I have had to replace the filter and nozzle twice in the last 4 months. The service man says my oil tank has sludge in it. A friend gave me a can of something he bought at an oil burner supply house that is suppose to break up sludge and keep the filter and nozzle from becoming clogged. I was wondering if I put this stuff in my tank could it break up the sludge and possible make things worse? Do these chemicals work?
