Review on 🔒 Stant Flex Fuel Regular Locking Fuel Cap - Secure Yellow Cap for All Fuel Types by Jim Fuhrer

I would not recommend this product, especially in cold weather. Keys are cheap and easily bent. Even in good weather, the keys are difficult to put in the lock. When it got really cold, the keyhole froze and only worked with the WD40 combo and pumping it up, adding ten minutes to the gas. In the end, the entire internal key mechanism came right out of the gas cap, rendering the product unusable.
