Motor Oil Numbers, What Do They Mean?

You might notice that all motor oils are named using a set of numbers and the letter "W." These are not just made-up names by the manufacturer to look cool and appealing to customers. Those numbers indicate a property of that specific type of motor oil.

The governing body that helped establish this labeling system was the Society of Automotive Engineers or SAE. They made a system that would label or grade motor oils according to their characteristics.

Because temperature affects how viscous a fluid is, in this case, motor oil, manufacturers made it their mission to create motor oils that will work efficiently across various temperatures. They use additives and chemicals on the base engine oil to achieve this effect.

In short, the number you see beside the letter "W" will indicate the oil's viscosity at low temperatures. Meanwhile, the number after the letter "W" will indicate the oil's viscosity at average operating temperatures. As you might have guessed, the "W" here stands for winter.

How Many Kinds Of Engine Oils Are There?

Besides having a specific temperature range in which they will work efficiently, engine oils also have different classifications of the oil. These classifications are often under the three most common types: conventional, fully-synthetic, or synthetic blend.

Conventional Engine Oil

Conventional oil is the most basic of the three types of oil. Before the introduction of synthetic engine oils, people used traditional oil on every kind of engine. It comes from crude oil and is then refined into engine oils. Additives are added to improve the efficiency and engine protection qualities.

The biggest pro of using conventional engine oil is its price. Because it's made entirely from a naturally occurring material, it is cheaper than other engine oils. However, its biggest pro is also its biggest con. It is made entirely from naturally occurring material which tends to be less refined than other engine oil types making it hard to control its properties completely. It also offers a lower degree of engine protection than other oil types.

Fully-synthetic Engine Oil

Fully-synthetic engine oils, as the name suggests, are cooked up entirely inside a lab or a factory. Because of this, they have far more consistent properties than conventional engine oils. Manufacturers use these properties to produce engine oils that are efficient and with the highest level of engine protection.

All these improvements in performance and reliability come at a cost. Fully-synthetic engine oil prices are often 20% higher than conventional engine oil. However, this 20% increase in price also means that your engine oil will last much longer, giving you more savings down the road.

Synthetic Blend Engine Oil

This engine oil can be considered a hybrid mix of engine oil types. It takes all the favorable properties of conventional engine oil and gets mixed with the superior performance and consistency of fully-synthetic engine oils.

Your best bet is the synthetic blend when considering a middle-ground product among engine oils. They last longer than conventional oils and are cheaper than fully-synthetic engine oils. You get the best of both worlds.
