Diesel Exhaust Fluid (DEF) Experts

Diesel Exhaust Fluid, commonly known as DEF, is the most sensitive material to cleanliness issues of your vehicles, equipment, and investments. Due to this sensitivity, the objective is to keep the fluid as clean as possible and to handle any DEF with caution.

Corey Oil uses and distributes Blue Sky DEF, an API registered, OEM recommended, nationally recognized product that meets the ISO 22241-1 standard for Diesel Exhaust Fluid.
