Does Parking Reverse on a incline driveway affects your car Engine, compared to Parking regularly on a inclined driveway?
If you use Synthetic oil in the engine, then no. Synthetic engine oil leaves a coat of oil on everything so it has lubrication on initial start up. If you where to use regular oil and parked backward on the incline the oil in the oil pan would not be as accessible to the oil pick up tube. The oil would be more accessible if the car where parked forward on the incline.
