There's only
One Way forward

The name ONEWAY captures a simple resolve: to make a genuinely good oil — not just in words, but by staying the course to the very end. That road runs straight ahead and never wavers. There is only One Way.

Our Origin

Built on manufacturing, proven as a brand

ONEWAY oil is manufactured by Huihong Petrochemical Co., Ltd. — a specialist lubricant maker that has been refining oil since 1973. Seeing that Taiwan lacked a homegrown brand able to stand on the world stage, Huihong set out to develop high-quality, consistent oils — and ONEWAY was born.

In 2005, ONEWAY International Co., Ltd. was founded to take full charge of marketing and sales. Under its leadership, ONEWAY now serves both the Taiwanese market and a growing list of export destinations — China, Malaysia and Singapore.

With more than two decades of local growth, ONEWAY is an oil you can trust — and one ready for the world stage.
