Review on Stant 17511Y Keyed Alike Locking 🔒 Fuel/Gas Cap Review: Medium, 1-Pack Detailed Analysis by Charles Chambers

The reason I give 1 star is not because the product doesn't work properly. I'm giving 1 star because the product made my engine light come on so I can't use it. My check engine light came on after I just removed it for an engine check. A technician at my local shop called me back where he showed me the lid was leaking fumes in what should be a sealed system. In my condition, I cannot pass a vehicle inspection with my lights on, so unfortunately I cannot use this product. This only recently started after almost 6 months of use so I'm not sure what caused the leak but the tech said aftermarket caps are notorious for leaking.
