I've only owned the car for about 6 months. It burned up the conventional oil that came in the car. So when I changed the oil for the first time, I tried Max Life synthetic blend. It still burned up about 2 quarts (same as the conventional) after only about 2,500 miles. I topped it off and added a can of Restore. I'm going to change the oil again soon and I want to use a synthetic. Would the Walmart full synthetic be good enough? Or should I try PP, M1, etc.? I've even looked into Amsoil and Edge. Thanks for the help!
