Diesel Exhaust Fluid (DEF) is a water-urea solution (32.5% high-purity urea and 67.5% deionized water). It is non-toxic, nonflammable, non-hazardous and non-explosive.
The purpose of DEF is to reduce nitrogen oxide (NOx) concentration in the exhaust emissions produced by diesel engines. The process by which NOx emissions are reduced is called Selective Catalytic Reduction (SCR).
DEF is generally carried in a separate storage tank in diesel-powered vehicles equipped with SCR technology. DEF is injected into the hot exhaust stream of an engine and absorbed onto a catalyst. In this way it helps break down the NOx gases in the exhaust into nitrogen gas and water vapor, both harmless to the environment.
In order to help reduce smog and air pollution, the U.S. Environmental Protection Agency issued NOx emissions standards in 2010 for diesel vehicles of all sizes. These emissions standards are very stringent and most light-duty and heavy-duty trucks are not able to meet the standards without using SCR.
In addition to helping to meet NOx emission standards, DEF can also provide fuel savings. Fleet experience with heavy duty trucks model year 2010 and newer suggest 5% fuel savings compared to 2007 model year vehicles with similar engines.
Not all DEF is created equal. You should make sure the DEF you are purchasing meets industry standards, including API and ISO requirements, to ensure it is manufactured properly, to high-quality standards, and is doing the job it’s supposed to do.

Woodford is proud to be an authorized Blue Sky DEF distributor. Blue Sky is a premier DEF supplier with regional manufacturing and distribution centers across North America.
One of the best ways to save money on DEF is to make bulk purchases from Woodford. This is cheaper and easier than buying small containers at a retail store and hauling them back to your facility. You’re also assured of receiving high-quality Blue Sky DEF, rather than a lower quality brand.
Woodford is well equipped to handle our customers’ DEF needs, and we can deliver on your schedule. We offer a wide range of quantities based on customer requirements—from basic 2.5-gallon containers to much larger, bulk quantities. We can also provide on-site storage tanks if necessary, and arrange ongoing deliveries to ensure you never run out of DEF.
