Considering how important it is to recycle oil, not only for environmental reasons but for oil dependency issues also, why do so many auto parts places act so reluctant to take used oil? I live in an area where there are only three places to buy oil: Advanced Auto, Autozone & Walmart. First off, my Walmart doesn't take back used oil because they don't have an oil-change/auto service facility. Considering I buy most of my oil products there because they beat the auto chains on price, that sucks. However, I don't buy my filters at Walmart...I buy them at the other two places. Thus, after an oil change, I take my used oil there and buy a new filter for my next service. What kills me is that neither place wants to take oil back...they make a major production out of it. It's not like I'm sitting an oily milk jug on the counter and walking off. Rather, I just want to pour the stuff into their recycling container myself and be on my way. But it's always this major production...sighs, asking me if I bought the oil there, telling me that they don't dispose of used filters, etc. Now I understand that they can't just have a big container out back since people could put all kinds of crap in there. However, there has to be a better way to encourage people to do the right thing with their used oil. Does anybody else catch any flack when they try to recycle their oil? Do the major chains accept used oil voluntarily or is it a state/federal mandate? I wouldn't mind paying a small charge for someone to accept this oil, but only if I had an assurance that it was being disposed of properly. Last time I was at Advanced Auto, the kid I gave my oil fitler to launched it over the fence surrounding their dumpsters...which really ****** me off.
