YOGYAKARTA Not a few of us are confused when we see the code and numbers on the engine oil packaging. In fact, the code provides important information about oil specification, such as the level of congestion, quality standards, to the type of oil that suits the vehicle engine. For this reason, it is important to know how to read the engine oil code so that it is not wrong when you want to buy it.

Compiled from various sources, there are at least three types of machine oil codes listed on the bottle, namely the SAE (Society of Automotive Engineers), API (American Petroleum Institute) and JASO (Japanese Automotive Standard Association)

In the SAE code, it is usually a combination of numbers with letters. For example, 10w-40, or 20w-50, and so on.

The combination of these figures indicates the level of thickness of the engine oil, so you can choose the lubricant that suits your engine needs.

Generally, the smaller the number ahead, the more oil will be. Letter W after the numbers ahead signify as the meaning of a winter or winter.

Here are some examples of SAE codes for oil and how to read them:

SAE code 10w-30

SAE code 10w-40

SAE 5w-40 Code

SAE code 20w-50:

Furthermore, in oil with the code API (American Petroleum Institute), you can see 2 additional alphabets behind the API oil code.

For example, API SN or API CH, the first letter to determine if the type of gasoline vehicle is represented by code S, while the diesel engine uses the code letter C.

For the second alphabet, explain the latest quality of car oil. For example, the SN API has better oil quality than the SG API. The new oil, the alphabet code will be further away.

In the oil with the code JASO (Japanese Automotive Standard Association), this code is only intended for motorcycles, not cars.

The JASO code on engine oil is usually followed by MA or MB. Both refer to different usages. The oil with the code JASO MA is perfect for motors with wet couplings such as ducks and sports.

There is also the code JASO MB which is intended for automatic oil. JASO MB oil is generally used on skutik motorcycles that have dry coupling. This type of oil has a lower friction power than JASO MA.
