Rislone Hy-per Diesel Complete Fuel System Treatment improves the quality of Diesel fuel by increasing its cleaning ability, adding lubrication, removing contaminants, fighting corrosion, and helping to prevent the fuel from gelling & going bad. This one dual cavity bottle contains the same amount of additives equal to a bottle of regular injector & complete fuel system cleaner, anti-gel cold flow improver, fuel stabilizer & conditioner, Cetane booster & diesel treatment, ULSD sulfur substitute, and UCL pump & injector lubricant. Simply put, it is the best all in one diesel fuel additive money can buy. Works with ALL: Ultra Low Sulfur Diesel (ULSD), Regular Diesel, Biodiesel Blends, Direct Injected (DI), Indirect Injected (IDI), Turbo Direct Injected (TDI), High-Pressure Common Rail (HPCR), and Turbocharged Engines. Use with ALL: BlueTEC®, Cummins®, Duramax®, EcoDiesel®, Navistar®, PowerStroke®, TDI® CleanDiesel and many more. Heavy Duty Top-Lube improves fuel lubricity to protect fuel injectors and pumps from wear, especially in todays severely refined diesel fuels. Cold Flow Additives inhibit wax crystal growth, reducing fuel pour point and cold filter plug point even in harder to treat diesel fuels. Reduces CFPP up to 20°F (5°C). Fuel Stabilizer Antioxidant retards oxidation, reduces sludge formation, inhibits fuel decomposition and provides fuel stability for storage. Cetane Improver raises the Cetane number of diesel fuel to improve cold stars and reduce misfires, warm-up time, black exhaust smoke, and emissions. Typical numbers show a 1 to 2 point increase in Cetane Number CN per ASTM D613 engine test. Dual clean-up and keep-clean formula removes injector deposits, prevents and estores lost power and improves fuel economy. Real world testing shows an average fuel economy increase of 7.3% and an 87% power recovery with regular use. Includes a specially designed spout which allows it to be poured into all fuel tanks, including those with misfuelling devices.
