I have been trying to reduce the amount of waste oil I have to take to the recycling depot, so I decided to burn the waste oil I accumulate to heat my shop. Initially I was going to use a modern oil furnace, but I found an old 1940's Duo-Therm on Craigslist and bought that instead. After about 20 hours of cleaning and testing, I now have it burning a 50/50 mix of diesel and waste motor oil. It's been heating my shop now for a week and I love this old thing. It's burning about 2-3 quarts an hour and heats my shop up to 65 degrees. I no longer have to take my oil or filters to the recyclers as this furnace burns both. Here's some video's and pictures:
