Lubricating Oil and Additive Testing

Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processing parts. Lubricating oil mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

Lubricating oil and additive testing can evaluate the quality of oil products, help enterprises avoid procurement risks, strictly control the quality of new oil into storage, and ensure the safety of equipment lubrication. The test report of lubricating oil in use can put forward the corresponding treatment and solution measures according to the lubrication and wear status of the equipment, which provides the decision-making basis for enterprise equipment management personnel to carry out lubrication management and maintenance, and avoid serious lubrication malfunction and mechanical failure.

STEMart provides comprehensive lubricating oil and additive testing services to provide customers with quality inspection of purchased and in-stock lubricant products, and monitor oil degradation trends and equipment wear status to prevent unexpected shutdowns and avoid major failures.
