I just recently bought a car (2000 z28 w/ 100k miles) and decided to switch it over to Moble 1 5w-30 synthetic. When I bought it, it didn't burn any oil. I believe that the previous owner was using regular oil. I have noticed that it burns oil badly now by the smoke that comes out of the exhaust when it starts up and when I give it some gas. If I were to switch back to regular Maxlife 10w-30, would this levitate the leak. I was told that when I added the Moble 1 synthetic, that it might have cleaned some of the clogged areas which might be causing it to burn. I am new at cars and any opinions are greatly appreciated.
