The disclosure relates to a method for receiving in-vehicle information regarding diesel fuel cloud point condition. The method includes establishing communication between a telematics unit in a vehicle and i) a global positioning system device, ii) a call center including a database, and iii) a cloud point monitoring device in the vehicle. The telematics unit receives from at least one of i, ii, or iii, information pertaining to vehicle location, cloud point, and ambient temperature. The telematics unit determines from the information whether fuel in a fuel system of the vehicle is reaching cloud point or can reach cloud point within a given time period. The telematics unit then transmits an in-vehicle alert when the fuel in the vehicle fuel system is reaching cloud point or can reach cloud point within a given time period. The disclosure also relates to a system for performing the method.
