I agree. Just b/c there is no proven science behind it doesn't mean that it doesn't work. I've been using authentic Walkerswood Jamaican Jerk Chicken Seasoning for years in my gas tanks and I consistently get 800-975 mpg. To be honest the stuff is a pain in the ass to get since I have to go to Jamaica, and some times it's sold out when I get there, but in the end the gas mileage savings always makes it worth it. Plus my fellow motorists love me for it since the resulting exhaust has a pleasant jerky smell that is reminiscent of an authentic Jamaican BBQ. Yahh Monnn! I get people giving me the
dozens of times daily.
