I've heard of people filtering their used crankcase oil and adding to their #2 HHO tank, with no problems. Sounds like a win-win to me.
only works with Dino oil ( not the synthetic stuff ... synth has a much higher flash point and won't burn very well ) ....
hot water tanks don't go for a blue flame ( more towards the yellow ) and carbon up the ignition rods after a bit ...
