 We bought this car about 2 months ago with 4200 miles on it. It was a dealership beater car for them. The car now has 8500 miles on it and it's now in the shop having the engine replaced. As soon as we got the car, I realized the number of RPM the engine turned so I chose to switch to full synthetic Mobil1 5/30. After 2900 miles, my roommate came home and explained to me the car was ticking. I pulled the oil stick to reveal a clean stick, NO oil. Now, after 2 weeks and a new engine, I'm still in a rental car because they can't get the new engine to run right either. Hope its fixed soon. Awesome gas mileage and comfortable. PLEASE LASSIE COME HOME. Hope no more problems after this!
