Just bought a new to me a red 2012 LT1 with RS package. Cruze has 51k miles and came with a K&N intake system (removed because I was tired of the noise). So far loving the car and gas mileage, other than having to take it to the dealer the day after buying for the valve cover replacement that seems normal for a leaky PCV. In Michigan south of Flint and will be doing 120 miles round trip to work shortly. Hence loving the gas mileage. Glad to be on here and already seeing a couple things I'm going to do. 12v outlets hot at all times will be the first.
