What ACEA A/B Demands of an Oil
The ACEA A/B sequences cover gasoline (A) and light-duty diesel (B) engine oils for European service, without the catalyst-protecting low-SAPS limits of the C sequences. A/B formulations rely on conventional detergent/dispersant systems, antiwear and antioxidant chemistry tuned for higher-HTHS European drain intervals.
CheMost supplies the additive components a blender uses when formulating an oil to meet ACEA A/B. The category approval itself is held by the finished-oil marketer, not the additive supplier — the grades below are the chemistry that goes into such formulations.
