Just to make sure it's clear, the answers to his original questions are A and A. However, being off by 1/4 or 1/2 quart won't cause a problem, so it's probably more important to be consistent -- don't compare your measurement when cold with your measurement after arriving at the gas station. Remember, too, that your engine (& oil) take much longer to warm up than does the coolant which your dashboard temp gauge monitors. It will probably take 15 or 20 minutes to fully warm up the engine in city traffic. If you just hop in the car and drive 5 minutes to the gas station, you'll have to wait more than a few minutes for the not-warm oil to mostly drip back into the pan.
