Just found out the gentleman that used to come take some of my waste oil has entered hospice. He had me set up 5 gallon drums and asked me to only put oil, ATF and a little bit of fuel (if some got in after a fuel filter change, for example). He would then have a siphon pump that left the bottom few inches in the drums, or maybe a foot? I think he used it for his tractors and heating his barn. He was not a talker haha. But if anyone wants something similar let me know. My zip is 08827.
