Diesel Exhaust Fluid (DEF) Delivery

Looking for Diesel Exhaust Fluid Delivery Services? Contact us today. We are your experts in Lubricants, Oils, DEF, Antifreeze and Performance Fuels. Be sure to ask us about our Custom Blending services as well.


Our headquarters in Oconomowoc, WI makes for the ideal location to fully utilize the railways built and in use since 1896 to receive and distribute products via the Canadian Pacific Railway system.

We have chosen to utilize this resource as this mode of transportation provides for the most time and cost efficient method for delivering products over long distances as well as the safety procedures for industrial grade cleanliness for products such as Diesel Exhaust Fluid. This ensures that the product arrives at our facility in the OEM quality in which it was produced from the manufacturer. Loads received via rail are received into our warehouse through dedicated piping that gets double filtered through a 1-micron filter and sampled for later inspection.

To further ensure the quality of the product received by our customers, we put just as much attention and care into the delivery of this product as it was received. All unloading of product from the Corey Oil DEF truck is dispensed through double filtered dedicated lines through a dedicated 1-micron filter and then into our customer’s tank passing through a Micro Matic valve. Micro Matic valves remove the potential of external contamination from the surrounding environment. This is an example of a Closed Loop System, which is the only way to properly dispense DEF to ensure a positive experience for the end user.

If you would like more information on DEF, procedures involved, or proper handling of DEF, please feel free to call Corey Oil at (262)-966-0868.
