Review on 🔒 Enhanced Security for Diesel Vehicles: Stant Diesel Only Pre-Release Locking Fuel Cap by Jose Wititsuwannakul

Bought for my 2015 GMC Sierra 2500 Denali HD. The lock works great. The seal creaks a bit on the first few turns, but that noise has since gone. To install the lock, turn the key and remove it from the cap. Then rotate it two clicks. Then the top spins for free indefinitely. Turn the key to unlock, leave the key in the cap and turn to unlock. It was pretty easy. By no means indestructible if someone wants to steal your diesel, but it does protect my €150 investment somewhat. The trick is to deter the thief as much as possible and make life difficult for him. This is important.
