How Does Synthetic Motor Oil Increase Fuel Economy?

Positive about Gas Prices

Increasing fuel economy remains a top priority for most automakers. Corporate average fuel economy (CAFE) requirements may be in flux, but gas prices continue to inch upward.



What Happens if I Use the Wrong Weight (Viscosity) of Oil?

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.



Lubricant Viscosity Explained

Pouring Motor oil

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.



What Does Viscosity Mean (and How Does it Affect Your Engine)?

Kinematic Viscosity-Oil vs Honey

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.
