1. A method of reducing the impact of deposits in the post combustion system of a diesel engine, the method comprising:
combusting in the engine a diesel fuel composition comprising as an additive a nitrate compound and/or a peroxide compound; and
measuring the interval between regenerations of the diesel particulate filter, wherein the nitrate compound and/or peroxide compound reduces deposits in the post combustion system of the diesel engine and increases the interval between regenerations of the diesel particulate filter compared to when an otherwise identical fuel is combusted under identical conditions except for the inclusion of the post combustion deposit reducing additive.
