Why does honey flow more slowly than water? Because of the difference in its viscosity. Viscosity is the measure of a fluid’s resistance to flow. Water, for example, flows much faster than honey or maple syrup (if you prefer that in your morning coffee) when poured from a container. That’s because water has a lower viscosity.
Although gas is hovering around only $2.00 per gallon these days, increasing fuel economy is still a top priority for most automakers, due in large part to more strict corporate average fuel economy (CAFE) requirements on the horizon. One strategy automakers are using is widespread use of synthetic lubricants. How do synthetics increase fuel economy
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.
