What is Diesel Exhaust Fluid?

Diesel Exhaust Fluid, or DEF, is an emission control agent designed to neutralize harmful emissions and help improve air quality. In January of 2010, the US Environmental Protection Agency implemented emission standards for medium and heavy-duty vehicles. What’s more is that low DEF levels can cause vehicle speeds to be throttled and even cause refusals to start-up. Don’t let low DEF levels slow you down!

How Much DEF Does My Truck Fleet Need?

The amount of DEF you require depends on the composition of your fleet. Number of vehicles, annual mileage per vehicle and average miles per gallon all factor into how much DEF your fleet will need to keep running smoothly. Diesel Direct developed a convenient resource to help estimate the amount of DEF your fleet consumes.
