Def fluid

The Walmart brand meets all of the required specifications and is pharmaceutical grade Urea with double distilled ionized water. The only problem I am aware of is some scum bag people purchase DEF and refill the original container with plain water and return it to Walmart for credit. Therefore when you purchase the DEF at Walmart or other stores with return policies, make certain that the container has a seal under the cap and is not out of date.
