Cars rely on a variety of lubricants to keep their moving parts from becoming expensive glitter, and that’s all down to viscosity, the ability of a material to flow without deforming (known as shear). Lubricants need to be able to flow at different temperatures without becoming too thin to do their job of alleviating friction between surfaces. And as it turns out, there’s an upper limit to viscosity that’s well beyond the weights listed on each bottle of motor oil.
