ACEA specification information for passenger car motor oils
The European Automobile Manufacturers' Association (ACEA) unites Europe's 16 major car, truck, van and bus makers. For the European automotive industry, a baseline of engine oil specifications, known as European Oil Sequences, define the minimum quality level of service oils as defined and requested by ACEA members for use in their vehicles. On top of the ACEA European Oil Sequences, OEMs have their own specifications and distinct requirements. Once successfully tested and approved by the respective OEMs, these specific OEM approvals can be added to the ACEA claims.

European oil sequences for passenger car engine oils
A/B category (including A7/B7)
The ACEA A/B categories are designed for high performance gasoline and light duty diesel engines and provide the minimum performance required for many OEM specifications. The A7/B7 category requires additional performance for low-speed pre-ignition protection (LSPI), engine chain wear protection and turbocharger deposit control.
C2/C3 categories
ACEA C category oils are stable, stay-in-grade engine oils intended for use as a catalyst compatible oil in vehicles with all types of modern aftertreatment systems. To ensure compatibility with aftertreatment devices, the SAPS limits of lubricants have been significantly reduced as they can negatively influence the performance of aftertreatment devices.
C5 category
The C5 category involves very low viscosity (high-temperature, high-shear (HTHS) minimum 2.6 mPas) engine oils, providing improved fuel economy. These mid SAPS oils are compatible with aftertreatment devices and intended for use in highly loaded direct-injection gasoline and diesel engines.
C6 category
C6 based oils provide additional performance needed for today’s modern engine technology. In addition to fuel economy and lower viscosities, the C6 category also provides LSPI protection, engine chain wear protection and turbocharger deposit control.
