it will help minimally. for better gas milage, get the mile-service interval closest to your milage on your car, it is all inclusive. Try to use Seaform brand top-end cleaner in your PCV valve, gas and oil.

You don't clean it, you replace it. It will then pass the smog test if you're in one of those states.
