Operating agricultural, construction and heavy-duty machinery across the mid-20th century Great Plains took guts and a lot of good oil. Hundreds of small company specialty brands claimed to work best. But when the U.S. military needed a heavy-duty line of lubricants for their own high-stakes missions, Dyna-Plex 21C was called for duty. Product development, decades of testing and new custom blends followed — and a proprietary brand began to rival all the majors.
Highest quality oils and lubricants are made using the highest-quality base oil. Blended with premium elements at every step of the process, and boosted with additive packages designed for each application, Dyna-Plex 21C products are uniquely formulated to protect the world’s toughest equipment.
Select Dyna-Plex 21C products carry Friction Shield protection, an exclusive PetroChoice offering. The Friction Shield designation is an assurance of the best possible equipment protection from metal-on-metal wear.
