Hey, not sure which forum this should have one in, but whatever. I have a 2010 cobalt 2lt. 2.2. I have 27600k on it and I just changed my oil today to Mobil super 5000. I love to baby my car and I don't drive like an a$$ hole. Sometimes, but pretty rarely. Would changing to synthetic be a wise choice? I want my car to be as efficient and long lasting as possible. If so, am I able to put it in when it comes time to change the oil?(32k miles). I know my car doesn't require synthetic, but like I said, I want to do anything I can to make it more efficient, unless switching would be a waste. Is it wise to switch to synthetic or should I just keep using conventional? This is the first time I changed the oil since I got the car so idk what the previous owners were using. Any help would be appreciated.
