    Default Used motor oil fired evaporator?

    Seems like I can't keep up with the wood pile most years and am researching other fuel options.
    Has anyone ever built an oil fired evaporator with a burner that can burn used motor oil? If so, about how much oil do you burn per hour while boiling?

    Varies by location, but there are often rules about burning used motor oil.

    There has been some posts recently about someone that built one burning used vegetable oil from his local restaurants.

    I think this is the post you are referring to. There are also youtube videos of it in action as well if I recall correctly. I might try this on my next build...

    Yeah. I built the used veggie oil burner. I highly recommend to NOT burn used motor oil. It stinks, Way worse for the environment and 1 drop in your pans will ruin your syrup.
    If its home built, non CSA approved rig then go with veggie oil.
