WebApr 29, 2024 · HTHS viscosity measures the temporary viscosity loss under these conditions: The lower the measured number, the lower the HTHS viscosity of the oil and the higher the anticipated fuel efficiency benefits. HTHS viscosity is measured in milliPascal.second (mPa.s) but is also commonly referred to in centipoise (cP). Webviscosity, at high shear rates, is much lower than the low shear viscosity measured by kinematic methods. The lowering of HSHT viscosity is due to temporary shear- thinning of polymer-containing multigrade oils. 6.
