I've never heard of the dip stick oil change method, so I need some opinions please. I discovered it today through the deal HERE on a device that does it. If the deal is dead by the time you see this, there is another one HERE for reference. I then found a basic how-to on the process HERE. The benefit to this, is I don't have to climb under the car. My main question, is can I get to the oil filter without jacking the car up? This is on a Grand Prix GXP, by the way. Any help is greatly appreciated!
