I most often run it onto a couple of 2X12's which allow me to work myself under for inspection without raising it up so much that some of the oil gets caught in the rear of the upper portion of the oil pan. But, you can drain the oil by simply sliding a drain pan underneath without raising the car and reach under to take out the drain plug. You will have to lay on your side to do this, so put on your old clothes first.
160 degrees F is not operating temperature for your oil. Full operating temperature is a little over 200. You will need to drive the car about 17 miles to get the oil to full temp. The coolant temp will come up in just a few miles, but oil temp lags by quite a bit.
