    Great added piece of security!

    I had an angry ex girlfriend pour sugar down the gas tank of my last car, and now that I finally own a Mustang I definitely didn't want that happening again. It's very well built and stylish looking for the price. Installation was under 5 minutes and it works great and stays secured. You'll need both hands to unlock it, but the added security and peace of mind that no one can get to the gas tank is well worth it!

    Looks good

    I have concerns that it is not fully closing. It only turns once before clicking which seems strange. It is a very nice looking cap but the lock does not seem very good.

    Adds a retro look with security!

    I ordered this cap when my original OEM one started separating it top from its threaded collar (!) I was hesitant to pay this much money for a gas cap, but it is actually quite a substantial, solid piece of billet aluminum, much more substantial than the plastic two piece thing from the factory. This is reminiscent to me of the '60's gas caps, and has the added benefit of using the locking the mechanism if you need that extra security. *Note- you DO NOT HAVE TO use the locking feature to use this cap! It does not have a tether, but that was not an issue for me, as I wouldn't want this cap dangling from the outer gas door and possibly scratching the side of the car! The knurled outer edge and indents on the surface make it easy for even large hands to grip. I would definitely recommend this fuel cap, and am very glad I took the chance and bought it! (By the way, American Muscle delivers FAST! Thanks for that free and fast shiping!)

    Billet Locking Fuel Cap

    Product works well and looks very good. However the lock was very stiff and turns counterclockwise. Better instructions would have been helpful. I was concerned that the key would break off in the lock.

    I recently had my gas tank syphoned!!! yes, at a 1.40 liter up here in Canada....I am not surprised it happened. And no I don't have the Trailer Park Boys as neighbors. Thankfully no damage to the internals or further mischief. So with this in mind I bought this locking gas cap, looks great and is strongly recommended.

    High Quality "Locking" Cap

    This is a heavy duty, sharp looking "locking" fuel cap. It is a two-handed operation, the cap will spin freely when locked and you need to hold it immobile with one hand and use the other hand to turn the key. I am perfectly fine with that. I wanted a locking cap. The handful of negative reviews seem to be based on the locking function but that is what it is. Understand before you order it that it is a locking cap. It is well built, has an excellent lock and looks sharp but if you are want to pass on the locking function it may not be the cap for you.

    Protecting your engine

    So you've spent tons of money perfecting the looks of your pony and spent tons of money building up your motors HP. Looks great and runs like a lightin bolt. The someone who's jealous or just wants to get back at you SUGARS your gas tank! This locking gas cap will rid yourself of that worry. No modification needed just remove the stock cap and install this one and you can sleep with no worries.

    Great quality, Great appearance

    Looks great, little bit of a pain at first screwing on and off but once you get used to it its no problem. Locking feature is nice but I don't use it. Combined with the Shelby Fuel Door really fine tunes the look. Didn't seem like that big of an appearance upgrade at first but once I installed them both I am glad I did. Other mustangs without seem to be bland and lacking.

    Great Looking and Locking Fuel Cap

    I bought this fuel cap because as you all know our fuel doors don't lock. I did not want anyone messing with my fuel. I've heard stories of sugar in the gas tank, water, etc. And that's the last thing you want to worry about. Do instead of getting a plastic dinky one, I got this. Feel, fit, and finish are great. But there are only two things that bug me, when you screw it on, it engages/locks in two revolutions. Its not like the stock one that you turn 3 times or so. Its just a mental thing that makes you think its not fully seated/threaded. But I have had no issues in 2 months. The other is the locking part. You need two hands to lock and unlock it. As when its locked, it spins freely, so you have to hold it with one hand and turn the key with the other. That's it... It works and keeps your fuel safe.

    Great looking and great quality

    I really like this gas cap. I wasn't very worried about someone stealing my gas but it's nice knowing no one can take my very expensive premium fuel. The cap looks really nice and is nice and heavy, the right amount of heft to suit a Mustang. It's easy to lock once you get used to it.

    Doesn't lock easily !,

    Using it I found that there is a certain way to lock it it doesn't lock unless you turn the key in the lock after you put it back on and then it's still not so easy not the locks of old where you would unlock with one turn and then take the key out and turn it to lock it you can't seem to do that with this lock instead you seem to need a locking system which I am having some difficulty discovering want one that is much easier like the old kind which again as I said would lock upon return to the tank and then you would remove the key needs some more experts to work on it further would not recommend it
