Thanks for your input on oil burning. This summer, when I have more time on my hands, I will build my waste oil purifing/ preheating refinery. With this info I can cut my electrical operating costs in half. One thing i notice with my 6/1 is when I start it in the morning the gen head is putting out 57- 58 hz, when fully warmed up, it is about 60- 60.5 hz. With your micro processor controls, do you have a throttle solenoid for rack position?  What brand of controller do you use? and cost? Thanks for all of your replies. Has anyone heard of, or is running an ONEAC POWER CONDITIONER
