My 2003 GT has sat in my garage for 2 years without being started. I was starting it monthly until the battery died and I kept putting off buying a new one. I am picking up a new battery today and I wanted to get it started. What should I do before starting it and what should I look for once it starts. I think it has a small amount of gas in it and I am planning on putting a couple gallons of fresh gas. I am going to change the oil and I am not sure whether I should do that before or after I start it. Any advice would be appreciated. Thanks.
