What's the best oil to use in a 2000 Pontiac Grand AM?

I currently have about 175,000 miles on it and I have been changing the oil every three months. I have to keep adding oil to it about once or twice between changes. I just wat it to continue running smoothly for me until I get out of school and can buy another one. Any suggestions on keeping it in good condition. Thanks
