Should I have to refill my oil every month? Should smoke be coming from the exhaust?

Hello, most automakers suggest it's possible to consume a quart of oil in 1,000 miles, or maybe 1,500 miles. You'll have to see if that's within the criteria of your driving habits. Regardless, if you have to add oil - you have two choices. First, stay on top of it and make sure it's never low. Check it every time you fuel. Second - invest in diagnostic testing and what will likely be expensive engine repairs. Your threshold of pain is the limit here - how much oil consumption is too much?
