How much DEF will my truck use?
One gallon of BlueDEF™ is used approximately every 300 miles. A truck with a 20 gallon DEF tank can go up to 6,000 miles between fill-ups.
Will a truck stop if it runs out of DEF?
No. An engine will not be shut down or be unable to restart as a result of running out of Blue- DEF™. However, if the DEF tank is empty, engine horsepower will de-rate and BlueDEF™ should be added to the tank.
Will DEF freeze in cold weather?
DEF begins freezing at 12° Fahrenheit (-11° Celsius). If DEF freezes, the engine will start and run properly (no de-rate or malfunctioning lights). A DEF tank heater will thaw the fluid for use and at no point will this affect the operation of the engine.
