Product Description

Mobil Delvac Modern™ 10W-40 Full Protection 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).Mobil Delvac Modern™ 10W-40 Full Protection will also deliver the same exceptional performance in older conventional engines. It meets or exceeds the requirements of the API CJ-4, CI-4 PLUS, CI-4 and CH-4 service categories.


Mobil Delvac Modern™ 10W-40 Full Protection 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.


Features and Benefits

Mobil Delvac Modern™ 10W-40 Full Protection is formulated with optimized base oil and additive technology to deliver cutting-edge performance in both new and older engines. In addition to assuring enhanced control of oil thickening due to soot build-up and improved TBN retention for long drain intervals, Mobil Delvac Modern™ 10W-40 Full Protection advanced technology also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.



Advantages and Potential Benefits

Enhanced soot-viscosity control

Greater engine efficiency, long engine life and long oil life

Outstanding thermal and oxidative stability

Reduced low temperature sludge build-up and high temperature deposits

Improved oil consumption control

Lower oil costs due to less make-up oil during operation

Improved TBN reserves

Improved corrosion protection and extended drain intervals

Stay-in-grade shear stability

Maintains viscosity in severe, high temperature service for greater wear protection and long engine life

Enhanced low temperature pumpability

Faster oil flow and reduced wear during engine start-up in low temperatures

Outstanding resistance to corrosive and abrasive wear

Long life of critical wear surfaces

Component compatibility

Long gasket, seal, and after treatment (DPF and DOC) life



Recommended by ExxonMobil for use in:

•Heavy duty diesel engines including Euro V/VI or China V/VI modern low emissions vehicles(1), utilizing technologies such as Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR), Continuously Regenerating Traps (CRT), Diesel Oxidation Catalysts (DOC) and Exhaust Gas Recirculation (EGR)

•High-performance diesel applications including turbo-charged designs featuring EGR Technology and diesel applications using older, naturally aspirated conventional designs.

•On-highway heavy-duty trucking and off-highway including: construction, mining, quarrying, and agriculture.

•On-highway applications operating in both high speed/high load and short haul pick-up/delivery.

•Off-highway applications operating in severe low speed/heavy load conditions

•High performance gasoline engines and mixed fleet operations.
