A method for determining the type of fuel used by a vehicle includes receiving hydrocarbon speciation and nitrogen-oxygen compound data from an emissions sensor. The hydrocarbon speciation data is compared to one or more hydrocarbon threshold levels, and each threshold level corresponds to an anticipated fuel type. The nitrogen-oxygen compound data is compared to one or more nitrogen-oxygen compound threshold levels, and each threshold level corresponds to an anticipated fuel type. Based on the comparison of the hydrocarbon speciation and nitrogen-oxygen compound data to threshold levels, an anticipated fuel type is determined.
