All Gumout fuel additives include specific directions for use. But each product has also undergone rigorous “no harm” testing and can be used as often as every fill-up. Our usage recommendations for each product are based on testing in a number of different vehicle types, though the benefits in your vehicle may vary. For best results, use these products at least as often as recommended on the package label.
