Toyota Genuine Motor Oil is a Toyota-branded lubricant developed, specified, tested, and approved for Toyota vehicles. Toyota controls the product specifications and branding, but it does not publicly identify one universal manufacturer for every Toyota oil sold worldwide.
Who makes Toyota oil in the United States?
In the United States, ExxonMobil is widely reported by industry sources as the company that blends or manufactures Toyota Genuine Motor Oil. However, Toyota’s U.S. product information does not publicly confirm ExxonMobil as the single supplier for every grade and product generation.
ExxonMobil also owns the Mobil 1 motor-oil brand. The connection between Toyota and Mobil 1 does not mean that every Toyota Genuine Motor Oil product is identical to every Mobil 1 formulation. Toyota-branded oils may use specifications and additive packages selected for Toyota engines.
Does Toyota manufacture its own oil?
Toyota is primarily responsible for setting the requirements for Toyota Genuine Motor Oil. The company tests and approves the lubricant for use in Toyota engines, while physical blending and packaging may be handled by a regional lubricant partner.
The supplier can vary according to the country, oil viscosity, product generation, and contract. Toyota does not appear to publish one worldwide list naming the blender for every Toyota Genuine Motor Oil product.
Is Toyota oil the same as Mobil 1?
Not necessarily. ExxonMobil may supply Toyota-branded oil in the United States, and Mobil 1 is an ExxonMobil brand, but that does not establish that Toyota Genuine Motor Oil and every Mobil 1 product have the same formulation.
The important comparison is whether the oil meets the requirements for the specific Toyota engine. Brand name alone is not enough to determine equivalence.
What oil should Toyota owners use?
- Check the owner’s manual for the required viscosity, such as the specified SAE grade.
- Follow the required performance standard or approval listed for the engine.
- Use Toyota Genuine Motor Oil or an equivalent lubricant that meets the manual’s requirements.
- For a particular bottle, check the label and packaging or ask an authorized Toyota dealer about the manufacturer and specification.
