Tri County Motor Sales has an on-site bulk DEF system. We are able to provide our customers with 2.5 gallon jugs, 55 gallon drums, and 330 gallon totes.

Since 2010, diesel units have used Diesel Exhaust Fluid (DEF) in compliance with the EPA’s Clean Air Act. DEF is an exhaust after treatment that reduces dangerous NOx emissions.

We use ArmorBlue DEF and it’s composed of 32.5% urea and 67.5% de-ionized water and burns at 3% per gallon of diesel.

ArmorBlue DEF is manufactured to ISO 22241 specifications and is API certified. It is compatible with Tier 4 final compliant equipment using Selective Catalytic Reduction (SCR) technology.
