Pioneering innovation
Pioneers of 0W-20 Development
Nearly two decades ago, Idemitsu collaborated with Honda to innovate a lower viscosity oil aimed at enhancing fuel efficiency for hybrid vehicles. The breakthrough Idemitsu 0W-20, crafted with specialized additives for improved stability, became the chosen oil for Honda's new Insight Hybrid. This initiative paved the way for its adoption in non-hybrid models and caught the attention of other leading Japanese automakers, leading to widespread use among major brands by 2009.


Earning Trust
Trusted Factory Fill for Honda, Toyota, and Nissan vehicles
In 2010, Idemitsu introduced the 0W-20 oil in the United States, quickly becoming the standard for numerous Honda, Toyota, and Nissan vehicles manufactured in the country. Given the increasing regulatory demands for better fuel efficiency, American automakers are now considering Idemitsu 0W-20 as a potential solution to meet these requirements.
