DEF - Diesel Exhaust Fluid


Diesel Exhaust Fluid (DEF) is used to reduce NOx emissions. It is a mixture of deionized water and chemically pure Urea. This is not a product that you add to your diesel fuel. There is a separate 15-20 gallon holding tank where it is injected into the diesel exhaust system. Your vehicle will not properly operate without DEF. When DEF levels are low, you will notice a loss of horsepower, and when it is absent, your vehicle will only be able to go a limited speed and eventually idle mode only.
Your instrument panel should have a gauge that will notify you when levels are becoming low. For any other questions on DEF contact our service department at 530-458-2151. http://www.hoblitmotorsford.com/service-department/
