deutz DQC III-18 and MTU Oil Category 2 are marked there as approved, and the API classes go up to CI-4. That oil, however, has no entries for MB 228.1, MB 229.1 or MAN 271. The base number and the viscosity at 100 °C are the same in both: 9.1 mg KOH/g and 14.5 mm²/s.
