Flow Resistance? Viscosity? It's Simpler Than You Think

Viscosity is a term that gets thrown around a lot when referring to motor oil, but what does it mean, and how can you find it? The latter part is quite easy, to find the viscosity rating of your motor oil, just look at the two numbers on the bottle.

But what exactly is viscosity? In short, it's the thickness of a liquid and governs its flow resistance. A highly viscous fluid like honey will flow slowly, and a low-viscosity fluid like water will flow quickly. On multi-grade oil, the rating will look something like "10W-30." The former is cold viscosity, which should generally be low, and the latter is hot viscosity, which will usually be higher.
