Mobil Delvac Legend 15W-40 Heavy Duty is a multigrade, synthetic-blend diesel engine oil that provides protection for diesel engines operating under severe service conditions in both on- and off-highway applications. ExxonMobil recommends it for a wide range of heavy-duty applications and operating environments in trucking, mining, construction, quarrying and agriculture. It is suited to naturally aspirated and turbo-charged diesel equipment from European, Japanese and American manufacturers (in line with owner-manual recommendations), on-highway light and heavy-duty trucking, and off-highway industries. Key benefits include thermal and oxidation stability that helps control sludge build-up and deposits, TBN reserve for deposit control, stay-in-grade shear stability that reduces oil consumption and protects against wear, excellent detergency/dispersancy that keeps engines clean, and component compatibility for long gasket and seal life. The product carries approvals from MTU (Oil Category 2) and DAF (DTFR 15B110), is recommended for ACEA E3/B2, API CF/CF-4/CG-4/SH, Mack EO-M, Volvo VDS-2, MAN M 3275-1, and Renault Trucks RD/RD-2/RLD, while meeting or exceeding API CH-4 and API SJ. It is an SAE 15W-40 grade with viscosity index 137, viscosity 15.2 mm²/s at 100°C, TBN 8 mgKOH/g and pour point -33°C.
