An effective mixture of additives that clean and maintain diesel fuel systems. Prevents corrosion, increases lubrication thus reduces fuel pump and injector wear. Increases Cetane value for improved engine performance, easier starting and lower emissions. Regular use keeps the fuel system in perfect working order.\nDiesel additive to maintain and improve performance. Cleans, lubricates and raises Cetane level. Improve corrosion protection, gas mileage, emissions and smoother idle. Add contents every 1,200 miles to 25-150 liter (7-40 gal) of fuel.\nThe can is sufficient for up to 150 liters (40gal.) of diesel fuel.Effect lasts up to 2000 km(1200 miles).
