“The ultimate guide to PTT Lubricants engine oils certified by 3 global standards: API, ACEA, and JASO.”

Certified by 3 global standards to ensure the best engine oil formulas!  

One of the most common questions car owners ask is, ‘Which engine oil is right for my vehicle?’ or ‘Which engine oil is the best?’ The answer may not be about price or brand alone. What truly matters is whether the engine oil meets recognized global standards as they confirm that the product has undergone strict testing under a wide range of operating conditions and can deliver the protection it claims.   

PTT Lubricants engine oils have been certified by three leading global standards, API, ACEA, and JASO, covering American, European, and Japanese vehicles. This ensures that every drop of PTT Lubricants engine oil is developed to truly meet the needs of your vehicle.  

Let’s learn more about these 3 standards and how they can help you make the right choice in your next purchase! 

API (American Petroleum Institute): international standard from the United States of America  

API is an international standard from the USA and is considered the world's most recognized organization for engine oil and lubricant standards. Therefore, the API symbol on the label confirms that the product meets minimum requirements for engine protection.

Why is API standard important for modern vehicles?

API standard has been developing constantly to keep up with modern gasoline engine technologies, particularly the direct-injection gasoline engines (GDI and Turbo-GDI), that require higher levels of protection. The standard includes:

• Enhanced valve and piston protection: helps reduce sludge buildup and wear on critical components operating under high temperatures  

• Enhanced timing chain protection: prevents wear and stretching of the timing chain, one of the major problems that leads to high repair costs  

• Compatibility with GPF (Gasoline Particulate Filter) vehicles: the new standard features low ash component to protect the Gasoline Particulate Filter (GPF) from clogging, essential for modern European gasoline vehicles. 

ACEA (European Automobile Manufacturers Association): strict European standard  

ACEA is a standard established by a group of European automotive manufacturers. This standard is known for its strict product testing that covers harsh driving conditions and high speeding that are typical of European usage.

The ACEA classification is important in helping you identify the engine oil best suited to your vehicle. Understanding it will allow you to make a more accurate choice of engine oil.

• ACEA A: gasoline engines without a gas particulate filter (GPF)  

• ACEA B: light-duty diesel engines without a diesel particulate filter (DPF)  

• ACEA C: light-duty gasoline/diesel engines with gas particulate filters (GPF and DPF) that require low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil to prevent filter clogging

• ACEA E: heavy-duty diesel engines of trucks or commercial vehicles focusing on durability under heavy operation and extended oil change interval   

JASO (Japanese Automotive Standards Organization): exclusive standard for Japanese vehicles 

JASO is the Japan automotive engine oil and lubricant standards organization that has been founded by a group of leading Japanese automobile manufacturers. Despite being primarily known for its standards for motorcycles (e.g., JASO MA/MB), JASO has also established standards for diesel engines.

• Diesel engine vehicles: it has been established to accommodate Japanese diesel engines that are designed differently from those in European or American vehicles  

• Motorcycles: separated standards are established to ensure the compatibility with the operation of wet clutches and gears in motorcycle engines  

Conclusion for the question “which engine oil is good for my vehicle?”

Whether you drive an American, European, or Japanese vehicle, your best choice is the engine oil with either of the API, ACEA, and JASO standard. When you see these certifications on PTT Lubricants products, you can be confident that they have already been tested by internationally recognized standards. PTT Lubricants’ products are developed to protect every engine component under the most demanding conditions for confidence in power and performance on every road!
