We report for the first time the application of turnaround-point long period fiber gratings for wavelength encoded detection of automobile fuel adulteration. The demonstrated high sensitivity of 0.96 nm/% change of kerosene in petrol up to 10% adulteration is significantly high compared with previously published values. These specialty gratings can easily detect the presence of 1% contamination of kerosene in petrol and thus provide opportunities for development of portable fuel adulteration sensors.
