Hi guys and girls, new here. I was doing some research on black diesel and came across this website. I have been using black diesel for about six months now. I farm and have been using it in all my diesel engines. I started out by using a 80% waste oil to 20% diesel. I found that some diesel engines run differently on it. I have a 986 international tractor that I could probably run straight black diesel on. I have a 575d ford newholland backhoe that does not like it at all. I now run a 50-50 mix. I have processed almost 2500 gallons, and have run a lot of it through a 912 duetz diesel engine that I pump water for sprinklers. It is a 100 hp and has used most of the black diesel. I have a 2004 6.0 ford powerstroke which I ran 50% mix. I purchased this truck in Jan.2012. I did not know these trucks were so fickle. Since I have bought it, it has had to have at least five to ten minutes to warm up until it ran smooth. After that it was great. The first time I put black diesel in it, it runs so much more quite, and it does not need to warm up at all before I take off. I do use Seafoam in my mix to cut down on carbon buildup. I have also saved thousands of dollars. The only draw back is if I get to high of percent of oil, it tends to loose power, which could be do to other problems such as filters. Although I do not seem to change fuel filters any more frequent. I am still experimenting, and it is a very oily dirty job at times. But I am sold on this. It really helps making the engine run more quite. I can also tell a difference when I am filtering the oil in where it comes from. I have one supplier that is a auto repair shop. I get about 500 gallons a month and I have to change my filters less with his oil than some of the farms I get it from. Sometimes it has antifreeze in the oil, but I have welded nipples on 55 gallon barrels about two inches from the bottom. I then have welded a nipple with a valve on bottom of each barrel so that when I leave the oil set for 24 hrs, the water settles to the bottom with the sludge and I filter the rest. I am now working on a centrifuge that I got off an old eruopean tractor called a Zetor that use one for a filter instead of the spin on filters, to take out more of the contaminates before it goes through the filters. I right now I am using a three stage filtering system. I start at 10 microns, and then a 5 micron, and then go down to 1 microns. love the stuff so far.
