And that's the part that scares me about Dodge and the Sprinters-if they can't figure out simple problems, like diesel fuel mixed with gasoline, and the VP44 failure on my '02 Cummins, if you have a DPF problem (not saying that you will) under warranty, they will be looking for anything they can to void your warranty (as they did on my VP44, but the pump wire had never been tapped/no programmer). BTW, used Rotella T 15W40 in my co.'s 6.0 for probably the first 85K of it's life, other than hard/romping/smoky cold starts, worked great!
