You need to give more information.What exactly are you talking about?Was the vehicle run with whatever you are talking about?How long? Is the vehicle running well?If not describe what it is doing?
Sit down and tell us what is going on. Your post makes no sense. Where it sounds like you are at, there is only one diesel. Period. Not really a wrong fuel to put in, unless it was gasoline. But with your post being so vague we have no idea what you are talking about. Did you fill up with red farm fuel? That would be the wrong diesel, but won't hurt anything.
