Mazda does not manufacture its own branded oil. The oil sold under the Mazda label is produced by a third-party manufacturer under contract. This is standard practice within the automotive industry. Specifically, Mazda Genuine Oil is currently manufactured by Idemitsu Kosan Co., Ltd. for North America.
Using an oil that meets Mazda’s specifications is vital for maintaining engine performance and longevity. Choosing the correct oil viscosity is crucial for proper lubrication and can affect fuel economy and cold-start performance. While Mazda recommends its branded oil, other oils meeting the necessary specifications can be suitable alternatives. Historically, several companies have produced oil for Mazda under its brand, including Total and Idemitsu.
