It is like the all-time-companion that guides you about every single aspect related to your car. It helps you understand what exactly your car needs along with the quantity. Handbuch also counsels you about the type of fuel required for optimum performance and functioning of your car. You may not know but it's important to provide your car with the right type of engine oil. PSI levels of the tires are also mentioned in the Handbuch.
