I just wasn't sure if the Sprinter OM642, which has a DPF, but NOT the SCR/Blutech (urea) system, could use the 228.31, which includes many American HDEOs such as Valvoline PBX-but the 229.51 will be difficult to come by (unless from a dealer, or distributor) in a quick lube location. Looks like I'm going to have to try to get the Valvoline Instant OC guy by me to get the Synpower 5W40 MST, thanks for the info.
