DEF Anti-Crystallization Treatment

The Problem

Over time Diesel Exhaust Fluid (DEF) can dry out, leaving behind deposits in the diesel exhaust system. With the buildup of these deposits come increased backpressure, robbing your engine of power and fuel economy. Furthermore, buildup in the DEF injector can produce a poor spray pattern, leading to increased DEF consumption.

The Solution

Bardahl’s DEF-SHOT™ eliminates deposits left behind by DEF in the diesel exhaust system and prevents new deposits from forming, reducing backpressure, optimizing injector spray patterns and reducing operation and repair costs.


  • Eliminates and prevents DEF deposits in the diesel exhaust system.
  • Restores optimal DEF spray pattern, reducing consumption.
  • Reduces DEF consumption.
  • Prevents costly repairs.


Add 1 bottle to a DEF cube/jug prior to fill up. One bottle treats 2.5 gal (9.46 L) of DEF. Dispose of any used or unused solution in accordance with the local, state and federal regulations.
