What is Def and how does it work?

As we talk about fuel and businesses requiring a variety of oil-related products, you may have been left wondering, “What is DEF?”. The short answer is that DEF, or Diesel Exhaust Fluid, is an important component in keeping heavy-duty trucks and machinery operating within federal emission guidelines.

What happens when you run out of Def?

At 5%, the light starts flashing, and when levels drop below 2.5%, it turns solid. When DEF runs out entirely, the light turns red, and the truck is electronically limited from going more than five mph. DEF levels can also be checked manually.

It’s contained in a reservoir separate from the fuel tank and is metered into the engine’s exhaust stream to control certain emissions. Inside the exhaust pipe, the DEF vaporizes and decomposes into ammonia and carbon dioxide.

What happens when Def level reaches 0.8 gallons?

When the DEF level gets to 0.8 gallons, the check engine light will also come on, and the van will tell you that you only have a certain number of starts left. After that, it will go into limp home mode and you won’t be able to drive at speeds above 5 miles per hour. The sensor in the DEF tank seems to still be an engineering work-in-progress.
