Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers.[citation needed]. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents). It also neutralizes acids that originate from fuel and from oxidation of the lubricant (detergents), improves sealing of piston rings, and cools the engine by carrying heat away from moving parts.

In addition to the aforementioned basic constituents, almost all lubricating oils contain corrosion and oxidation inhibitors. Motor oil may be composed of only a lubricant base stock in the case of non-detergent oil, or a lubricant base stock plus additives to improve the oil's detergency, extreme pressure performance, and ability to inhibit corrosion of engine parts.

Automatic Filling machines for the motor oil or lubricant oil business is same as filling any other liquid type product .because automatic filling machine use volumetric filler .that way can fill any liquid or semi viscosity or high viscosity product Depending on the viscous of the customer’s production, normally piston filling way is widely used. And control by servo motor is most popular way .because it fill very precisely and fast .

Bottlinglife customize different filling machine for different product

Our multiple filling heads filling machine is specially made for all high and low viscosity materials, such as honey peanut butter,tomato sauce, soy sauce, medical alcohol, juice ,oil, milk, water etc. The machine adopts piston pump for filling materials. By adjusting the filling time by touch screen, it can fill all of the bottles in one filling machine, with quick speed and high precision.
