Review on Filler Compatible Chevy Cadillac Saturn by Alan Pfeiffer

I've been trying to turn off the check engine light on my '06 Suburban for months. After replacing the evaporative sensor and canister purge valve, I still had the EVAP Big Leak Code. After that I checked the whole car for smoke (fog), there were no leaks except the gas cap spewing "smoke" out of the smoke machine. I ordered this after trying the stock Autozone and Oreilly gas caps. Bloody skeptical and tired of buying refurbished or non-working new parts, I ordered this gas cap. Well since I drove to work two days ago the check engine light went out and never came back. thank you, thank you, thank you very much!
