AMSOIL and Gearbox Express partnership showcases renewable energy in Wisconsin

Superior, Wis., USA – May. 1, 2019

AMSOIL PTN 320 has been selected as the factory-fill and factory run-in oil by Gearbox Express, North America’s largest independent remanufacturer of gearbox assemblies and main shafts for the wind turbine industry. The partnership shines a light on a growing industry in a state not yet widely known for wind power.

"We are proud to strategically partner with another Wisconsin company in the renewable energy sector,” said Bruce Neumiller, CEO of the Mukwonago-based Gearbox Express. “It’s an exciting time of growth in the industry, and Gearbox Express is leading the charge by strengthening alliances to bring more value to our customers."

AMSOIL headquarters are in Superior, and it was chosen by the remanufacturer for its technical support and the long runtime of its flagship gear oil, which is currently over the 10-year mark.

"AMSOIL and Gearbox Express are both committed to a high standard of innovation, customer service and product longevity, and we share a focus on technology and data,” said AMSOIL Vice President, Wind & Industrial Dave Meyer. “This benefits the industry by contributing to sustainability and efficiency. Through a high-tech focus on fundamentals, we’re extending change intervals and maximizing the service life of every wind turbine."


AMSOIL combines next-level service with advanced lubricants to extend gearbox life, reduce maintenance costs and enhance turbine efficiency, making it the OEM factory-fill and service-fill choice for the global wind energy market. For more information, visit Follow AMSOIL Wind on
