Description

Mobil Delvac Ultra 5W-40 Ultimate Protection V1 is a fully synthetic, low-ash oil for high-output diesels with any exhaust after-treatment system, designed for extended drain intervals.

Official approvals: DDC DFS 93K218, DDC DFS 93K222, Cummins CES 20081, Cummins CES 20086, DTFR 15C100. Classes: API CK-4, CJ-4, CI-4 Plus, CI-4, CH-4, SN, SM, SL, ACEA E7, E11, JASO DH-2; ExxonMobil recommends it where ACEA E9 is specified. Without formal approval, it meets CAT ECF-3 and Isuzu DEO.

Sulphated ash 1 %, base number 12 mg KOH/g, HTHS 3.8 mPa·s, 13.8 mm²/s at 100 °C, pour point -48 °C.

Application

Current and older high-output diesels in trucks, buses and off-highway machinery with any exhaust after-treatment system, on extended drain intervals; also petrol engines in mixed fleets.

Worth knowing

The Isuzu DEO line appears both here and in the data sheet of Mobil Delvac Ultra 5W-40 Ultimate Defense, but the notes in brackets are opposite: “w/ DPD” here, “w/o DPD” there, that is, machines with and without a diesel particulate filter (DPD). In both cases it is compliance, not approval. The Cummins codes in the two data sheets do not overlap either: CES 20081 and 20086 for this oil, CES 20076, 20077 and 20078 for the Ultimate Defense, although the line and SAE grade are shared.

This data sheet lists no MAN codes. No Mobil 5W-40 oil in the catalogue has the M 3677 approval; it is found, for example, in Mobil Delvac Ultra 5W-30 Ultimate Protection V2, but that is a different SAE grade, and engine documentation specifies the code together with the viscosity. The petrol classes here are limited to API SN, SM and SL, and ExxonMobil’s mention of mixed fleets does not settle whether such a class suits a particular vehicle; see which cars API SM still suits today.
