Application

Heavy-duty diesel engines in trucks, buses and vans from Euro 1 to Euro 3, including those with EGR and/or SCR, for year-round use.

Worth knowing

Engine Oil HD 20W-50 and Engine Oil HDX 20W-50 of the same brand share the viscosity grade but have a different set of codes. The HD has only API CG-4 and ACEA E2, and of the heavy-duty specifications it claims MB 228.1, MAN M 271, Volvo VDS, Renault Trucks RD and MTU Oil Category 1. MB 228.3, Volvo VDS-3 and MAN M 3275 are not in its list, and its base number is lower: 8.6 mg KOH/g against 11.3.

Engine Oil HDX 20W-50 lists MB 228.3 only in brackets after DTFR 15B110. Under this number Daimler Truck keeps the same specification, as the table matching MB 228 and DTFR numbers in the truck and bus oil article shows. The HDX adds ACEA E7, API CI-4 and Deutz DQC-III and has a higher sulphated ash, 1.5 %, while Mack EO-M and MB 228.1 are not named among its codes. In the D-MX IV data sheet all the codes, API classes included, appear under the word “exceeds”; the same sheet gives a cold-cranking viscosity of 5,580 mPa·s at -15 °C.
