As long as you're under warranty-it would be better to stick to a Mercedes spec 229.51 oil-unfortunately the only ones that are somewhat easy to find are the Mobil 1 ESP (Pep Boys & AV Lube "dot"com), and the Valvoline Synpower MST 5W40 (NAPA should be able to order it). Other diesel HDEOs such as Schaeffer's, Amsoil, regular big 3 diesel oils (Delo 400 LE, Shell Rotella, Mobil Delvac 1300), and pretty much any easy to find diesel oil have TOO MUCH sulfated ash (over 0.8%) and are NOT RECOMMENDED for use with the DPF emissions system. There are some Schaeffer's fans on here that are pushing it for the Sprinter for some bizarre reason-Schaeffer makes some awesome oils, but in the Sprinter-well, if you have DPF trouble down the road-don't blame me!
