How does oil viscosity come from? The main reason is the size of the oil molecules. The larger the molecules are, the thicker the oil is; on the contrary, the smaller the oil is, the thinner it is. But mineral oil can't control the molecular size, because it's extracted from crude oil. The size of the molecule is determined by nature. Moreover, it's mixed with various sizes. Synthetic oil is different. It's a lubricating oil produced by human beings. The molecular size can be specially made according to human needs.

SH112C automatic kinematic viscometer (Pinstar): ASTM D445, can measure transparent and opaque liquids to the same accuracy, including the kinematic viscosity of crude oil, light and heavy fuel oil, lubricating oil, additives, silicone oil. It is also suitable for measuring the kinematic viscosity of samples with high wax content or samples containing insoluble components at room temperature. Fully automatic ,constant temperature, viscosity testing, cleaning, and drying viscometer, no random operation is required. After the operator sets out, the operator can leave the site and the instrument can automatically complete all tasks.
