Eni i-Base 15W-40

Description

Eni i-Base 15W-40 is a multigrade engine oil from the i-Base line for petrol and diesel engines in cars and commercial vehicles that spend much of their time on the motorway or in stop-and-go town driving. Its detergent and dispersant additives keep varnish and sludge in check.

The oil is rated API SM and API CF. It holds no official manufacturer approvals; the maker states that it meets the requirements of MB 229.1, VW 501.01 and VW 505.00.

Typical figures: kinematic viscosity 14.5 mm²/s at 100 °C, viscosity index 140, pour point -27 °C, base number 10.1 mg KOH/g.

Application

Petrol and diesel engines in cars and commercial vehicles under heavy use: long motorway runs, stop-and-go city traffic and taxi work.

Worth knowing

In the Eni data sheet the numbers MB 229.1, VW 501.01 and VW 505.00 appear in the specifications section next to API SM and CF, and in the catalogue they appear in the “Meets the requirements of” row. Such an entry is the oil maker’s own statement, so where the service book demands an oil approved by the carmaker, it does not replace an approval. Status matters more than the mere presence of the number: on the MB 229.1 page most oils in the catalogue carry this code as compliance, not as an approval.

It is easily confused with Eni i-Base professional 15W-40, which has the same viscosity. The professional version is rated API SL and CF, and no Mercedes or VW codes are listed for it; i-Base 15W-40 has the newer petrol class API SM. Typical figures of the two are almost identical (14.5 and 14.4 mm²/s at 100 °C, viscosity index 140), so it is chiefly the list of specifications that tells them apart. Who stands behind each statement on the can, and where to check it, is explained in the article “Approved, meets, recommended: how do you check an oil approval?”.
