Diesel Exhaust Fluid

Central Oil & Supply is a proud distributor of Blue Sky DEF.

 

DEF is a solution of urea and

de-ionized water that, when injected into the exhaust stream (a process known as selective catalytic reduction, or SCR), eliminates 90% of exhaust pollutants by converting them to nitrogen and water.

Tier 2 Bin 5 emissions standards currently require all new diesel vehicles on U.S. highways to comply with stricter emissions standards set forth by the Environmental Protection Agency (
EPA). Blue Sky meets or exceeds all of the International Organization for Standardization (ISO) requirements for use in SCR systems.
For more information on DEF and recommendations on how much will be needed for your fleet, please contact us at 1-800-883-8081.
