UTILISING ACEA CERTIFIED LUBRICANTS PROVIDES YOU WITH A GUARANTEE OF QUALITY AND WILL PROTECT YOU AND YOUR CUSTOMERS THROUGHOUT THE WARRANTY PERIOD AND BEYOND.

WHAT IS ACEA?

ACEA is the European Automobile Manufacturers’ Association and represents Europe’s car, van, truck and bus manufacturers. They are the European equivalent of the United States’ API (American Petroleum Institute). The ACEA Oil Sequences define the minimum quality level for service fill engine oils. Service manuals regularly recommend ACEA as well as API and JASO specifications. If an OEM mandates these specifications, using products without the required ACEA specifications can void the warranty and may provide inadequate engine protection.

THE IMPORTANCE OF INDUSTRY AND OEM RELATIONSHIPS

Castrol works very closely with a number of OEMs globally,  including Jaguar Land Rover, Ford, Mazda and Volkswagen, to develop advanced lubricants that meet all the requirements of each OEM. This demonstrates Castrol’s ongoing commitment to providing high quality lubricants that have been developed through key industry and OEM relationships. Industry and OEM relationships provide hard evidence that a lubricant manufacturer’s products will perform in today’s advanced technology engines, protecting your customer’s vehicle throughout its entire life cycle and long after the warranty period has expired.

ACEA SEQUENCES AND AFTER TREATMENT DEVICES

The latest version of the ACEA Oil Sequences focus on improved robustness and biodiesel compatibility.

ACEA defines three engine classes:

  • A/B: Gasoline & Light Duty Diesel Engines (Without after treatment devices)
  • C: Gasoline & Light Duty  Diesel Engines (With after treatment devices)
  • E: Heavy Duty diesel engines

Each ACEA Sequence is  governed by a set of parameters including fuel economy and SAPS  levels (Sulphated Ash, Phosphorus and Sulphur). These are outlined in Figure 1. The terms Low, Mid & High SAPS refer to the ACEA limits on certain additives that can be incorporated into an oil. The limits are set to protect after treatment devices (i.e. particulate filters and three way catalysts). Always use a lubricant specified by your OEM to avoid damage. All ‘C’ approved oils are catalyst compatible oils, however various technologies are employed by manufacturers to meet relevant emission levels. This results in different chemical limits and fuel economy limits within the C classification.  Note that HTHS (High Temperature, High Shear) is the best indicator of fuel economy. As per Figure 1, a lower HTHS value indicates greater fuel efficiency.
