    Not sure if it's working.
    Maybe the car is running just fine and this isn't making much difference. There doesn't seem to be any gain or loss of gas mileage. If you have a single use bottle of fuel cleaner, save it. You can use a funnel to fill the bottle with the Lucas Oil 10013, then pour it in the gas tank easily.
