SPC EMD G517 is a premium LMOA Generation 5, high alkaline reserve, 17 Base Number, zinc-free diesel engine oil formulated to provide superior performance in modern high output railroad diesel engines burning very high sulphur fuel.


SPC EMD G517 meets the following performance requirements:

•     LMOA “Generation 5” Specification


SPC EMD G517 provides the following benefits:

•    High TBN content which enhances performance to keep engine running cleaner, smoother and longer.
•    Contains excellent detergency and dispersancy to resist formation of lacquer, varnish, sludge and other deposits in the engine system.
•    Prevents piston rings sticking and keeps piston clean.
•    Resists oil oxidation under high temperature operation.
•    Excellent antirust and anticorrosion properties to protect the engine against corrosion from arduous acidic by-products of combustion.
•    Excellent anti-wear properties to prevent premature failure.
•    Provide the most effective antiwear protection available for silver and bronze metallurgy.
