Choosing the right motor oil is based on two important parameters that are essential characteristics of all motor oils. These parameters are API and SAE, two global standards found on the packaging of all gasoline and diesel engine oils. Along with the vehicle’s user manual, they guide you in selecting the appropriate motor oil.
API represents the quality level of motor oil and stands for the American Petroleum Institute. This organization classifies motor oils based on whether they are used in diesel engines or gasoline engines. For example:
Each type of oil is defined by a set of specifications determined by the API standard. These specifications take into account:
Motor oil manufacturers are required to comply with these standards.
SAE indicates the viscosity grade of motor oil and stands for the Society of Automotive Engineers. This organization classifies engine oils based on their viscosity.
According to SAE standards, motor oil can be:
Today, most modern vehicles use multi-grade oils. The SAE J300 standard defines specific characteristics for oils based on their viscosity grades, ensuring their usability within the engine’s operating temperature range.
The year of manufacture and engine design technology also play a role in determining the right oil.
After understanding these concepts, the first step in choosing the right motor oil for your car is to consult the owner’s manual. All car manufacturers specify the suitable viscosity grade based on engine design and operating temperature. The chosen oil should:
The manual also recommends the appropriate API quality level, which considers:
Example: Consider the Renault Logan (Tondar 90).
According to the vehicle’s owner’s manual (as shown in the image referenced), the recommended motor oil must have:
If you do not have access to your vehicle’s owner’s manual, you can visit the official website of Petrosanat HoorAsia at www.kingpowerlub.com.
