takin a long ride in the car this week, and i was wondering about some of the fuel additive out there. ive seen ones that claim they clean different parts or increase mileage some how, or increase engine life, all you have to do is add to the fuel tank.
is there any truth to any of these products, or are they just wastes of money? with the cost of gas going up and being a long trip, even a little would help.
