Gas caps generally have a long lifespan, but like any other car part, they can wear out or fail. Typically, a gas cap can last up to 5 to 7 years under normal conditions. However, its lifespan might be shortened due to factors like frequent use, exposure to extreme temperatures, or if it's not properly tightened. If you notice your 'check engine' light is on, or if there's a noticeable fuel smell from your car, it might be time to check or replace your gas cap.
