Review on 🔒 Fokes Locking Gas Cap #10504 77300-47020 - Secure Fuel Cap for 4Runner, Tacoma, Tundra, Acura, Honda, CRV, Infiniti, Mazda, Nissan, Buick, Cadillac, GMC by Jeff Vasquez

Whilst it is not listed as one of the vehicles to fit our 2021 Buick Encore we ordered it anyway. Looks like the threads are the same as our factory cap and we took a chance. We called our local Buick dealership and were told the gas caps hadn't been changed since the 2017 model. Since the 2017 Buick was on the list, we ordered it. It just fits perfectly and after making sure the dash light doesn't come on we're very happy we now have a jamming gas cap.
