locking gas caps are OEM quality both in construction and materials as well as deterrent to fuel theft and vandalism. A gas/fuel cap performs three very important functions; safety of the vehicle's occupants, fuel economy and reduce emissions. Safety: Without a fuel cap, gasoline vapors will be present around your car at all times. Those vapors can be ignited by a random spark or flame and are very dangerous if you are involved in an accident or rollover. Fuel Economy: According to Sun Oil Company research, a vehicle with a missing or inoperative fuel cap will allow pounds (22 gallons) of gasoline to evaporate over the period of one year. Emissions: Gasoline vapors emit hydrocarbons which dissolve the earth's ozone layer and cause smog.

Complete garbage. Returned it right away.
Got it, put it in at home, drove to the gas station to fill up, and the lock broke. Would not lock again just stayed unlock.
Didn't replace it, if that's the garbage quality coming from Stant I don't want to risk having it break where it won't unlock and then I can't fill up.

Fits 2015 Nissan Xterra. Even though Amazon's website says it won't fit. So far I've driven about 600Km with it and no engine check light.

To unlock: use the key turn 1/4, turn back to original position, remove key, then unscrew.
To lock: tighten the cap until it clicks a few times, key is not required. When locked the black part of the cap just turns freely from the white part.

The cap doesn't feel all that solid. So I am not certain how long the locking mechanism will last.

So far so good. Fits my 2001 GMC Sierra 1500 SLE Ext Cab perfectly. Keeping the old fuel cap in case this one develops air leaking issues.

I just wish this cap had the seam around the edge to fit the factory gas cap leash. That would make it perfect.

Horrible and cheap product. Broke down after few weeks. Needed to go to locksmith to have it removed, as the dealership couldn't do it. Don't get this unless you want problems.

Feels cheep , I’m worried it’s going to break at the worst time .

As advertised. Would have gotten 5 stars, if I could hang it from my gas cap cover, like the OEM gas cap. Not a big problem, though, as I just put the key and the cap on my tonneau cover when I'm filling up.
