PEAK adds oil for SCR and CNG/LNG engines

Aug. 26, 2014

As diesel engines adhere to 2010 EPA requirements, fleet managers are adjusting their maintenance protocols accordingly. PEAK Commercial & Industrial, the makers of BlueDEF, has introduced 10W-30 motor oil specifically engineered for SCR engines. The company also developed products specifically for the growing compressed natural gas (CNG) and liquid natural gas (LNG) engine market.

 SCR engines operate at higher temperatures that not only burn off harmful emissions, but also allow the engine to use fuel more efficiently. This increased efficiency combined with PEAK Premium Synthetic Blend SCR HD 10W-30 Motor Oil, can increase fuel economy up to 4.5% (versus 15W-40 in exhaust gas recirculation engines).

With the increased engine temperature with SCR engines, negative effects on the engine can occur, such as corrosion and soot-induced wear. PEAK SCR Diesel Engine Oil is engineered with an advanced dispersant chemistry that:

  • Stops soot agglomeration from preventing proper engine lubrication
  • Protects against corrosive wear common in SCR engines
  • Reduces oil consumption and emissions
  • Resists viscosity loss and thickening from heavy soot loading and oxidation
  • Reduces sludge and carbon deposits
  • Offers low-temperature pumpability which enables faster start-up and reduced engine wear in low temperatures
  • Protects against “sheer down 

Major engine manufacturers Detroit Diesel, Volvo, and Cummins have approved PEAK’s 10W-30 motor oil.

 For the growing CNG and LNG markets, PEAK Commercial & Industrial is unveiling specialty engine oil. PEAK 15W-40 CNG and LNG Engine Oil is a low-ash, heavy-duty engine oil designed for use in bus, delivery and service truck fleets where compressed natural gas, liquefied natural gas or propane is used. It meets Cummins CES20074 and Detroit Diesel PGOS 93K16 quality level requirements and is designed specifically for oxidation and nitration resistance.
