Is GF-6A oil low ash?
1 Answers
GF-6A oil is low ash. Definition of low ash oil: It is a specially designed oil for vehicles equipped with exhaust gas purification devices. Causes of low ash oil: It refers to the incombustible metal salts and metal oxides (such as metal sulfates, etc.) remaining after the oil is completely burned under specified conditions, usually caused by additives in the oil. As the ash content increases, the engine displacement gradually decreases, but the power does not decrease, which means the "power per liter" continues to increase, thereby increasing the pressure on the engine.
