I know of several people that are doing this now. My freind that is doing this told me that if you use used motor oil, it is broken down and diluted a little from the fuel getting past the rings enough that you can just mix it in with regular deisel fuel. He started with a 30 percent mix. In the summer months he runs 70 percent. His truck does not some too bad bud it does smell like buring oil. he has a filter set up he uses to filter the used oil. I have started doing the same, when i change the oil in my truck or cars i just pour the waste in my tank. I have not been able to tell a difference at all. I have a new truck with the particalate filter. you are not suposed to do it with those but it has made no difference.
