No, Seafoam is not a leak detector.

Replace your gas cap FIRST. Common problem.

Next most likely: The evap canister @ left rear of the vehicle. Typically a leak there OR the bypass valve and solenoid next to the canister. Have the system tested with an evap tester to find the source of the leak (dealer or local shop can do this).
