Patent Summary

Fuel compositions containing metallic additives for particulate trap regeneration in diesel engines, stabilized against phase separation by the addition of a specific organic compound having two or more contiguous polar head groups. The compound, typically a polyisobutenyl succinic acid derivative, is added in small amounts to prevent separation of the metal catalyst compound from the fuel, enabling its effective use in low-sulfur diesel fuels.
