When it comes to some things about Enviromental protection.. i'm a little paranoid. I like to Recycle, reduce as much as possible.. keeping the car well maintained for lower emission etc.. I was so sad to see hundreds of emtpy oil bottles in the trash when I was at the Naval Auto Hobby shop.. sure they recycle the Oil filters and the oil.. but the bottles(in which theres oil still left in every single bottles) goes to the landfills.) What do you guys do with them? or do you just carelessly throw them away?
