Best DEF fluid For Powerstroke

Diesel trucks are powerful vehicles. This is probably one of the reasons why Ford decided to name the engines “Powerstroke.”

Best DEF fluid For Powerstroke

When something as powerful as a diesel truck operates, it releases multiple pollutants into the atmosphere. Thanks to awareness and sensitivity towards the environment, companies have come forward to take steps to reduce the emissions. One such step is the use of diesel exhaust fluid (DEF). Ford joined the bandwagon too to ensure that when the fuel burns, the environment is not affected as much. 

DEF Fluid – A Brief

DEF consists of deionized water and carbamide (urea). The carbamide is, however, not the natural ingredient. To formulate DEF, synthetically made carbamide is used. This particular fluid is only used in vehicles that have an SCR or Selective Catalytic Reduction System. Today, all leading brands use SCR, abiding by the mandate in 2010 to meet low Nitrogen Oxide standards.

DEF has a shelf life of around 3 years when stored in optimal conditions – between 23 and 68 degrees F. Any fluid older than 3 years can have harmful effects. It can contaminate the whole system.
