As an economical choice for fuel tank maintenance, it negates the need for expensive fuel polishing or tank cleaning services. Its concentrated nature means that a little goes a long way: with just 1 ounce needed for every 4 gallons of fuel, a single 64-ounce bottle can effectively clean a 256-gallon tank and 128 ounce gallon can clean 512 Gallons. Whether you're dealing with a personal craft or a commercial fleet, STAR BRITE Star Tron Fuel Tank Cleaner delivers on the brand's promise of quality and effective engine maintenance, ensuring your vehicles run cleaner and last longer. DIRECTIONS: Add 1 fluid ounce for every 4 gallons of gas or diesel fuel. Allow to sit in the tank for a minimum of 24 hours before using rejuvenated fuel. Note: Keep spare fuel filters on hand. Star Tron Tank Cleaner will disperse hardened deposits and can load or clog filters. After two treatments, the fuel tank should be cleaned of all deposits and fuel filters will no longer load or clog up. After using this product to thoroughly clean fuel tanks, maintain the system with Star Tron Enzyme Fuel Treatment to prevent future carbon buildup and gumming.
