A method of optimizing usage of post-injection strategy for improved cabin comfort in a vehicle includes detecting a set of conditions corresponding to parameters pertaining to the vehicle's hardware components, driving components and operating conditions. If one or more of the set of conditions are satisfied, the method implements the post-injection strategy for the vehicle, for a pre-determined time, if the fuel-oil ratio for the engine of the vehicle is lower than a pre-determined value.
