	What is the effect, if any of using used cooking oil in a bio diesel mixture if the oil used was used to fry chicken as in a KFC? There is a lot of chicken fat mixed in with the cooking oil.

	It needs to be filtered to remove suspended solids, then chemically treated to convert some of the substances within it. The reactions needed are in the public domain, and information is spread widely over the 'net. Provided one doesn't mind the vehicle smelling like an old fish shop at times then the only things left to overcome are: exposure of some elastomeric materials in the fuel system to biodiesel can cause them to swell and/or perish; the engine needs to be suitable for running 100% home-brew diesel invalidating any manufacturer's warranty over the use of the engine local laws relating to the manufacture and use of home-brew fuel the different waxing temperatures for home-brew versus commercial diesel fuel the safety of the chemical conversion process and equipment how much time is available to the process operator to build the process equipment and carry out the conversion process storage of the reagents and the reaction process products __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	GA. There is absolutely nothing wrong in using used cooking oil to make biodiesel as long as it's done in accordance with the law. Just remember the following preparatory steps: filter the oil to remove fine solid particles that can clog up fuel lines, and heat the oil for some time before processing it to remove water. __________________ If only you knew the power of the Dark Side of the Force

	GA to PWSlack. I would recommend running a mixture of biodiesel and petroleum diesel. In warm weather my current employer runs "B10" - 10% biodiesel, 90% Ultra Low Sulfur Diesel (#2 fuel oil.) In winter they run 10% biodiesel, 40% #2 ULSD, and 50% ultra low sulfur kerosene (#1 fuel oil.) This is acceptable to the vehicle and engine manufacturers we use, and hasn't caused any problems such as fuel "gelling" (actually wax condensing out of the fuel and clogging the fuel filters, but that's another topic.) I strongly suggest checking your vehicle or engine manufacturer's warranty- some may not permit biodiesel blends, or may specify a max percentage of biodiesel. That being said, a biodiesel blend (B5, B10) can actually increase the lubricity of ULSD, which tends to be a bit "dry". So if you have an older diesel engine and are being forced to run ULSD in it, biodiesel can actually help. __________________ ASCII silly question, get a stupid ANSI.
