DEF is urea that helps clean the exhaust before it's released from your vehicle. DEF stands for diesel exhaust fluid just in case you were wondering. If your vehicle has a DEF system on it, then it's required for the engine to run correctly. If your DEF system fails, then it will put your pickup into limp mode. This is when you will have a lack of power and eventually, your pickup will stop running.
Depending on the manufacturer of your vehicle will depend on the type of DEF fluid that you need. 2012 was the last year that it wasn't federally mandated that you had to have a DEF system on your diesel vehicle. Ford and Chevy both went to the DEF systems before it was mandated, and Dodge switched in 2013. If you have questions give us a call at 541-791-2886 and we would be happy to help.
