DIOL 11 RD 20W-40

Railroad Crankcase Oils

DIOL™ 11 RD series oils are premium heavy-duty crankcase lubricants for locomotive diesel engines. These products were developed to meet the stringent performance requirements of Tier 4 locomotives. Older locomotive engines will also benefit from using the DIOL 11 RD series. An Electro-Motive Diesel (EMD) and General Electric (GE) endorsed additive system provides excellent engine protection, enhanced oxidation performance, improved oil consumption control, and enhanced Alkalinity / TBN retention, and oil drain interval extension capability*.

*Compared to DIOL 9 RD series

 

Features and Benefits

•  Zinc Free - Excellent Silver Bearing Lubricity

•  Enhanced Oxidation, Sludge-Soot Handling and Viscosity Control

•  Excellent Deposit, Corrosion and Wear Control

•  Formulated for use with low sulfur and ultra-low sulfur diesel fuels

•  Chlorine Free

 

Applications

DIOL 11 RD oils are formulated to an LMOA Generation 7 quality level with an engine manufacturer endorsed additive package. They meet the requirements of for all EMD and General Electric diesel locomotives.

 

The DIOL 11 RD product line incorporates a field proven additive technology that offers enhanced oxidation performance and wear inhibitors. This addresses the deleterious effects of lower oil consumption and engine modifications in the new Tier 4 locomotive engines. The DIOL 11 RD series offers enhanced Alkalinity / TBN retention, oxidation and thermal stability, and better acid control
