Viscosity Testing and Shear Stability Testing
Savant Labs offer test methods for viscosity testing and shear stability testing. We understand the need for the industry to further evaluate the fuel-efficient benefits of engine oils in different operating conditions within an engine. Using the High-Temperature, High Shear Tapered Bearing Simulator Viscometer (HTHS-TBS), Savant Labs have the ability to measure viscosities from 40ºC to as high as 200ºC in addition to the standard HTHS testing at 100ºC and 150ºC. Savant's expertise allows us to measure viscosity at customized shear rates from 1x105 s-1 to 7x105 s-1. With the experience and knowledge of the equipment manufacturer, Tannas Company, a sister company of Savant Labs, we have skills and experience beyond most testing labs in the industry.
Savant Labs’ Founder, Ted Selby, has written numerous technical articles related to viscosity and shear stability which can be found in our technical paper library.
Our expert chemists and technicians have also written overview articles related to viscosity and shear stability listed below.
