Mobil Delvac Modern 5W-30 Fuel Efficient Plus V1

Extra High Performance Diesel Engine Oil

Mobil Delvac Modern 5W-30 Fuel Efficient Plus V1

Mobil Delvac Modern 5W-30 Fuel Efficient Plus V1 is an extra high performance advanced synthetic technology diesel engine oil engineered to provide outstanding protection and fuel economy potential(1) in modern, high performance, low emission engines used in severe on-highway applications.

Mobil Delvac Modern 5W-30 Fuel Efficient Plus V1 is formulated with high quality base oils which provide excellent low temperature fluidity, high temperature viscosity retention, volatility control. The base oils, the additive system, and the lowered film viscosity (HT/HS) contribute to fuel economy improvement potential. The 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).

Mobil Delvac Modern 5W-30 Fuel Efficient Plus V1 is specifically designed to meet the latest Volvo, Daimler, Detroit, Mack, Renault, and Cummins requirements for their newest diesel engines.

(1)The fuel economy potential is based on experience of comparing the 5W-30 with a 10W-40 & 15W-40

Features and Benefits

High output, low emission diesel engines significantly increase demands on engine lubricants. Tighter engine design, use of inter-coolers, and turbochargers increase mechanical and thermal stresses on the lubricant. Low emission engine technologies such as higher fuel injection pressure together with 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 Modern 5W-30 Fuel Efficient Plus v1 delivers exceptional performance and protection of exhaust systems fitted with Diesel Particulate Filters. The key benefits include:



Advantages and Potential Benefits

Excellent protection against oil thickening, oil degradation, high temperature deposits, and sludge build-up

Contributes to long oil life consistent with OEM recommended Oil Drain Intervals (ODI)

Helps prevent ring sticking for better engine protection and efficiency

Excellent protection against wear, scuffing, bore polishing, and corrosion

Helps control wear in heavy duty operation, promoting long engine life

Excellent low temperature fluidity

Contributes to excellent oil pumpability and circulation allowing operation in cold climate regions. Helps protect against wear during cold engine start-up

Advanced "Low Ash" componentry

Helps improve efficiency and extend durability of emission exhaust systems fitted with Diesel Particulate Filters (DPF)

Advanced formulation viscometrics

. SAE 5W-30

. Stay-in-grade shear stability

. Very low volatility

Potentially helps to reduce fuel consumption over higher viscosity grade engine oils without compromising engine durability (potential fuel economy depending on vehicle type and driving conditions).

Helps to control viscosity breakdown and oil consumption under heavy duty, high temperature operating conditions
