Established in 1888 and headquartered in Tokyo, ENEOS is Japan’s largest oil company, with manufacturing and sales facilities worldwide. For decades, we’ve partnered with Japan’s automakers and leading race teams, developing advanced lubricants alongside vehicle engineers for optimum fuel economy, maximum power, and long-term protection. Each OEM partnership begins with an invitation from the manufacturer, backed by in-house testing built to that automaker’s exact specification — and today, ENEOS supplies factory-fill and service-fill lubricants to the majority of vehicle manufacturers across Asia. It’s the same standard we bring to every bottle on the shelf.
