Review on Stant OE Equivalent Fuel Cap: Unmatched Quality and Performance by Pressure Cook

Really wanted it to work. My check engine light is on and someone suggested replacing my gas cap as a possible solution. I put it on, heard a click etc. It seemed to fit my car perfectly. I used up a full tank of fuel much quicker than usual. striking. I put the old cap back on and my mileage is back to normal. (The check engine light never went off either, but that's another issue) Next time I'll just go to the auto parts store.
