They broadly fall into two categories - monograde and multigrade – depending on whether their viscosity changes significantly with temperature or not. The viscosity grade of a multigrade oil is different at high and low temperatures due to additives known as viscosity modifiers. Lubricants are remarkable fluids and essential in modern life.  To have a better running of car engines and gearboxes, the oil and greases should be good. Most of the lubricants are petrol-based. It is necessary to change your oil as per the schedule to avoid contamination of oil. Proper lubrication provides the best protection.
