It took a lot of enquiring, but I finally nailed the process to dispose of used oil in Hawaii. Seems you get one of these boxes full of fluffy stuff (see pic), pour in your oil, and presto, a no messy liquid in the dumpster way of disposal. The kicker is that the box has the Hawaii recycle logo, and references environmental friendliness. No fiddling around with collection and reprocessing of oil out here. I wonder how many boxes the minute-lube shops get through a week!
