SCR engines operate a higher temperatures, this not only burns off harmful emissions but also allows the engine use fuel more efficiently. This increased efficiency combined with PEAK Heavy-Duty 10W-30 CJ-4/SN Synthetic Blend Diesel Engine Oil for SCR Engines can increase fuel economy up to 4.5%.*

Increased engine temperatures can cause negative effects on the engine such as corrosion and soot-induced wear. PEAK Heavy-Duty 10W-30 CJ-4/SN Synthetic Blend Diesel Engine Oil Uses an advanced dispersant chemistry that stops soot agglomeration from preventing proper engine lubrication and subsequent engine wear.

• Advanced dispersant technology prevents soot agglomeration
• Protects against corrosive wear common in SCR engines
• Reduces oil consumption and emissions
• Shear down protection
• Resists viscosity loss and thickening from heavy soot loading and oxidation
• Sludge and carbon deposit reduction
• Low temperature pumpability enabling faster start-up and reduced engine wear in low temperatures

PEAK® Synthetic Blend SCR Diesel Engine Oil is recommended for use in all heavy-duty diesel engines including engines equipped with a Selective Catalytic Reduction (SCR) system. It meets all industry standards and manufacturers’ requirements.
