Premium Raiload Engine Oils

Product Description

DIOL RD 13 RD 40 and 17 RD 40 oils are premium crankcase lubricants for locomotive diesel engines. These products are designed to meet the severe service demands imposed by newer railroad diesel locomotive engines. Each is formulated using high quality base oils and an additive package endorsed by equipment builders and meets the applicable requirements of General Electric (GE) and Electromotive Diesel (EMD) for their modern engines.


Features and Benefits

LMOA Generation 5 is the latest and most demanding quality for diesel locomotive engines. A Generation 5 oil must incorporate improved additive technology to handle the high demands of extended oil drain intervals. Increased levels of insolubles must be well dispersed in the lube oil to minimize wear. At the same time, effective TBN and oxidation control must be maintained. The results of using such a lubricant are:


Cleaner engines due to reduced deposits

Reduced maintenance due to extended drain intervals


DIOL RD Series products incorporate additive technology designed for LMOA Generation 5 performance. They also meet the requirements of GE Generation 4 Long Life specification and are posted on the Internal Listings of GE and EMD. Furthermore, DIOL RD Series products are zinc free, low chlorine, and non-corrosive to silver bearings and other engine metals.
