Negative Positive
Title: easily removable while locked
Review: This cap seemed good at first. However closer inspection reveals that this will only deter the least determined of gas theives, and is more of a visual deterrent then an actual security device.A close look at the design of my filler neck reveals the nubs on the cap just sit behind the guides on the filler neck. They don't lock in. What this means is that if you pull up on the cap and turn, there is a friction battle between where the spinning top contacts the base of the cap and the nubs against filler neck. Guess which has less friction... the nubs against the filler neck. For this design to work, the cap would need to spin on ball bearings, or something else that has less friction then the nubs against the filler neck.Bottom line: If you pull up on the locked cap with gentle to moderate force and turn the cap, it comes right off. The design of the filler neck plays a role, so this may not be true for all cars, however it is true for my Saturn Ion.
