Review on ACDelco GM OE GT264 Locking Quarter Turn Fuel Tank Cap - Includes 2 Keys, Black by Sherman Lancaster

UPDATE: A few months later I got the "Tighten fuel cap" message on the dash. I have a 5.3 petrol engine. It worked great on my 2004 GMC Yukon XL SLT. Cap 1/4 turn. I've had it for a few months now and have had NO check engine lights. The only downside is that I couldn't transfer my stock gas cap leash to this new cap. A small sacrifice so people don't steal my gas overnight. Comes with 2 keys and a genuine AC Delco product.
