Royal Purple Synergy


  | Product Sheet

Synergy® is Royal Purple’s best-selling EP gear oil and is designed to smoothly lubricate gears under virtually all conditions.

Synergy® is an ultra-tough, long life, gear oil with slippery, synthetic molecules, which greatly increase its lubricity and oiliness properties. Gears run smoother, quieter, cooler, longer, and more efficiently without overhauls.

Synergy® gains its performance advantages over competing mineral and synthetic oils through its superior blend of synthetic base oils plus Synslide® additive technology, Royal Purple’s unique, proprietary, noncorrosive, EP technology.

Synergy’s ability to rapidly and completely separate from water prevents sludge and water commonly found in wet gear boxes (such as cooling tower gear boxes).

Synergy® protects gears in severe service applications where other EP oils often fail and is recommended for users looking for longer oil life and significantly improved gear box reliability and performance.
