A lower number like 5W means the oil remains thinner in cold conditions, allowing it to circulate quickly through the engine components, while a higher number like 10W is slightly thicker but still suitable for moderate cold climates. The "W" rating ensures that the oil maintains the correct viscosity profile, balancing flowability when the engine is cold and protection when the engine is hot.
W Grade Oil Cold Flow Benefits and What It Means for Engine Performance
When you glance at the label of your favorite cooking oil, you might notice a small letter stamped on the bottle, often a prominent "W" nestled within a circle or shield. The Origin of the Standard The presence of the "W" is rooted in a classification system developed by the American Petroleum Institute (API).
The Science Behind the Symbol Modern oils are multi-grade formulations, meaning they are engineered to perform effectively across a wide range of temperatures. This system was created to provide a uniform method for grading engine oils based on their viscosity, or resistance to flow.

Understanding what does the w in oil mean demystifies this symbol and empowers consumers to make confident choices at the grocery store. The number preceding the "W" is the viscosity grade, such as 5W or 10W.
