Will old engine oil burn in boiler if diulted?

Question

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.

It was somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Tony saying something like:

Filter it well and add it to the heating oil at a 10% rate. You can find

5 micron filter blanket material if you look in Yellow Pages. I'm currently running my oil furnace on waste oil, veg oil, biodiesel and heating oil as the mood suits.

Yes, it seems to burn fine!

My central heating system uses a Bentone burner...normally burning kerosene.

I have a separate oil drum that I chuck the filtered used engine oil into and then dilute with kerosene....about 20% oil/80% kerosene.

When the drum is full I connect it to the burner instead of the main tank feed.....it runs the system for quite a few weeks.

I have never had a blocked nozzle in all the time I have done this. I have found that you get a better burn if the air feed and injector pump pressure are increased, there is never any smoke or nasty smells.

HTH.
