Apparatus and method for reclaiming waste oil for use as fuel for a diesel engine

An apparatus for reclaiming waste oil for use as fuel for a diesel engine, said apparatus comprising:

• a) a mixing tank;
• b) a source of waste oil;
• c) a source of light fuel oil;
• d) a first pump adapted to supply waste oil from said source of waste oil to said mixing tank at a first flow rate;
• e) a second pump adapted to supply light fuel oil from said source of fight fuel oil to said mixing tank at a second flow rate proportional to said first flow rate, the light fuel oil blending with the waste oil in said mixing tank to form an oil-fuel mixture;
• f) a heating unit installed in said mixing tank for heating the oil-fuel mixture;
• g) a fuel line connectable to a diesel engine for communicating the heated oil-fuel mixture from said mixing tank to the diesel engine;
• and
• h) a three-way start valve controlling flow through said fuel fine, said start valve further being in communication with a source of light fuel oil and adapted to selectively provide only light fuel oil to the diesel engine during start-up so as to facilitate starting of the diesel engine, said start valve being further adapted to selectively supply the heated oil-fuel mixture to the diesel engine after the diesel engine is started.
