For more than 75 years, API has led the development of petroleum and petrochemical equipment and operating standards. These represent the industry's collective wisdom on everything from drill bits to environmental protection and embrace proven, sound engineering and operating practices and safe, interchangeable equipment and materials. API maintains more than 500 standards and recommended practices. On this site we introduce API's most important lubricant standards.
ACEA ACEA Europe
The European Automobile Manufacturers Association (ACEA), founded in 1991, represents the interests of the fifteen European car, truck and bus manufacturers at EU level. Through its specialist working groups and an extensive network of individual experts from Member Companies at all levels of the industry, ACEA has access to a wealth of expertise and applied technical experience which is unsurpassed in the EU. ACEA oil sequences define the minimum quality level of a product for presentation to ACEA members. ACEA itself does not certify oils or license or register compliance certificates. Oil manufacturers are themselves responsible for carrying out all oil testing and evaluation according to recognised practices. On this site we present the current ACEA oil sequences.
Why are specifications important?
Choosing a motor oil for our car is not as simple now as it used to be. As the emission limits get severer and severer and car manufacturers are designing more and more complex engines the demands a lubricant is facing are getting rather high.
Oil companies are doing their best to comply with the new demands and to make the best possible products for your car. But if everyone claims to have the best oil how can you choose?
This is where specifications get into the picture. Several independent organizations - like API and ACEA among others - are working on creating a classification system for the oils that creates order from chaos. Their aim is to maintain a set of specifications that help the manufacturers and the consumers to compare the different products and to choose whatever is right for their vehicle.
But some vehicle manufacturers did not find these standards good enough for their lubrication needs. So they created their own standards (OEM standards) and they require an oil to meet their specifications before allowing it to be used in their vehicles.
This site is dedicated to introduce the most important independent and OEM standards to help you choose the right oil for your car, van, truck, motorcycle, motorboat and so on.
