Burning waste oil is relatively easy. Preheat your oil, run it through a burner. Preheat temperature is critical, burning a large enough volume is also very helpful. By that I mean, you want to burn at least 7-8 gallons per hour through a normal oil burner gun with just one nozzle. If you try to go an y smaller, even with filtering, you end up with plugged nozzles all the time. Larrger nozzles with the screen pulled off of them work fine. We used to burn 12 gallons per hour with no problems. maybe a plugged nozzle every other year. Smaller nozzles will work, but withplugging problems.
