No matter the weather, your car is always expected to run without a problem. On hot, humid days you want to be able to crank that engine and get the A/C running stat. The same can be said for the reverse, when you jump into a freezing car and wait for the heat to circulate.

But to weather the weather, an engine requires protection from the elements and that comes from motor oil or lubricant. And, as a car cycles through different seasons, so too does its motor oil. Its properties are affected by many things, including the temperature, and since motor oil reduces the friction in engine parts, having the right consistency, or viscosity, is crucial.

Viscosity refers to the thick consistency of the fluid. When temperatures soar, the oil thins out, moves faster and becomes less viscous. When temperatures drop, the same oil thickens, moves slower and becomes more viscous.

Synthetic oils, like Mobil 1 Annual Protection, contain specially engineered molecules that allow it to perform—no matter the environment. Additionally, the properties of synthetic oil keep it from breaking down as fast as conventional oil due to extreme heat or cold exposure.

This is the science that allows synthetic oil to run smoothly and quickly at the turn of a key. They can also extend engine life, when used correctly.

Watch the video below to learn more about viscosity and its role in keeping you comfortable in your travels.
