The BlueDEF® Purity Guarantee: We test each batch of BlueDEF® before we put our name on it. The batch code found on the box is your assurance that the DEF within is pure and has been tested to meet or exceed the strictest OEM standards, including the API DEF Certification, and the ISO Standard 22241.
BlueDEF PLATINUM® will never compromise on purity. With continual use, BlueDEF PLATINUM® reduces the formation of deposits that build up in your diesel exhaust system.
