i would say that is not if it is a locking gas cap or not. i bought two gas caps. one at the local auto parts store and one offline. the one i got from the auto store i checked the threads with my stock gas cap and it was entirely different so i took it back because it wouldn't fit on all the way. i ordered one from curtesy parts.com and it has the matching threads. and i can't imagine this one causing any problems. still no large evap leak from my truck since i cleaned the vent control valve.
