Is the drain plug the fitting on the bottom of the pan that requires a square drive tool? And if it is, is it right hand or left hand thread?

Hi chkraz

I am not so familiar with oil change but I have search a site where you can get some idea about oil change: http://autorepair.about.com/od/regularmaintenance/ss/oil_change_3.htm
Sometimes I read automotive topics like autopartswarehouse (http://autopartswarehouse-1.blogspot.com) to know about car repairs, car care and some car tips. It helps me a lot about knowing the automotive world.
