I have several gallons of old engine oil and wondered if it will successfully burn in a central heating boiler if mixed with heating oil? What dilution would you recommend and have any of you tried it?
The visible lumpy s**te would be decanted off first but is the remainder likely to block the injector? With the price of heating oil what it is and the inconvenience of disposing of it any other way out here in the sticks, I would like to give it a go but the wealth of experience on this group would be better tapped before I do it rather than afterwards.
TIA.
