Meet the main additives of lubricants by chemical family — sulfonates, salicylates, succinimides and dithiophosphates — and how structure drives function. Read more

How additives serve every oil industry stage — drilling fluids and flow assurance upstream, refinery and fuel chemistry downstream — with the key chemistries. Read more

Viscosity improver polymers work through coil expansion, entanglement, and shear thinning. Understand hydrodynamic volume, molecular weight, and shear stability in lubricants. Read more

Viscosity improver oil additives must coexist with detergents, dispersants, ZDDP, and antioxidants. Learn the compatibility rules of building a complete engine oil package. Read more

A viscosity improver for oil is what makes engine oil multigrade: 5W-30 and 10W-40 pass both cold cranking and hot film tests. Learn how it works and how to dose it. Read more

A viscosity improver for lubricants must match its application: engine oil, gear oil, hydraulic fluid, or ATF. Compare polymer chemistry and SSI needs by oil type here. Read more

Viscosity improver additives come in four chemistries: OCP, PMA, styrene copolymers, and PIB. Compare them by application to choose the right one for engine, ATF, gear, and hydraulic oils. Read more

A viscosity improver additive is the polymer component used to build multigrade oils. Learn how to dose it, calculate treat rates, and blend it without problems. Read more

A VI polymer is a high-molecular-weight polymer that controls lubricant viscosity-temperature behavior. Compare OCP, PIB, and PMA architectures for your formulation. Read more
