No need to raise the rear. The engines sump holds very little oil and the drain plug is located towards the rear of the sump, but on the side. The front drain plug drains the reservoir that is mounted high in the engine bay. If you want to drain most of the oil(without removing the hoses to the reservoir or the heat exchanger), then press up on the hose that runs from the reservoir down to the oil pan, after the front drain hole quits draining. There are two hoses, so it's the rearward mounted hose that you want to flex upward. Flex upward between the retaining clip and the oil pan and additional oil will squirt out from the forward drain hole. Wait a minute and repeat. Do this about 6-12 times.
