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.

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.
