NOMENCLATURE & ACEA PROCESS:
Each set of sequences is designated for consumer use by a 2 part code comprising a letter to define the CLASS (e.g. C), and a number to define the CATEGORY (e.g. C1).
In addition, for industry use, each sequence has a two-digit number to identify the YEAR of implementation of that severity level (e.g. A1 / B1-04).
The CLASS indicates oil intended for a general type of engine - currently A / B = gasoline and light duty diesel engines;
**C = catalyst compatible oils for gasoline and diesel engines with after treatment devices. **
Other classes may be added in future if, for example, Natural Gas engines prove to require oil characteristics which cannot readily be incorporated into existing classes.
