Couple weeks ago, while not paying attention, I filled up the 750 w/ 87 octane thinking it was my Chrysler 300 daily driver .... noticed it when the car had filled up, somewhere at 1/2 tank, CEL came ON with code P2402, drove till I had 1mile to E and filled up with the Premium (Shell as always) reset the light with OBD scanner and light came back ON, im on my second tank and I have done like 5 resets and light comes on within 10miles, I tried adding octane booster as well to the premium to no avail, even bought a new gas cap just in case...no luck ...
Could it be I need to drive a lot more miles for car to reset itself or what else can I try???

Replaced Leak Detection Pump, its located on the passenger side wheel, remove covers and its located right by the tank, took less than 2 hours.
