Base Oil Testing

Base oil is the main component of lubricating oil, accounting for more than 90%, which determines the basic properties of lubricating oil. Base oil can give the lubricating oil the most basic lubrication, cooling, oxidation resistance, corrosion resistance and other properties. The quality of base oil is directly related to the final performance of lubricating oil, so the base oil testing is particularly important.

Base oil testing is mainly to determine the performance, composition and content of each component of the oil. Good base oil testing can help you improve the quality of oil products, increase product value, and develop high-quality and environmentally friendly oil products, thereby promoting product sales and business prosperity.

STEMart provides comprehensive base oil testing services to provide professional technical support for customers to improve oil quality and enhance product value.
