Do I need to trade my car in? It's a 2012 gt with 29k miles and under hard acceleration, I have been told, that there is white smoke (oil) from the exhaust. My mods are simple bolt-ons; offroad-x pipe, Jlt intake, Jlt catch can, and 93 lund tune. I pulled my number 8 plug and it appeared to be fine. The plug looked new minus discoloration from heat. pls help:shrug:
