Dust, oil leaks, old leaves, sand and other contaminants accumulate on the engine. All these can clog the radiator, engine air filters, and cabin filter. Consequently, this can lead to oil spots on your driveway, an unpleasant smell inside the car, corrosion, lackluster engine performance, and poor gas mileage. Worse, it can lead to your vehicle malfunctioning. This is where engine detailing comes into play regardless of the kind of vehicle in question – car, van, or truck. Engine detailing is, by no doubt, important and you should do it from time to time.
