Dyna-Plex 21C Corvus Railroad Engine Oils

Dyna-Plex 21C Corvus Railroad Engine Oils

Heavy-Duty Off-Road

Dyna-Plex 21C Corvus Railroad Engine Oil is formulated to meet the performance requirements of locomotive diesel engines designed around the strict EPA Tier 4 emission standards. This lubricant provides balanced performance incorporating complex detergents, advanced dispersants, and superior oxidation and wear inhibitors to effectively address the detrimental effects of lower oil consumption and engine modifications in new and remanufactured Tier 4 Tier 3, Tier 2+, Tier 1+ and Tier 0+ locomotives.

  • Meets the latest LMOA Lubricant Oil Classification and LMOA Generation 7, which supersedes previous LMOA classifications
  • Satisfies EMD and General Electric locomotive diesel engine requirements
  • Backward compatible for older EMD and GE locomotive diesel engines, plus legacy models from Bombardier, Detroit Diesel, ALCO, and Fairbanks Morse
  • Recommended for railroad locomotive diesel engines and mediumspeed stationary and marine diesel engines
  • Meets 184drain interval requirement by providing control of rocker box deposits and sludge formation

Dyna-Plex 21C Draco

Dyna-Plex 21C Draco

Heavy-Duty Off-Road

Dyna-Plex 21C Draco is a premium grade, high viscosity index, low pour product which meets the specification AAR-M-963-84. Dyna-Plex 21C Draco contains a balanced heavy-duty additive, which will protect new journal bearings during the critical break-in period and minimize friction in heavily loaded bearings. An additional rust-inhibiting additive further enhances the rust and corrosion protection afforded by the heavy-duty additive combination.

  • Formulated and recommended for yearround use.
  • Recommended for traction motor support bearings and for lubrication of the truck center plates of locomotives.
