Motor oil is the verve of any automobile. It keeps the components of a car lubricated and reduces heat and friction. The result of using wrong motor oil in the car can vary from annoying to pernicious. Your vehicle will become noisy, and won’t perform fuel-efficiently with the wrong oil. Thus, it is always recommended to use motor oil specified in the owner’s manual. Brand of the engine oil matters litter but the viscosity grade matters a lot. So, being a motorist, you must have clarity of everything while picking the oil for your car.
