What does low diesel exhaust fluid mean?
Emissions regulations in the U.S. don’t allow diesel vehicles to operate in the absence of DEF if it’s required by their exhaust design. If the light is ignored for too long, the vehicle will likely go into a reduced power mode. If the DEF level falls too low, the engine will not start until fluid is added.
How often do you have to refill diesel exhaust fluid?
every 5,000 to 6,000 miles
The typical DEF tank will be approximately 15 – 20 gallons, thus requiring a fill every 5,000 to 6,000 miles.
What is the diesel exhaust fluid symbol?
The symbols to the left indicates that the Diesel Exhaust Fluid (DEF) (AdBlue) is low. The fluid creates a catalytic reaction that removes particles from the exhaust. When low, the fluid must be topped off. The fluid will need to be replaced if it is contaminated.
Can I use water instead of DEF?
For the O/O’s using DEF, you can use distilled water instead.

What happens if you run out of diesel exhaust fluid?
What happens if you run out of diesel exhaust fluid? Diesel exhaust fluid is used to reduce NOx emissions. You will get a lot of warnings to refill the DEF tank before you run out. If you decide to ignore the warnings or the circumstances do not allow tank refill, the engine is designed to limit its power and fuelling dramatically.

But low-quality DEF can still cause problems. If a truck is running low-quality DEF, there are a number of issues that may occur, some of which could even void a vehicle’s warranty. This includes catalyst poisoning, deposits, and injector/filter clogging. Repairs can be very expensive and downtime may be extensive.
