To do what?Change it?The easiest way(though not 100%) is with an evacuator pump.Alot of lube places will change it for real cheap,like 20-30 bucks including non synthetic fliud.Just make sure you shop around and don´t get screwed.Oh and prefferably watch them do it to make sure it´s actually done.There was a guy at one shop I worked for that would charge for it when people brought newer cars in at the recommended mileage, and he would crack the box dip a finger and if it was clean and full he´d close it up and charge the customer $30 because he knew that most people have no clue and don´t bother checking for themselves.
