Here we go again!! I live in a very hilly area and almost always park my car on a pretty steep incline overnight. Is it best to park with the front facing uphill or downhill?? I am not worried about the car slipping more about the fluids; such as oil. I know that the morning startup is what puts the most wear and tear on the engine. If the car is parked on a hill then isn't the oil collecting unevenly???
