ACEA Meaning
ACEA oil classification is a system used to classify engine oils for automotive use. The system was developed by the Association des Constructeurs Européens d’Automobiles (ACEA), and is widely used in Europe.
There are three different classifications within the ACEA system: A, B, and C. Class A oils are intended for use in gasoline engines, while class B oils are intended for use in diesel engines. Class C oils are a combination of the two, and can be used in either type of engine.
The ACEA system is not used in North America, where the Society of Automotive Engineers (SAE) has its own classification system. However, many North American oil manufacturers produce oils that meet ACEA specifications, and these oils can be used in European vehicles.
If you’re shopping for motor oil, you may see the ACEA classification listed on the bottle. It’s important to choose the right oil for your engine, so be sure to check your owner’s manual to see what classification is recommended.
ACEA Standard
ACEA is an association of european automobile manufacturers. The first letters of the ACEA standard indicate the class of vehicles for which the oil brand is intended for. The standards are explained below.
A/B – oils for gasoline and diesel engines (before 2004 A – auto oils for gasoline engines, B – for diesel engines).
C – a class of oils for gasoline and diesel engines that meet Euro-4 environmental standards. Such oils may be used together with catalysts and particulate filters which reduce the level of pollutants in exhaust gases.
E – oils, designed for powerful diesel engines.
The number after the letter characterizes the oil subclass, and the last two digits after the hyphen indicate the time of adoption of the specification.

Frequently Asked Questions (FAQ)
ACEA C3 oils offer improved protection against wear and tear on engine components at higher temperatures. They also protect against sludge formation and oil oxidation due to their added detergents and dispersants. The downside is that this thicker oil may reduce performance somewhat as it is not as efficient in terms of fuel economy compared to thinner ACEA C2 oils.
