Mobil Delvac Legend 15W-40 Heavy Duty
Synthetic-blend heavy-duty diesel oil for on- and off-highway service, ACEA E3, API CH-4
SAE 15W-40
Mobil Delvac™ Super 1400 15W-40 is a high performance diesel engine oil that protects diesel engines operating under severe service conditions, for both on- and off-highway applications. ExxonMobil recommends it across a wide range of heavy-duty operating environments in trucking, mining, construction, quarrying and agricultural industries, covering naturally aspirated and turbo-charged diesel equipment from European, Japanese and American manufacturers. Its thermal and oxidation stability helps control sludge build-up and deposits, while its TBN reserve helps control deposits over the drain interval. Stay-in-grade shear stability helps reduce oil consumption and provide wear protection, and its excellent detergency/dispersancy helps protect and keep engines clean. Component compatibility supports long gasket and seal life. SAE 15W-40, Mobil Delvac Super 1400 15W-40 carries MTU Oil Category 2 approval and is recommended for applications requiring ACEA B2, ACEA E3, API CF, API CF-4, API CG-4, API SH, MAN M 3275-1, RENAULT TRUCKS RD and RD-2, and VOLVO VDS-2, and meets or exceeds API CH-4 and API SJ.
MTU oil quality category 2: higher-quality monograde and multigrade oils for MTU diesel engines, without an ash cap.
ACEA B2 oil sequence
ACEA's sequence for light-duty diesel engines. An earlier sequence, no longer on ACEA's current list; it remains the level specified for the engines of its era.Source
ACEA E3 oil sequence
ACEA's sequence for heavy-duty diesel engines of the Euro I–III era. An earlier sequence, no longer on ACEA's current list; it remains the level specified for the engines of its era.Source
Diesel engine oil, API CF performance level
API's service category for indirect-injection diesel engines, tolerant of higher-sulphur fuel. An earlier category in the API service classification, written for the engines of its era; it still appears on datasheets alongside the current categories.Source
Diesel engine oil, API CF-4 performance level
API's service category for high-speed four-stroke diesel engines, of the generation preceding the emissions standards. An earlier category in the API service classification, written for the engines of its era; it still appears on datasheets alongside the current categories.Source
Diesel engine oil, API CG-4 performance level
API's service category for heavy-duty diesel engines, written for fuel below 0.5 % sulphur. An earlier category in the API service classification, written for the engines of its era; it still appears on datasheets alongside the current categories.Source
Petrol engine oil, API SH performance level
API's service category for spark-ignition engines, of the early 1990s. An earlier category in the API service classification, written for the engines of its era; it still appears on datasheets alongside the current categories.Source
MAN M 3275-1 — truck engine oil
MAN's specification for medium-drain truck engine oils at the ACEA E7 level, without a low-ash requirement.
Renault Trucks RD-2 — engine oil (obsolete)
Renault Trucks' old engine oil specification, predating the RLD series. It appears only on datasheets for older fleets.
Volvo VDS-2 — Volvo diesel engine oil
The second generation of the Volvo Drain Specification, for heavy-duty diesel engines without aftertreatment. Withdrawn, but still quoted for older fleets.
Diesel engine oil, API CH-4 performance level
API's service category for compression-ignition engines. Current category.Source
Petrol engine oil, API SJ performance level
API's service category for spark-ignition engines. Current category.Source
