I understand that lots of folks, for whatever reason, choose to change their own oil. Maybe you just like doing it, or maybe you have farm equipment you service yourself. What do do with that old used oil? Well. I collect it to use to heat my shop with a waste oil furnace, which the EPA accepts as an approved method of recycling. Simply drop off smaller quantities of used motor oil, ATF, hydraulic fluids, or old diesel fuel at the shop or if you have larger quantities, give me a call, and I will arrange to come pick it up.
