Mobil Delvac Modern 5W-20 Advanced Protection
Synthetic-technology fuel-economy oil for DPF trucks and buses, MAN M 3977, Scania LDF-5
SAE 5W-20
Mobil Delvac XHP Ultra LE MN9 5W-20 is an extra high performance diesel engine oil engineered to provide outstanding protection and fuel economy potential in modern, high performance, low emissions engines used in severe on-highway applications. It is specifically designed to meet the latest MAN M 3977 requirements for modern diesel engines equipped with Diesel Particulate Filters (DPF), formulated with advanced synthetic technology base oils for excellent low-temperature fluidity, high-temperature viscosity retention and volatility control, and an advanced additive system engineered to help prolong DPF life and efficiency. ExxonMobil recommends it for the latest generation of MAN trucks and buses requiring MAN M 3977 approved lubricants, for on-highway light and heavy-duty trucking, and for modern heavy-duty engines equipped with DPF in line with owner's manual recommendations; it may not be used in engines requiring older or other oil specifications. Key benefits include excellent protection against oil thickening, oil degradation, high-temperature deposits and sludge build-up, excellent protection against wear, scuffing, bore polishing and corrosion, excellent low-temperature fluidity for cold-climate operation and start-up wear protection, advanced low-ash componentry supporting DPF durability, and advanced formulation viscometrics with potential fuel economy benefits alongside stay-in-grade shear stability and very low volatility. Mobil Delvac XHP Ultra LE MN9 5W-20 carries the MAN M 3977 builder approval; its key properties include SAE 5W-20 grade, viscosity index 147 and total base number 10 mgKOH/g (ASTM D2896).
