ABSTRACT:
Methods for regenerating or improving the regeneration of a particulate filter and for improving the performance of a particulate filter during the operation of an internal combustion engine comprise lubricating the engine with a lubricant composition comprising additives that when combusted can form an ash deposit in the filter. The methods are particularly useful for diesel particulate filters on diesel engines that are equipped with an exhaust gas recirculation system.
