Can sleep at night knowing I have this gas cap on my truck
Bought this because we have an older diesel truck that someone was able to siphon our gas from, keys work great, the cap fits great, easy to unlock and lock again, and our hard earned money for diesel will never be stolen again! Overall very easy to use.

Turn til it clicks on the truck then it frees up and spins.
Works Great. Actually a bit more quality for the price I thought I was going to get. Once in the locked position, put it on the car or truck. Tighten it til it clicks. At that point it frees up in reverse and will just spin and not unscrew.

Very cheap quality.
Cheap . Plastic. Broke before even used 1x. I HOPE, nothing fell into my actual tank when the whole locking mechanism just broke trying to turn the key the first time to lock it…
