Syn V EMD™ is recommended for EMD / GE diesel engines with silver-coated bearings.

Syn V EMD™ keeps EMD engines much cleaner than mineral EMD oils while providing superior anti-wear / anti-scuffing / anti-seizing protection.

Syn V EMD™ greatly extends oil and filter change intervals and reduces the fuel consumption and high oil consumption common in most EMD diesel engines.

Syn V EMD™ is formulated with Royal Purple's proprietary Synerlec® additive technology, which is proven to make equipment run smoother, cooler, quieter, longer and more efficiently. It leaves a thin, tough, protective film on all metal surfaces, which protects engines by providing instant lubrication upon startup and acting as a preservative oil during shutdown.
