I am pretty sure the difference between the low level line and the full line on the dip stick is pretty much one quart. If you are not even up to the minimum line, I would expect that you will need at least one full quart. Maybe more depending on how low it actually is. Add it at the store so you can be sure you have enough before you leave. The best time to check the level is about five minutes after turning off a warm engine, so drive to the store, go buy the oil and by the time you get back to the parking lot it will be about perfect.
