Mobil Engine Oils

Exceptional performance

Mobil has specialised in heavy-duty lubricants for more than 80 years. Year after year, decade after decade, Owner Operators and fleets continue to put their trust in Mobil Delvac, chosen by many of the world’s leading heavy duty equipment manufacturers.

Mobil Delvac 1 LE 5W-30

Mobil Delvac 1 LE 5W-30 is a fully synthetic high performance heavy duty diesel engine oil that, when compared to conventional 15W-40 engine oils, helps towards long engine and emission system life while providing long drain capability and fuel economy potential1 for modern diesel engines, including those fitted with Diesel Particulate Filters (DPF). Mobil Delvac 1 LE 5W-30 utilises state-of-the-art technology to deliver exceptional performance in modern low emission engines. Mobil Delvac 1 LE 5W-30 is recommended for use in a range of heavy-duty applications and operating environments found in the on-road transport and off-road mining, construction, and agricultural industries.

The performance of Mobil Delvac 1 LE 5W-30 is the result of development work with major equipment builders and application of the latest lubrication technology. This product simultaneously meets MB-Approval 228.51 and MB-Approval 228.5 requirements in a 5W-30 viscosity grade.

1 Fuel economy potential is dependent on vehicle/equipment type, outside temperature, driving conditions and your current fluid viscosity.

Features and Benefits
High output, low emission engines significantly increase demands on engine lubricants. Tighter engine design reduces oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Thermal stresses on the lubricant are increased with the use of inter-coolers and turbochargers. Higher fuel injection and cylinder pressures and retarded timing improve burn efficiency, but also increase engine temperatures, volatility, and soot loading of the oil. The advanced technology in Mobil Delvac 1 LE 5W-30 delivers exceptional performance in these severe conditions and provides protection of exhaust systems fitted with DPF.

Mobil Delvac XHP LE 10W-40

Mobil Delvac XHP LE 10W-40 is synthetic extra high performance diesel engine oil engineered to provide lubrication to modern, high performance, low emissions engines used in severe on-highway applications. This engine oil is designed using the high performance base oils which provide excellent low temperature fluidity, high temperature viscosity retention, volatility control and contribute to potential fuel economy improvement. The new advanced additive system has been expertly engineered to help prolong the life and maintain the efficiency of emission reduction systems such as the Diesel Particulate Filter (DPF). The DPF is used by several truck builders to fulfil emission requirements of Euro IV and Euro V.

Features and Benefits
High output, low emission engines significantly increase demands on engine lubricants. Tighter engine design, use of inter-coolers, and turbochargers increase thermal stresses on the lubricant. Low emission engine technologies such as higher fuel injection pressure, retarded timing and after treatment devices all require improved oil performance in areas such as oxidation stability, soot dispersancy, volatility and compatibility with after treatment devices. The advanced technology in Mobil Delvac XHP LE 10W-40 delivers exceptional performance and protection of exhaust systems fitted with Diesel Particulate Filters (DPF).
Mobil Delvac MX ESP 15W-40 is an extra high performance diesel engine oil that helps extend engine life in the most severe on and off-highway applications while delivering outstanding performance in modern, high-output, low-emission engines including those with Exhaust Gas Recirculation (EGR) and Aftertreatment Systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs). Fully backwards compatible, Mobil Delvac MX ESP 15W-40 will also deliver the same exceptional performance in older conventional engines. As a result, it meets or exceeds the requirements of the API CJ-4, CI-4 PLUS and CH-4 service categories as well as key Original Equipment Manufacturer (OEM) requirements.

Mobil Delvac MX ESP 15w-40

Mobil Delvac MX ESP 15W-40 is the result of extensive cooperative development work with major OEMs and is recommended by ExxonMobil for use in a wide range of heavy duty applications and operating environments found in the trucking, mining, construction, quarrying, and agricultural industries. This product provides outstanding protection in the most demanding diesel engines of Caterpillar, Cummins, Detroit Diesel, Deutz, Mack, Mercedes Benz, Renault, Navistar, Volvo, and others. Mobil Delvac MX ESP 15W-40 also meets or exceeds the requirements of the API SM / SL specifications for gasoline engines and mixed fleets.

Features and Benefits
Mobil Delvac MX ESP 15W-40 is formulated with Trimer additive technology and a mixed detergent system to deliver cutting-edge performance in both new and older engines. In addition to assuring excellent control of oil thickening due to soot build-up and outstanding TBN retention for long drain intervals, Mobil Delvac ESP 15W-40’s advanced technology also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.

Mobil Delvac MX 15w-40

Mobil Delvac MX 15W-40 is high performance diesel engine oil that helps extend engine life in the most severe on and off highway applications. The advanced chemistry of these products delivers exceptional performance in both modern, high-output engines including those with Exhaust Gas Recirculation (EGR), as well as older engines operating on either low or high sulphur fuels. As a result, Mobil Delvac MX 15W-40 meets or exceeds the API CI-4 PLUS service category and ACEA E7 industry specifications.

Mobil Delvac MX 15W-40 is recommended by ExxonMobil for use in a wide range of heavy duty applications and operating environments found in the trucking, mining, construction, quarrying, marine and agricultural industries. These products will provide outstanding protection in the most demanding diesel engines of Caterpillar, Cummins, Detroit Diesel, Mack, Mercedes Benz, Navistar, Volvo, and others. Mobil Delvac MX 15W-40 also meets or exceeds the API SL specification for gasoline engines and mixed fleets.

The outstanding performance reserve of Mobil Delvac MX 15W-40 is the result of extensive cooperative development work with major Original Equipment Manufacturers (OEMs) and advanced additive chemistry with patented Trimer technology. These enhancements assure excellent control of oil thickening due to soot build-up and exposure to higher temperatures and provide outstanding resistance to oxidation, corrosion, wear, and high temperature deposits.

Features and Benefits
Modern high output diesel engines including those using EGR technology generate higher levels of soot and run at higher temperatures than older, naturally aspirated engines, which significantly increases the demands on engine lubricants. These engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Top piston rings are located higher on the piston bringing the oil film closer to the combustion chamber where higher temperatures increase thermal stress on the lubricant.  Higher fuel injector pressure and retarded timing improve exhaust emission control, but also increase engine temperatures and increase soot loads, including those engines operating with EGR.
