Viscosity

Understanding Oil Viscosity Viscosity is the measure of a fluid’s resistance to flow. _by David Hilgendorf|January 17, 2023 The physical properties of lubricants are measured by characteristics like viscosity, shear stability, high- and low-temperature performance, water resistance and volatility. Lubrication science seeks to optimize a lubricant’s performance by managing these properties using different base oils […]

When you see a Low-viscosity Number – Don’t be Alarmed Michael Meuli | VICE PRESIDENT, TECHNICAL DEVELOPMENT As motor oil viscosity continues to decrease, base oil and additive quality become more important. Despite uncertainty surrounding future CAFÉ standards, fuel economy remains the biggest driver of innovation in the auto industry. One strategy for increasing fuel […]

oil weight

What Happens if I Use the Wrong Weight (Viscosity) of Oil? John Baker|Jan 31, 2018 11:19 AM It depends on how your engine is built and how it reacts to the specific viscosity of oil you use. That’s pretty nebulous, so here are some examples. Josh buys a new car that requires 0W-20 motor oil. […]

Understanding Viscosity - Many mis-understandings

Lubricant Viscosity Explained Ed Newman|May 24, 2017 8:30 AM A lubricant’s viscosity and how it changes under different temperatures and operating conditions is one of the most important properties that determines lubricant performance and protection. Viscosity can be viewed in two ways: • Kinematic viscosity • Dynamic (or absolute) viscosity Kinematic viscosity is defined by […]
