Supplying DEF to Businesses across Louisiana and Beyond

EPA emissions standards now require many diesel-powered vehicles to reduce nitrogen oxide emissions through a process called selective catalytic reduction (SCR) which injects ultrapure urea — aka diesel exhaust fluid (DEF) — into the exhaust stream of your diesel vehicles. SCR converts toxic nitrogen oxide fumes into a harmless mix of H2O and nitrogen gas. As an authorized distributor of TerraCair’s UltraPure Diesel Exhaust Fluid, Richard Oil and Fuel, a RelaDyne Company provides a high quality DEF product.

As your complete diesel fuel delivery partner, Richard Oil and Fuel, a RelaDyne Company helps you remain compliant with EPA regulations by handling all your DEF distribution needs.
