ACEA (Association des Constructeurs Européens d'Auto mobiles) has officially replaced CCMC since 01.01.1996. This organization defines the quality of engine oils according to European specifications. ACEA classifications use the acronyms A1, A2, A3 A5 for gasoline vehicles. Abbreviations B1, B2, B3, B4, B5 are used for diesel engines. For the Euro 4 standard or higher, there are oils with Low SAPS or Medium SAPS for gasoline or diesel engine vehicles with exhaust gas aftertreatment (ie thread filter). These oils also carry the identification codes C1, C2, C3 or C4. The abbreviations E2, E3, E4, E5, E6, E7, E9 are valid for diesel engines in commercial vehicles and business machines. The additional number indicates the performance criterion.
