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.

Abstract: Lubricant compositions comprising (a) an oil of lubricating viscosity; and (b) at least one non-metal-containing additive, comprising a nitrogen-containing dispersant having a total base number of at least about 90 are useful for lubricating an internal combustion engine. The lubricants have less than 1.0% sulfated ash and a total base number of at least about 8.5, and at least 30% of the total base number of the composition is provided by non-metal-containing additives. The lubricants exhibit a high TBN without deterioration of elastomeric seals.
