Proven Protection For Fleets and Long-Haul Engines

Extended Drain Intervals — Dyna-Plex 21C keeps engines working harder, longer — resulting in reliable and consistent long-haul performance, decreased downtime and extended drain intervals.

Expert Oil Analysis — For performance reassurance from oil change to oil change, oil analysis offers a proactive maintenance approach allowing customers to monitor oil life, increase fuel economy, and deter potential costly failures.

Proven Protection Against the Elements

Running Clean — From dusty blistering heat and blast-furnace wind to soot-filled lanes of snow, ice and sleet, heavy-duty lubricants must protect against the full range of on-road elements. Dyna-Plex 21C is proven to keep the elements at bay, resisting heat and keeping oils clear of soot and contaminants, even in difficult-to-protect engines and circumstances.

Exclusive Friction Shield™ Formula — All Dyna-Plex 21C Heavy-Duty products include Friction Shield, an exclusive additive package blended with superior base oil for better protection against heat and wear, reducing deposits and running cleaner, longer. These high-viscosity oils won’t thin out or break down when the heat is on, and they’ll keep moving consistently when the temps drop.

P R O V E N

Some companies overlook the importance of grease and transmission fluids. But at PetroChoice our knowledge of the fleet industry and equipment means a walk through the shop uncovers ways to save money.

How often are you changing out a bearing or replacing king pins on trailers? Trucks are running heavier with added weight and friction. If the grease you’re using isn’t staying in place, you’ll be paying more for parts. Finding the right fluids can save equipment costs, extend the life of parts and decrease down time.
