Plymouth Lubricants has partnered with Brenntag, the world’s largest DEF distributor, to supply Brenntag Ultrapure Diesel Exhaust Fluid. Brenntag has received certification from the American Petroleum Institute (API). This certification recognized that Brenntag DEF meets the stringent quality standards that engine manufacturer service warranties specify. Brenntag is the preferred Diesel Exhaust Fluid of several leading original truck producers (OEMs) such as Ford, Daimler, Hino, Volvo and Mack Trucks North America. Additionally, Brenntag is endorsed by many professional transportation partners.


DEF is a nitrogen-based urea solution that helps clean the air by reducing the nitrogen oxide (NOx) emission from the exhaust stream of diesel engines.


The market for DEF is being created due to the new emission requirements set forth by the EPA to meet the most recent Clean Air Act specifications.

Plymouth Lubricants currently offers DEF in totes, drums and cases as well as offering many types of dispensing equipment designed specifically to be compatible with DEF.
